Perfluoroelastomer Rubber
Perfluoroelastomers (FFKM) rubbers fill an important niche for applications involving aggressive chemicals at temperatures up to 300°C.
They are extremely expensive and have poor physical properties and limited use at low temperatures.
Typical applications include accumulator bladders, core sleeves, gaskets, O-rings and seals working in extremely harsh environments, particularly within the oil and gas industries.
