ETN(X) with NHN Plastic

wessonsmith - 10-2-2020 at 12:02

Please watch the video for the details. I will be doing an update to the cardboard detonator. I have made it, so heating is no longer required.

I would like to point out that in the production of this plastic, I am using "wetted" energetics. This has two advantages. It dramatically reduces the sensitivity of the energetics used, and it allows the NHN to more evenly be distributed throughout the composition, creating a very uniform and dense plastic.

Really fascinating. Beautiful color. Wesson, it’s too bad you weren’t active 5 years ago or more. This forum was a hoot then.

Too bad it can’t be initiated by a weaker cap. I bet just NHN would do it?

Herr Haber - 11-2-2020 at 04:30

Just read the comments on the vid.

Different solvents will give different particle size when crashing ETN in water. Have you tried something along those lines for your plastic ?
Thanks for the food for though !

The insensitive nature of the plastic is by design. Since creating #8 power detonators is easy for me, I prefer energetics that is difficult to initiate, much safer. NHN only wouldn't allow for dense plastic, since the average particle size of NHN is 13 µm.

It does seem that this board has died off a bit.

I have tried different solvents and different methods such as recrystallizing from alcohol only. None of the methods produces small particles as easily and in the quantities I want, as NHN does. Since I can very easily produce NHN, it's my goto energetic for small particle size. The steel cutting test shows that it is some very powerful plastic. The best part is it is very malleable and dense.

Have you been able to reliably produce 13µm ETN in quantity? I am aware that PETN and RDX can be readily made into small particle sizes. I have read papers where they use ETN in compositions, as compared to PETN, and talk of the favorable density difference of the PETN compositions due to the smaller particle size.

Tsjerk - 11-2-2020 at 06:24

Nice work! As you make your #8 detonators yourself, can you show what one of your detonators does on the witness plate?

Here is 900mg of plastic at work.

Here is the #8 witness plate test.
https://www.bitchute.com/video/ENn7wI82UTsM/

FYI there is a 4mm gap from the bottom of the base charge, melt-cast ETN, in the detonator to the physical bottom of the detonator due to the fact I am using hot glue as the physical base for the detonator. This gap is why there isn't any damage from the detonator on the witness plate.

Reliably… no. But after reading many times that acetone is too good of a solvent I needed to understand what that meant.
The product was very fine and fluffy. Very far from the sugar-like most people aim for.
Since acetone and methanol wont give the same particle size and that you can also have an influence on that with temperature I thought you might have tried something along those lines.
What do you use to neutralize the occluded acid ? It seemed to me that too had an influence on particle size.

In my experience, the best results for small particle size ETN is to recrystallize directly from ethanol. I use enough ethanol to dissolve the ETN at a temperature of around 40°C, and then place the beaker into a salted ice bath with a temperature of around -15°C. Once the ETN has crashed out into the ethanol, and the temperature has dropped to around 5°C, I quickly vacuum filter it.

This produced 40% of the ETN below 37µm, how much below, not sure. NHN produces a superiorly dense and malleable plastic over my small particle size ETN efforts. The power of plastic using NHN as the small particle size is remarkable, as evidenced by the steel cutting test below.

My neutralization process of the crudely neutralized ETN is to dissolve it in ethanol at 55°C and use Ammonium Carbonate to neutralize any remaining acid. I then vacuum filter and crash the filtered solution into a large bucket of water and crushed ice. This produces ETN that is mainly light and fluffy. It's from this twice recrystallized ETN that I preform the direct from ethanol recrystallization that I mentioned earlier.

**** Here are two more examples of the awesome power of the plastic. 4.76mm and 6.38mm cold-rolled steel

Great work man. like always!

