FIELD: synthetic rubbers.
SUBSTANCE: invention relates to composition based on fluorosiloxane rubber (100 wt parts), which composition further includes 25-35 wt parts silica filler, 5-10 wt parts polyorganosiloxane liquid, 0.5-0.2 wt parts organic peroxide, and additionally 5-10 wt parts iron oxide, said fluorosiloxane rubber being, in particular, poly(methyl-3,3,3-trifluoropropylmethylvinyl)siloxane rubber having molecular weight 900-1500 and molar portion of methylvinylsiloxane units 0.15-0.25 mol %, and said polyorganosiloxane liquid being diorganodialkoxysilane.
EFFECT: increased oil and fuel resistance of composition, which allows lifetime of technical rubber parts in immovable and restrictedly movable connections in air, fuel, and lube oil media to be considerably increased.
