Piston Seal FKM

Viton 23 is a copolymer of vinylidene fluoride and trifluoroethylene, commonly known as No. 1 rubber in China.
Fluorine rubber 26 is commonly called No. 2 rubber in China, DuPont brand fluorine rubber a, which is a copolymer of vinylidene fluoride and hexafluoropropylene, and its comprehensive performance is better than No. 1 rubber.
Fluoroelastomer 246, commonly known as the third largest rubber in China, DuPont Brand Fluoroelastomer B, is a terpolymer of vinylidene fluoride, tetrafluoroethylene and hexafluoropropylene, with fluorine content higher than 26 and good solvent resistance.
Fluoroelastomer TP, commonly known as tetrapropylene rubber, Asahi brand aflas, is a copolymer of tetrafluoroethylene and propylene hydrocarbons, which has excellent resistance to water vapor and alkali.
Vinylidene fluoride rubber, DuPont brand fluororubber, is a quaternary copolymer of vinylidene fluoride, tetrafluoroethylene, perfluoromethyl vinyl ether and vulcanization point monomer, with excellent low-temperature performance.
Perfluoroether rubber, DuPont Karez, has excellent high temperature resistance, high fluorine content, and excellent solvent resistance.
Fluorosilicone rubber has excellent low temperature performance and certain solvent resistance.
Fluoroelastomer is mainly used in automobile and automobile industry. It is mainly used for Oil Seal and O-Ring due to its excellent high temperature resistance, oil resistance and medium resistance.