Antiswat - 20-2-2020 at 09:11

i would advise you to ram a bit of aluminium foil into the bottom of the tube, 4mm is quite a standoff really. or just put the tube on a piece of tape, whatever taste you fancy. just some aluminium foil wrapped around bottom of the tube should work too

i recall seeing TACN, the copper salt, even despite it being very well hydrated blowing a very nice hole in what seemed to be 3mm mild steel, very clean hole. maybe TACN should be considered with ETN? maybe gelled with a bit of acetone to see if the brisance suffers from a bit of solvent left in there. i believe both ETN and TACN are quite sensitive to shock, so it shouldnt be too tricky to set off, by chance i have an image of the possible calculated critical diameter of TACN by the youtuber (whos channel is now demolished), but thats TACN on its own.
https://gyazo.com/8e0dc2c81fd76174b72b171ba37d36be

my idea with TACN and ETN is that the density of TACN could maybe be increased, or the compounds would fit in well with each other and boost each other, TACN i believe is a slight bit OB negative contrary to ETN

The reason for the hot-glue method is that I use melt-cast ETN as my secondary. So during the heating process to melt the powdered ETN, the aluminum foil method doesn't always reliably hold in the melted ETN. Since the detonator is pressed into the plastic, the 4mm standoff is irrelevant. The detonation wave blasts out in all directions. The plastic I use is insensitive to 400mg of hand-pressed ETN. For reliable detonation, I need the melt-cast.

Urea stabilized crystalline ETN unmixed with anything has a shelf life of 4 or 5 years in outdoor storage in the semitropical climate, less in warmer areas, and less in mixed compositions.

ETN lacks the inherent stability of PETN and is less inherently stable than nitroglycerine,
comparing better with nitrostarch or nitrocellulose in terms of stability, but ETN is more stable than nitromannite.

Maybe a stabilizer of dicyandiamide or betaine would improve storage stability
for methanol crystallized ETN.

FYI, Urea stabilized ETN will destroy plastic based on HTPB. To get every last bit of acid from my ETN, I dissolve crudely neutralized ETN in 55°C ethanol and add Ammonium Carbonate until the test strip shows neutral.

Much, much better, don't you think? Now anybody can figure out the gist of your work in seconds.

Rosco Bodine - 22-2-2020 at 04:40

@wessonsmith You know that to neutralize initial product is good. Stabilizer can be included as trace ingredient material, a stabilizing deliberate impurity addition to supplement neutralizing. Neutralizing provides a good short term stability but combining neutralizing with trace ingredient stabilizer to supplement neutralizing is done to improve more greatly the long term storage stability.

Even small amounts of Urea in HTPB causes damage. I have never had any issues with my purified ETN. I recently sent off a detonator I made in 2016 , went off without any issue.

The problem with energetics is that one failure will cost you a limb. Or two. The way you hold the 8# in your video will cost you your whole left hand. Fine if you have a spare hand, but I haven't

I appreciate your concern. What you mention is the very reason why I use
NHN. Please also remember that I am using a soft wooden dowel and it's being pressed into a waxed paper cardboard tube. NHN is 80x less sensitive than Lead Azide.

What you say about observed issue of incompatability of Urea and HTPB is not something I dispute or argue.

And your not having any stability issue with only neutralization of ETN is based upon a short term observation not within the scope of making valid conclusions about long term stability.

Do not argue please with someone who 100% knows certain from long term many years observation of pure sample that purified ETN has many years stability but NOT what is very good long term stability.

I gave as examples nitrostarch and nitrocellulose for how stability of ETN is generally comparable with 2 other materials. I gave 2 potential alternative stabilizers that may be useful and not suffer same issues as urea. So there is no argument. But if you do not understand only neutralized ETN stability is good but limited to a very few years, then in a few more years give it time and you will, I positively can guarantee that assertion. :)

Herr Haber - 24-2-2020 at 06:16

If you recrystalize years old ETN it will regain some stability.
Unfortunately the same cant be done for humans.

The pinkish color we dread in ETN cannot be brought back in humans.

Eurenco claims their X-Dough, based on PETN, has a shelf life of 20 years. I have to imagine that ETN based x-dough, which is the Lithium Grease plastic I just made, is at least half of that.

Honestly, that kind of "boundless optimism" is a good way to kill your own credibility. You haven't posted anything about this lithium plastic here (as I've said before I don't consider videos suitable for presenting claims, arguments or data), so I have no idea what you're on about. But either way you can't make assumptions on stability based on entirely different combinations of explosives and binders.

