Fluorine Content: 70% Packing: PE plastic bags and cartons Net Weight: 20KG Storage:Store in a cool and shady place. Transportation: Non-dangerous goods, keep away from pollution source, sunshine and water during transportation.
High fluorine-content FKM(70%) are the terpolymer of vinylidenefluoride,tetrafluoroethylene and hexafluoropropylene.Because of its high fluorine content,its vulcanized rubber has excellent anti oil property and high thermal stability.It also has good mechanical property and can be used in 275℃ for a long time,in 320℃ for a short time.The property of antil oil and anti acid is better than FKM Copolymer,resistance of High fluorine-content FKM to oil,ozone,radiation,electricity and flamer is similar with FKM Copolymer.
High fluorine-content FKM exhibits superior properties compared to standard FKM due to its increased fluorine content, which enhances chemical resistance, thermal stability, and sealing performance.

High Fluorine-content FKM is widely used in automotive, machinery, petrochemical, and other industries. For example, it serves as a static and dynamic sealing material in the hydraulic and lubrication systems of aircraft. In the oil and gas sector, it is used in drilling equipment and oil pipelines. In the chemical industry, High Fluorine-content FKM is applied in equipment components, flexible pipe connections, pump liners, and corrosion-resistant sealing materials. Additionally, it is used to manufacture pipes for transporting solvents or other corrosive media.
