A FKM Compound Having Improved Wear Resistance For Seal

摘要

In the present invention, 60 to 70% by weight of a polymer made of fluorine rubber, 10 to 20% by weight of the first carbon black (MT), 8 to 20% by weight of an inorganic filler, and 1 to 3% by weight of a crosslinking agent are mixed; The second carbon black further comprises 1 to 5% by weight, and the second carbon black has a surface area per unit mass (m 2 /g; BET) in the range of 80 to 83, and the PAH content is more than 0 ppm and less than 5 ppm. It relates to a fluororubber composition for seals having improved wear resistance.
