ABSTRACT:
A silicone elastomer composition which has novel crosslinking points comprises (A) 100 parts by weight of a polyorganosiloxane of a polymerization degree of at least 20, wherein the organic groups are selected from monovalent substituted and unsubstituted hydrocarbon groups and are attached to silicon atom, and at least two of the organic groups are monovalent hydrocarbon groups possessing at least five carbon astoms and a carbon-carbon double bond bonded to a silicon atom via at least one carbon atom, (B) 5 to 200 parts by weight of an inorganic filler having a specific surface area of at least 50 m.sup.2 /g, and (C) 0.1 to 25 parts by weight of a vulcanizer selected from the group consisting of sulfur, sulfur donor, substituted or unsubstituted alkylphenol resins, and quinoids.
