Rock Metal offers a wide selection of sealing materials in silicon carbide, carbon graphite, tungsten carbide, ceramic, rubber and stainless steel, etc. View our variety of sealing types equipped to handle the vast majority of sealing solutions and available for nearly all applications.

Perfluoroelastomer (FFKM) is synthetic elastomer, without C-H linkage. This kind of rubber, which can effectively work under the max temperature of 327℃ and bear corrosion of any chemical mediator, has perfect tolerance to oi, chemical & heat. Fluorocarbon linkage is the main reason to high stability performance. The refractory compression permanent deformation performance of Perfluoroelastomer is superior to that of viton.

It is widely used in semiconductor manufacture, petrochemical, gas extraction, medical food and aerospace industries because of the champion nature.

Perfluoroelastomer (FFKM) is a revolutionary product and has the performance of elasticity, heat resistance and purity, more excellent than Teflon and Normal rubber.

In the aspect of chemical resistance, general viton can’t adapt to the environment of etherate, amido compound, ketone, oxidant, strong acid & alkaline, fuel, acid and alkaline, but Perfluoroelastomer shows the excellent stability and perfect tolerance to all kinds of chemical mediator. In the other aspect of heat resistance, Perfluoroelastomer can keep the performance of elasticity, be probided with the advantages of extend sealign life, reduce maintenance cost and degrade pollution.
