Perfluorocarbon Rubber

Perfluorocarbon Rubber, FFKM, is one of the most expensive synthetic rubber compounds produced. The mechanical properties are very similar to fluorocarbon rubber but it exhibits even greater resistance to aliphatic and aromatic hydrocarbons, esters, ethers, keytones, oils, lubricants and most acids. It is used in demanding applications for chemical processing, oil production and in the aerospace and aircraft industries.
