Product Details

The chemical resistance of Perfluoroether Rubber (FFKM) is similar with PTFE that can resist almost chemical liquids and gases, such as: organic acids, inorganic acids, alkaloids, ketones, ethers, amines, organic solvents. Except the excellent chemical properties, FFKM also has the flexibility, excellent heat resistance and cleanliness. Instant heat resistance is 350.

For some special industries, the loss caused by abnormal downtime is much greater than the maintenance of parts and manpower costs. Perfluoroether rubber products can effectively help users improve the stability of the process to extend the working hours of equipment for customers to obtain more benefits.

FFKM (Perfluoroelastomer) is the best elastomer of high temperature resistance and chemical resistance for sealing. FFKM can resist chemicals and corrosive medium including strong acid, strong base, ethers, ketones, esters, nitrogen-containing compounds, hydrocarbons, alcohols, aldehydes, oils, steams, amino compounds and more than 1,600 kinds of chemical products. FFKM can resist the high temperature of 330, and instant heat resistance is 350.

Our FFKM have replaced Dupont Kalrez, Green Tweed Chemraz, Perlast PPE, Trelleborg Isolast and Daikin Dupra successfully.