I wouldnt trust any salesman telling me their product has a 20 years shelf life ;)
Eurenco's mini booster is based on their PETN dough and only has a 5 years shelf life.

I cant say I've seen a lot of commercial explosives but I was under the impression their shelf lives were quite short.

Anyway, got some Li grease yesterday :D

Fulmen - 25-2-2020 at 04:57

Actually they list it to >5years, so there isn't any real conflict between these claims. And what's the problem with a claimed 20y shelf life? PETN should have virtually infinite life under good conditions, and the same goes for most binders used in commercial plastics.

What would be the benefit of lithium grease compared to PIB/oil?

The lithium Grease from Walmart is $2.82 for 14Oz.
https://www.walmart.com/ip/Super-Tech-General-Purpose-Lithiu...

It is very easy to use and makes for a dense, 1.58 g/cm³ in the hand, plastic as powerful as that based on the vastly more expensive and harder to acquire HTPB. PIB/oil is a laborious process, extracting the PIB from tape.

Here is a side by side comparison of HTPB and Lithium grease plastic 5.2 g. They are both equally as powerful. You see more debris with the HTPB because I used a small block of wood. The LG side used a long piece of wood, doesn't fragment like the small block. The damage to the steel witness plates is identical.

ETN and PETN are entirely different animals in regards to stability, just as nitrostarch and nitroglycerine are different in stability even though very closely related in chemical composition. pure PETN is inherently chemically stable as is pure nitroglycerine, while pure nitrostarch and pure ETN are inherently chemically unstable. This is not a trivial difference. It is night and day. Which is exactly why stabilizers are used to improve the storage life and storage safety for materials and compositions containing them that do have a limited if indefinite storage life, that certainly is affected by favorable or unfavorable storage conditions.

Fulmen - 26-2-2020 at 11:03

A more relevant question would be how it compares to plain oil or grease. I like lithium grease as a grease, but I'm not sure I'd want that mess with my explosives. But I can imagine it's more water resistant with lithium grease. How would pure lithium soap work? It might produce a decent compressed explosive?

My first batch of "plastic" was precipitated RDX and chainsaw oil. For non-field use it works just fine, but it's greasier and has a mediocre density. The PIB extraction is a bit of a mess, but totally worth it in my opinion. Just let time and solvents do the work.

Lithium Grease plastic has been around since WW2. After all Lithium Grease is nothing more than Lithium stearate & Mineral Oil. Without the thickener of Lithium Sterate you are correct, it wouldn't be very dense or useable in the field.

British PE4 comprises RDX 88.0%, Paraffin Oil 9.6%, Lithium Stearate 2.4%), wherein lithium stearate is a thickening agent for the paraffin oil.
Swedish Sprängdeg m/46, first released in 1946 is PETN based Lithium grease plastic. Not sure why you would be concerned about a binder that has been in use for well of 50 years.

It's VERY cheap and easy to mix into your energetics. Takes me all of 10 minutes using my blender to produce beautiful, POWERFUL, and dense, 1.58 g/cm³ in the hand, plastic:)

If you are using the high velocity high shear mixing of a blender to incorporate a mixture of explosives and binder and reduce the particle size of the HE to a plastic, this is an inherently dangerous process that should be done remotely. This could be done without issue a hundred times and thought to be no significant danger until the exception occurs that atomizes the blender and operator.

What was I thinking ? is a rhetorical question that makes the *precise* point for the next Darwin Award.

Fulmen - 26-2-2020 at 12:38

I must admit I detest metallic soaps on general grounds. They're inherently hard and messy to work with. So I have simply overlooked them for this use. But you're right, it's probably one of the better DIY binders all things considered. I still consider PIB superior but that's a matter of taste.

I am not using a high-velocity, high shear blender, that would be STUPID, and also completely unnecessary.

I am using a regular mixer for bread on the LOWEST speed to start. The mixing blade doesn't touch the sides or bottom of the mixing bowl and I only add 1/5 of energetics at a time until they are thoroughly mixed. Once mixed, a 400mg powdered ETN detonator won't set it off. I thoroughly test ALL my explosive processes to make sure they are safe. My method for producing plastic, using a SLOW mixer, is the same process that the big guys use.

