|
FKM Fluorine rubber |
Hear resistant,acid and alkali resistant and chemicals, oil resistance preferred | -20~200 |
|
VMQ Silicone rubber |
Heat and cold resistance, good compression deformation is small, but the mechanical strength is not good | -60~230 |
|
ACM Polypropylene acid ester rubber |
Heat resistance, oil resistance better than NBR, but resistance to water and alkali is not strong | -20~150 |
