FFKM diaphragms resist strong acids, ethers, esters and other aggressive chemicals with excellent high-temperature chemical resistance, widening the application envelope of high-end equipment and extending maintenance intervals.
An FFKM diaphragm takes a diaphragm pump or valve into media that would destroy any other elastomer — strong acids, ethers, esters and amines at high temperature. The practical effect is a wider application envelope for the equipment and longer intervals between maintenance.
