Hello,

I need to design a valve. Seat material POM.
Operating temperature is 80°C (176°F). I need the yield strength or compression strength... at least any strengh value for calculating the surface pressure.
at elevated temperatures. I only find ambient temp. values.

Anybody knows where to find that information?

THANKS!
 
Fit an Arrhenius curve to the three values listed and extrapolate it. That should be fairly accurate as long as you don't cross a transition temp, which you shouldn't be doing anyway if you want the seat to perform properly.
