FIELD: chemistry.
SUBSTANCE: invention relates to a fluorine rubber based cross-linked elastomer composition used for manufacture of a rubber product. The composition comprises fluorine rubber, hydrophobic silicone dioxide, hydrophobically modified using hexamethyldisilazane or silicone fluid, organic peroxide as a cross-linking system, and an additional cross-linking agent. The composition contains 1 to 50 pts.wt. of hydrophobic silicone dioxide, 0.1 to 5 pts.wt. of cross-linking system, and 0,1 to 30 pts.wt. of an additional cross-linking agent per 100 pts.wt. of fluorine rubber.
EFFECT: invention provides reasonable hardness and elongation of the cross-linked material.