How many on this board use the old rolling pin method? Yeah, that's safe, pressing energetics between a hard rolling pin and a hard work surface, with inconsistent pressure, and the danger of fatigue, what could go wrong:)

That is why I use the bread mixer as described in my other post. 10 min is all it takes to get the plastic you have seen in my videos and pictures. It's amazing stuff, very malleable, even at low temperature, and stores well. Oh yeah, it's VERY INEXPENSIVE:)

I should point out however that the mixer only provides a consistent mixture not a dense mixture. The density of my plastic comes from using two different particle sizes of energetics. 13 µm, which is the average particle size of NHN, and 220 µm, which is the average particle size of ETN. I also use an inexpensive vacuum chamber to remove all of the excess air bubbles that are added when mixing. It dramatically increases the density as opposed to plastic that doesn’t use a vacuum chamber.

Most backyard chemists making plastic don’t incorporate the two particle size method and their plastic density suffers for it.

The absolute CLUELESSNESS of SOME (mostly naive and youthful) "regular Einsteins" is something that never ceases to surprise me about what is a SCIENCE discussion board....

Yet here is on PUBLIC DISPLAY the supercilious nature of a "younger generation" of KNOW-IT-ALLS that SHOWS a lack of "situational awareness" that is an EXISTENTIAL THREAT not only to themselves, but by EXTENSION to the entirety of a world it may well not even be a "future" theirs to contribute any "progress" derived from their "brilliant" insight and depth and genius because they are just "too brilliant" to LISTEN to known GOOD INFORMATION that could have preserved their own LIFE in said world.

What wonderful things those regular Einsteins might have eventually accomplished and shared had they lived longer, is what will too often be the eventual "admiration" of those surviving when reflecting on the lives so sadly, foolishly and needlessly lost.

What wonderful things those regular Einsteins might have eventually accomplished and shared had they lived longer, is what will too often be the eventual "admiration" of those surviving when reflecting on the lives so sadly, foolishly and needlessly lost.


Wow, that's a lot to get off your chest:)

For years there has been a certain mysterious "element" you don't find listed on the periodic table, the "element" called STUPIDIUM, and it has unusual properties that may be known only once "in passing" to an exclusive club as the last thing they discover in this life.

Takes me all of 10 minutes using my blender to produce beautiful, POWERFUL, and dense, 1.58 g/cm³ in the hand, plastic


Yeah riiiiight, using a "blender" that is not really a BLENDER (Osterizer) but is a Kitchen Maid "bread mixer" ....

Wait...Don't tell me let me guess...says somewhere right on the instructions or label it is highly recommended for convenient mixing of explosives but only if the operator stands there looking at it very closely and does the task very carefully of course.

It's the personal touch that does the trick....

I see, now why didn't I "get it"? :P

Rather than ridicule the procedure should we not seek clarification/question/chalenge? Isn't that more in line with the scientific process?

ETN is generally about like nitroglycerine in a solid form ....

So do the math. It's like the most diabolical math exam ever,
where the grade that is earned may come as a misadventure
that is permanently consequential.

And unlike a lot else posted here, that is no *bullshit*.

I now see what your problem with my method is, you have some INCORRECT DATA! Let me clear that up for you. Let’s do the MATH.

Nitroglycerin in liquid form has a sensitivity to impact of 1.8 kgf*cm or 0.176 J. ETN in powdered form has a sensitivity to impact of 33.4 kgf*cm or 3.28 J. So a quick calculation tells us that ETN is 18.6x less sensitive than Nitroglycerin. For reference PETN in powdered form has a sensitivity to impact of 40 kgf*cm or 3.93 J, which makes it 22x less sensitive than Nitroglycerin.

Once the energetic is mixed into the Lithium Grease, a detonator with 400mg of pressed powdered ETN won't set it off. It's this reason why my paper detonators use Melt-cast ETN, which is considerably more powerful than pressed powdered ETN. I need the extra power to actually set off my plastic. Most plastic explosives need a #8 power detonator, which is defined as 450mg of PETN, as reference.

