Phenolic Resin: Where can an individual get this?

So, I've been trying to make some vitreous carbon. It's an extremely useful material. After searching through patents, I found several that described processes for making it through pyrolysis of phenolic resin. When I saw that, I thought, "yay! phenolic should be easy enough to get! That's just bakelite!"

Oh how wrong I was. . .

Basically, I have not been able to find ANYWHERE that sells this in sane quantities. Every producer of it has a "get a quote" button, which is basically a euphemism for "too expensive for you."

Any help?

Most printed circuit boards use phenolic resin as a substrate IIRC.



As below, so above.

Lots of stuff made from it on ebay, alternatively you could try to make your own.

Go to any thrift store and buy old outlet plates and grind them up. Or go to Home Depot and buy a multipack, but make sure that they are the hard thermoplastic type, not the newer flexible ones, which are not bakelite. But older ones were all bakelite. The Habitat reuse stores usually have scads of them.

The nasty old brown ones do. The resin is soaked into paper sheets and loaded with fire retardants. New ones are epoxy fiberglass sheets.

The problem is that bakelite was impregnated with wood flour as a filler, wouldn't that interfere with the pyrolysis process? Obviously cellulose and lingnin are primarily carbon, but their pyrolysing behavior might be rather unpredictable.
