PETN mixed with Sylguard 182 in a 4 to 1 ratio of nitrate to polymer produces a material that can be extruded out of a caulking gun and set via heat.
I would like to know more about these use forms. I'm considering a mix using 85% nitromannitol and 15% Sylguard 184 (the 182 seems to be mil spec and
unavailable to the general public at reasonable prices).
What kind of force would be necessary to initiate such a mixture?

Please explain the purpose of diphenylamine.killswitch - 25-9-2013 at 06:58
Stabilizer. It absorbs evolved NO2.
Though I'm unsure if it's necessary in this case.Rosco Bodine - 25-9-2013 at 09:50
cyanoguanidine is a better stabilizer for nitromanniteRal123 - 25-9-2013 at 10:09
Isn't urea and carbonates also good? Some knows the storage stability of MHN?Dany - 25-9-2013 at 13:05

The answer on this problem is impossible in your situation. Nothing is known about the physical properties of your material. Even if all physical
parameters are known, the sensitivity of the material will change from test to another and may not be reproducible even in the same test. the reason
for this is that sensitivity is a complexe feature of an HEDM (see B. Dobratz, PROPERTIES OF CHEMICAL EXPLOSIVES AND EXPLOSIVE SIMULANTS, 1972)
You may want to make some test on your new explosive to deduce the ''force'' needed for initiation. for example, you can make many blasting cap
containing different amount of initiating explosive. by detonating several charge with these initiators (the charge are put on a witness plate for
detonation confirmation) you can deduce some information on the force needed for initiation. You can compare the result to another reference explosive
that you have tested with the same blasting cap. but you should keep in mind that the charges need to be carefully made, this mean all charges should
be the same (same loading density, confinement, granulometrie...) or your result will suffer from large errors leading to erroneous conclusion.

plasticized ETN with enough plasticizer to hold it together, (90% and 10%) but still no different texture or feel than gum already been chewed is
water proof and sensitive to a hammer strike.
