Creep testing of PEEK
Creep testing of PEEK
(OP)
Hi,
I am looking for data that can be used to design a valve seat made of PEEK 450g that will tell me what kind of compressive creep properties it has. I ahve not been able to find ASTM D2990 data for it. I am just trying to ensure that during our pressure proof test, we will not develop too much permanent set in the material. Test is about 48hrs at 20ksi compressive or seating stress.

Solvay may also have data.
