What is FFKM?
FFKM is perfluoroelastomer. The figure shows the chemical formula of FFKM as well as Teflon (PTEE: polytetrafluoroethylene) and viton, the fluorinated plastics containing higher amounts of fluoride. It is known to all that the fluorinated plast

What is rubber?
The word “Rubber” refers to the material derived from the rubber tree originally; however, it refers to the material having large deformability and certain resilience after elimination of the deformation force in now days. Currently, those syn

Characteristics of FFKM
FFKM is perfluoroelastomer. KTSEAL has successfully developed KTseal R, the first national perfluoroelastomer special for high technology in 2000. In addition to the same superior chemical resistance with Teflon and viton, KTseal R’s heat resist

Rubber material defined based on performance
In Table 1, the rubber classification “Type” and “Category” are determined according to ASTM D2000 and SAE J200. The determination of “Type” is based on thermal test for the purpose of determining the max. application temperature; the let
