Replacement for Thermoset
(OP)
I'm looking for a replacement for Durez 31906 Black phenolic. My problem is the lack of dimensional stability, and wear resistance after molding - both of which I have to improve. I'm willing to look at other phenolics, or even other MATERIALS all together.
Thanks for any suggestions!

RE: Replacement for Thermoset
what kind of dimensional stability do you need and under what conditions-humidity, temperature?
what kind of wear?
thanks
RE: Replacement for Thermoset
Temperature is not a factor (the sliding action on this plate is at a very low velocity). Humidity can be an issue, but this part is not being loaded funtionally.
Thanks

Unfortunately if the plate is not supported correctly, under humidity and temperature variations, the plate will deform. How about a plastic top screwed into a metal back plate? Then you dont have to worry about warpage.
Or if you could take the molded part and have it "finish" machined. Take it to a machine shop and have them do some surfacing to square the planes.
Good Luck.

material offers high wear resistance & high load bearing strength. Tooling cost for building open cast molds are very low. There are numerous suppliers out there that will do a turn-key job for you
