耐高温耐腐蚀FFKM全氟醚O型密封圈厂家规格价格
Perfluoroelastomers are used when a wide range of chemical resistance and high temperature resistance are required. Perfluoroelastomers are used if the chemical industry, oil and gas recovery, semiconductor processing, pharmaceutical and aerospace industries.
Perfluoroelastomers are a terpolymer of perfluoromethylvinyl ether (PMVE), tetrafluoroethylene (TFE) and a cure site monomer (CSM). With perfluoroelastomers the hydrogen atoms have been replaced with fluorine. The strong bond between the fluorine and the carbon atom is what makes this 企业pound so chemically resistant and strong. Also there are no double bonds in the back bone of the molecule which leaves no place for ozone, UV light, oxygen and harsh chemicals to attack and break down the molecule
