Scope Of Application

Very excellent chemical resistance, acid, alkali, ketone, ester, ether, strong oxidant and other chemicals. The highest heat resistance can be up to 330 degrees centigrade. A sealing problem that is usually used for extreme conditions.

Physicochemical properties: kalrez (FFKM) by TFE (backbone), PMVE (branched) and a bridge portion, it is not only like PTFE excellent high temperature resistance, chemical corrosion (corrosion resistant to more than 1600 kinds of chemicals), also has the elasticity of rubber, which at 300 DEG C when the compression rate is only 50%. Ordinary perfluoroelastomers operating temperature range of -25 DEG ~+240 DEG FFM, high temperature can reach 330 degrees, even when exposed to a constant temperature of 316 DEG C or the like 343 degrees of intermittent high temperature environment, FFKM production does not occur to harden seal failure and embrittlement, FFKM direct contact in the impregnation and erosion of flow the body still retains its elasticity and resilience. In fact, the thermal stability of FFKM is often more than that of the fluid itself. Perfluorinated rubber also has excellent air tightness (resistance to vacuum up to 1.33X10-7-1.33X10-8pa) and the Gao Jie net resistance and plasma, the characteristics of the application in the semiconductor industry is very extensive.

Temperature range: - 25 C to 240 C, resistant to high temperature up to 330 FFKM