What I think you were doing was confusing ETN in the MOLTEN state which IS AS SENSITIVE as Nitroglyercin. FYI, care to take a guess at how they make Dynamite? Yep, that's right, they put that explosive that is 19x MORE sensitive than ETN into mixer filled with an inert binder and wait for it, MIX IT TOGETHER!

Here are some video clips from the old to the new, of industry making Dynamite and Plastic explosive.

There is still No Way I would choose as part of a "hobby pursuit" to manually operate a mixer standing beside it observing it and especially not using a blender on a plastic composite containing ETN or PETN, but would do that remotely and use solid addition funnel screws also operated remotely, and then if Murphy's Law chooses today to apply, it won't be any huge consequential issue on that operation. Even in a commercial production of such compositions, extruders and mixers are operated remotely and there is a reason for that precaution. I have never manually done any milling operations on any energetic materials or mixtures and I am never going to start. Even solvent aided or melt systems I have limited to under 4 gram samples and then using no glass or metal handling the sample.

Rolling the dice on manually formulating, mixing these compositions is not a gambit I am going to be making, not even with RDX that is "safer" still in terms of the risk. In some kind of war environment being pressed to the ghetto of lower valuation of life and limb it would be a different scenario, but as a risk taking not necessary for a peace time hobby, I'll pass on this manual mixer operation.

Oh and BTW I had already become familiar with dynamite and its inventor and dynmaite manufacture in my studies 60 years ago, along with noting the loss of life in the mans immediate family of his next of kin killed in the family business by being blown to atoms.

First, Nobel's brother died from a nitroglycerin accident, a bottle full of nitro fell on the floor beside him. He didn't die from a Dynamite manufacture process.

You are entitled to have your fears and OPINIONS about things, that's perfectly fine. What I object to is your hostel and combative approach to making your point. For the first few interactions with me on this subject, you didn't provide empirical evidence or make an OBJECTIVE argument. You instead hurled incoherent rambling insults, and made UNSUBSTAINATED and INCORRECT assertions about OBJECTIVE FACTS! ETN is nowhere near as sensitive to Nitroglycerin, yet you stated it as FACT! Then you used that incorrect fact to insult and demean.

I think you need to spend some time reflecting on why you are so angry and determined to demean others on a public board when instead you should be sharing IDEAS and concerns in an objective and sincere way.

I think you guys need to get a grip on the reality of what I am doing. I am SLOWLY mixing a relatively safe to handle energetic(s) 1/5 at a time, into an INERT binder, and when mixed into the said binder, a detonator with 400mg of pressed powdered ETN won't set off. The mixing blade doesn't touch the side or bottom of the bowl. The bottom of the bowl has been pre-coated with the inert Lithium Grease binder futher reducing the possibility of friction.

Please refrain from hyperbole and personal biases. The sensitivity issue you bring up is the reason why after spending months on this board I decided to make NHN. An energetic that is 80x less sensitive to friction than Lead Azide. Yet on this very board, many members think that HMTD, TATP, Lead Azide, etc are somehow acceptable primaries to make and use.

What I have found in the relatively short time I have spent on this board is that there a VERY few members who do their OWN research. Instead, there seems to be a lot of regurgitation of misinformation at the best to flat out FALSE facts, at worst.

When I first came to this board I got a lot of grief for suggesting that people switch to NHN. I was meet with a lot of hostility because I factually pointed out how dangerous and sensitive primaries like Lead Azide were, I guess I was bucking the status quo and it wasn't liked.

As I stated in my ealier post, I have no problem with being called out or CORRECTED as long as it is respectful and is based on FACT! Passing off biases and personal beliefs as a basis for an attack isn't helpful to the discourse of the community.

Wessonsmith... do you know what four hand sign language is? Google it. You would need it if you have a one time accident, but wouldn't be able to do it because you would lack the hands to do so. You would lose your hands because of the explosion, you would lose your eyes because of your own bones forming shrapnel. I don't think I have to explain the deafness part.

Yamoto71 got away, keeping his eyes, because he was working in a fume hood.

I get it. Hydrazine Monohydratye will kill me if I breathe it in. Fuming Nitric Acid will blind me if I get it in my eyes. I can also get killed in a car accident, get a girl pregnant without a rubber, and even with rubber if it's defective. I get the risks involved with doing all those things and I take all necessary and practical precautions.

