High Temp Silicon

[Spin Doctor]

Over the Holidays I picked up some of those soft Silicon Rubber Baking pans. I wonder if the silicon material is available for making molds with this stuff. Seems to be it would be ideal for making molds for doing lost wax castings. Anyone know a source?

I hate to be a "nit picker" but silicon is a semimetalic element as transistors
etc. It is not something that goes with rubber. You mean silicone a different
thing altogether. ( I only know what you said not what you meant ) :-)

Yeah

When I read the thread title I thought he wanted to know about stuff like down hole drill bit monitoring equipment. They have silicon carbide transistors that can run at molten solder temps.

I guess they need to add a Spell Check function to the BBS

Spin, you don't need special high temp rubber to cast the wax masters. I've made & used many loxt wax patterns made of just standard molding rubber..

Do a GOOGLE on "liquid rubber" and you will get many web sites which offer specs/suggested uses/sales of many kinds of molding rubber. SOme even have how to vidios.

If you want to support the small business owner I've done business with this guy before. Most places I found sell five gallon bucket fulls but you can buy as little as five pounds from him. No affiliation of course.
