Making Bakelite (Part 2)
Added 2017-04-19 23:57:02 +0000 UTCThis is the second part!
Let me know what you guys think of this project. If any of you guys think you have something that you can properly cure the novolac in, let me know!

I'm not sure. But I want to try to make as many commercial polymers as I can. So I'll look into epoxies

You need a small but strong pressure vessel, which you'd occupy a significant fraction of the interior volume of with the novolac or resol. This way the initial outgassing will serve to pressurize the vessel sufficiently to limit the subsequent bubbling. It would also need to be a slow process. Essentially reinventing the bakelizer. I have no idea what you could use off-the-shelf for this purpose, it'd need to be custom built I guess.

2017-04-21 18:33:46 +0000 UTCThe process you explored in these videos is really interesting. I might have a go at this synthesis as it would be interesting to explore alternative curing methods in detail... all assuming I have the time available. Many thanks for an inspiring and entertaining video.

I can imagine putting the paper and melted bakelite through some sort of press or rollers. That might take care of any bubbles in the p-f resin and press it into the pores in the paper. The better boards, those used in real consumer electronics , are woven fiberglass in an epoxy matrix. How hard is it to make epoxy resins?
