Alternatives to Santoprene
(OP)
We manufacture 2 small ( 14mm dia. and 55mm dia) diaphragms from 70 Sh A Santoprene. Both diaphragms act as high flow dump valves. Both dump valves open only 500 times over the entire life of the product. One side of the valve is exposed to 70 PSi with the other side to atmosphere. .Operating pressures are approx. 60-70psi.
We are finding that they are suffering from a greater degree of compression set than expected. Both are injection molded.
Can anyone suggest a alternative material with good CS characteristics that can be injection molded?
thanks..

I can't really be more specific without knowing what compression set value are you looking for- can you advise?
