(Viton® is a DuPont Performance Elastomers registered name)
Available products: O-rings, Vulcanised joined cord rings, Washers, Gaskets, Sheet, Strip, Mouldings, Extrusion, Inflatable seals, O-ring cords
Fluoroelastomers (FKM/FPM) exhibit excellent resistance to petroleum products, low compression set and high temperature resistance, however the low temperature capability is restricted. Special formulations may be offered to enhance either the low or high temperature performance. The normal service temperature range is -20°C to +204°C.
