Nuo gets Er balata (EPDM) polyester plays body (TPE) - - - - - - 80 degrees

Get together slant balata of propylene of fluorine ethylene fluorine (FPM) - - - - - - - - - - - - - 120 degrees

Iron fluorine dragon (PTFE) , silicon kind balata (TPO) - - - - - 100 degrees

(if use FPM diaphragm, its life is relatively other material is shorter)
