Fluorosilicone rubber composition for use in sealing products, e.g. seals for collector tubes in contact with polyamide-6 resin, contains organopolysiloxane with trifluoropropyl and vinyl groups, plus silica filler and catalyst
Fluorosilicone rubber composition with silica filler and catalyst, contains an organopolysiloxane with trifluoropropyl groups, unsaturated aliphatic hydrocarbon groups and saturated aliphatic or aromatic groups attached to silicon. Fluorosilicone rubber compositions (I) containing 100 parts by weight (pts. wt.) organopolysiloxane of the following formula R 1aR 2bR 3cSiO (4-a-b-c)/2, plus 5-100 pts. wt. silica-based filler and a catalytic amount of hardening catalyst. R 1trifluoropropyl; R 2optionally substituted 2-8C unsaturated aliphatic hydrocarbyl; R 3unsaturated saturated aliphatic hydrocarbyl or aromatic hydrocarbyl with 1-8 carbons; a : 0.96-1.01; b : 0.002-0.02; c : 0.96-1.06; (a+b+c) : 1.98-2.02 . An independent claim is also included for rubber sealing products made from hardened material (I).
