Features of Perfluoroelastomer O-Rings FFKM :

Perfluoroelastomer(FFKM) is a revolutionary product and has theperformance of elasticity, heat resistance and purity, more excellent than Teflon and normal rubber. In the aspect of chemical resistance, general Vitoncan’t 
adapt to the environment of etherate, amido compound, ketone, oxidant, strong acid & alkaline, fuel, cid 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 provided with the advantages of extend sealing life, reduce maintenance cost and degrade pollution.

Application of Parameters of Perfluoroelastomer O-Rings FFKM :
 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 oil,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’s widely used in semiconductor manufacture
