Product Description:The YT? PF80E FEPM O-ring is a compound made from a non-wheelmark fluoroelastomer series, using peroxide elastomer as the base material. The key difference from the YT? PF80V O-ring lies in the protective monomer used for the YT? PF80E FEPM O-ring, which is E. It offers chemical resistance and temperature resistance second only to FFKM, with significantly lower costs in application compared to FFKM. However, its chemical resistance is only 70% that of FFKM, so environmental conditions must be verified before use to ensure smoother operation.In environments with excessive demand for FFKM, the YT? PF80E FEPM O-ring is a cost-effective, high-efficiency alternative.Basic properties of the YT? PF80E FEPM series:? Suitable for low-temperature environments? Strong resistance to alkalis? Strong resistance to ammonia? Excellent acid resistance? Suitable for high-temperature environments? Can replace some perfluoroelastomers more>
