FFKM

The fluorine rubber is composed of TFE (backbone), PMVE (branched) formed and bridging part, it not only has high temperature resistant and excellent properties like PTFE, resistance to chemical corrosion (corrosion resistant to more than 1600 kinds of chemicals), also has the elasticity of the rubber, which at 300 ℃ compression deformation rate is only in 50% the following. Ordinary full fluorine rubber working temperature range is -25 ℃ ~ + 240 ℃, perfluoroelastomers Tetlock high temperature up to 327 ℃, even when exposed to constant temperature of 316 ℃ or 343 ℃ like intermittent high temperature environment, Tetlock company's products will not cause hardening and embrittlement of seal failure still, can maintain its elasticity and resilience in the impregnation and corrosive fluid or direct contact. In fact, thermal stability and perfluoroether are often more than the fluid itself. Full of fluoroether rubber has excellent air tightness (high vacuum degree up to 1.33X10-7 - 1.33X10-8Pa) and the Gao Jie net resistance and plasma, these characteristics used in the semiconductor industry is very extensive, because the semiconductor industry requires the use of many rare and corrosive chemical products production silicon circle. Occasions perfluoroelastomers is commonly used in the chemical industry and the corrosive medium gap at high temperature.

It is precisely because of these excellent characteristics, can not be replaced, making perfluoroether products widely used in: chemical, petroleum, machinery manufacturing, aviation, aerospace, military equipment, electronic instrumentation, semiconductor equipment, shipbuilding and various types of vehicles, can meet a lot of harsh conditions for.
