FFKM/FFPM is a copolymer of tetrafluoroethlene and perfluroalkyl vinyl ether , widely used in high quality sealing production. Due to the elimination of fillers in the structure of the polymer, sealing made of perfluroelastomer rubber FFKM/FFPM have increased resistance to acids, alkali, Ketones, Ethers, Alcohol, Ester, Aldehydes, Hydrogen carbide, Nitrogen compounds, and Amino compounds--etc.
What is more, their low permeability also means lower swelling tendency and because of that such sealing may have longer service live. Moreover, they have low permanent deformation rate while pressing, also in the environment of highly aggressive chemicals and in very high temperatures.
FFKM/FFPM Perfluroelastomer rubber is used in:
★ petroleum industry
★ chemical/chemistry industry
★ pharmaceuticals industry
★ aerospace industry
★ nuclear power industry
★ semiconductor industry used in CVD, LPCVD, PECVD, LDCVD process
