Suitable material for gasket application
Suitable material for gasket application
(OP)
Hi all,
I'm a bit stumped on selecting a material for a gasket application with the following requirements:
1. Fireproof (in installation condition) according to AC 20.135
2. Compressible up to 30% of thickness without cracking
3. Thermal conductivity: 0.16 to 0.19 W/(m.K)
4. Maxiumum temperature: 535degC (995degF)
The closest material I've found is a variant of Thermiculite, but unfortunately these gaskets need to either be machinable or able to be layered up to 6mm thick. I know with Thermiculite they glue the layers together with Spraymount which isn't particularly suitable in the condtions required.
Thank you in advance for you advice and help.
Kind Regards,
Rachael.

Thanks very much for your reply - I actually work for a silicone business and even the best compound is only good for around 320degC continuous use, even with fabric/pulp reinforcement.
Thanks very much for you suggestion though.
Kind Regards,
Rachael.

Of course might need special testing to comply with your other requirements.

Could you use a metal O-ring?
