It has excellent heat resistance, aging resistance, oil resistance, ozone resistance and UV resistance. The mechanical properties and processability are superior to FKM and silicone rubber, and its heat resistance, ageing resistance and oil resistance are superior to NBR. It is widely applied to various high temperature, oil resistant environment and in recent years it becomes a kind of sealing material which is mainly developed and promoted in the automobile industry, especially for motor vehicles’high temperature resistant oil seal, valve rod, crankshaft, cylinder pad, hydraulic oil pipe and so on.
