rubber as a pressure barrier

rubber as a pressure barrier

(OP)
I'm looking for information regarding using different grades of rubber as a barrier over a pressure differential.

I'm thinking of it being used in an autoclave, so we're talking a bout a 20/30 psi differential @ ~120c for 20-60 minutes.

I feel like I'm reaching into an academic realm, but can't seem to find any info.

Any leads for me to chase are appreciated.

What's the environment- steam +?

gravity autoclave...

Downward displacement (or gravity type) - As steam enters the chamber, it fills the upper areas as it is less dense than air. This compresses the air to the bottom, forcing it out through a drain. Often a temperature sensing device is placed in the drain. Only when air evacuation is complete should the discharge stop. Flow is usually controlled through the use of a steam trap or a solenoid valve, but bleed holes are sometimes used, often in conjunction with a solenoid valve. As the steam and air mix it is also possible to force out the mixture from locations in the chamber other than the bottom.

EPDM in a high durometer (70+) may work.

It is true to say that higher durometer EPDM's generally have better tensile strength.
