O-ring seal PF80E FEPM

fluoroelastomer

PF80E FEPM Series has different feature with PF80V，also has different applications. Basically the compositive monomer of PF80E is similar with PF80V，however，PF80E has more excellent molecular structure than PF80V，therefore the parts which mainly composed of PF80E are considered as： Adequate for low temperature environment Alkali resistance Ammonia resistance Acid resistance Adequate for high temperature environment Possible to be used instead of some FFKM material PF80E FEPM is a kind of chemical compound which made from peroxide Elastomer，the main difference between PF80E and PF80V is that PF80E FEPM contain E type protective monomer，the material made the chemical-resistance and the temperature tolerance of PF80E second to that of FFKM. The cost of PF80E is much cheaper than FFKM. Anyway, PF80E can only provide 70% chemical-resistance of FFKM, the users have to confirm the process before usage. FFKM may be over-spec. for some applications, in such case, PF80E FEPM is your best choice of low cost and high performance.
