FKM (Viton) –JX-2460 series are the terpolymer of VDF, TFE and HFP. 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 anti oil and anti acid is better than F23, resistance of FKM-246 to oil, ozone, radiation, electricity and flamer is similar with FKM-246.
