Aflas is a fluororubber based on an alternating copolymer of tetrafluoroethylene and propylene tetrafluoropane rubber. Comnon name is FEPM according to ASTM D 1418. Which is very different from the well-known fluorine rubber FKM.
Aflas fluororubber has excellent durability to akali and amines due to its molecular structure. And at the same time, it has heat resistance and electrical insulation. Since it is also excelent in water vapor resistance, it can be used in applications where other fluorine rubber FKM can not be used.
Aflas fluororubber is used in petroleum, nature gas, chemical industry, pharmaceutical, food,diesel and auto industry.