The guaranteed way to avoid any problems is to lock yourself indoors and do none of those things. But since I like having sex with women, and blowing stuff up, I take reasonable precautions.

Thought I would inject a bit levity into this discussion.

Discourse on this board ....riiiight ....a little depth could help that.

Yeah, Choice is the ultimate freedom. So you go ahead with your own RANT starting with INCORRECT and/or UNSUBSTANTIATED inventor's euphoria "stability" arguments and proceeding with your own confirmation bias blindered brand of "objectivity" about the "safety" of what you are doing, or the illusion of safety, and you go right ahead and do what you think is smart.

I never got down to the bean counting of joules or newtons on measurements in my generalization comparison of ETN and nitroglycerin which is still valid.

And your imprecise and incorrect reference to a "blender" is a HUGE straw man for this expanded ARGUMENT to the commercial production that does use remotely controlled and barricaded facilities .....FOR GOOD REASONS....peace of mind absolutely counting as a good reason, even if for alleviation of unreasoning fears.

I should now descend into chanting mantras for banishment of all my death fears. :D I'll get back to you when I'm all better. :P

In U2U it was clear from you it was like you were asking, and who are you to know anything at all about ETN ....and so I told you, so far as I can tell I am the "who" that dredged up the ETN obscurity from one post read in an old news group alt eng expl and first posted about ETN on another board that was the E&W forum where I gave the patent and literature references and then Axt posted the first synthesis there at E&W and later here on this board. So I personally have observed the stability under more years long storage than you have done, and I know something about that stability to speak with authority in answer to your general SMART ASS "what do you know" kind of question....yet you blow right past that and "move on" making misleading "safety" claims that are highly RELATIVE just like your dubious ETN stability claims.

Who needs a stabilizer for ETN ? What a bizarre idea !!!

And now you are going to school me in good manners and mental attitude and WARP this into some Freudian realm of psychoanalysis. Well go get a mirror for self reflection and look for the sticky about an ETN misadventure at the top of this forum section for edification about "relative safety".

The generalization that ETN is generally like solid nitroglycerin is a fair generalization, and so is the generalization I made about stability.

The numbers can tell part of the story. And the numbers are modeling studies about an observed AND derivative theoretical and predicted reality calculated to entirely govern that universe where ultimately theory may or may not hold true in practice, that is the bane of every bean counting statistician, when SHIT happens not according to the "rules" that theory supplied. The anomaly lurks, and it is invisible in the statistics until it has made a statistic of you.

and get an answer that can't pass through the wall that is your bias. You suffer from overconfidence in "evidence based science" that is a mile wide and an inch deep.

For many of us it happens that our very existence in this world is an ANOMALY that did not follow the prediction of a most carefully considered "mathematical model" ......and likewise it does also occur that a departure from this life as well may be the anomaly.

But there are many who consider themselves "great thinkers" on which the point of this subtle FACT is lost, because they failed to ever have the DEPTH of DISCERNING to understand the SUBTLE difference between what is ACTUAL REALITY and what is only a "mathematical model".

It dramatically reduces the sensitivity of the energetics used, and it allows the NHN to more evenly be distributed throughout the composition, creating a very uniform and dense plastic.

No, you where called out for the hysterical nature of it. No such thing as a dangerous substance, only dangerous people, sensitive fine, but when handled competently (Just like you using a mechanical blender) Is just as safe as any other substance (They are being like you with conventional primaries, hysterical over some thing perfectly safe when handled properly)

Yes we saw how well that worked out, and you still don't understand the principle I was trying convey, then begging fate by rapping your plastic against a hard surface, like I said no such thing as a dangerous compound, only dangerous people.

I wouldn't even do that with C4 and yes, I know how insensitive it is!

When you have the false belief it is safe just because it is insensitive is the time you discover that it decided to play and become unusually sensitive!

With that said, you do you, I will stick with industry / Military standard systems.

and to others yes his method of using a roller style bread mixer is just a scaled down industry method, perfectly fine and dandy.

So long as he's sealed it so no dusts can get inside it.
