Document Type and Number:
WIPO Patent Application WO/2023/276628
Kind Code:
A1
Abstract:
The present invention provides an addition-curable silicone rubber composition which is characterized by containing: 100 parts by mass of (A) an alkenyl group-containing organopolysiloxane that has an alkenyl group bonded to two or more silicone atoms in each molecule; 0.2 to 20 parts by mass of (B) an organohydrogen polysiloxane that has two or more hydrogen atoms, each of which is bonded to a silicon atom, in each molecule; a catalytic amount of (C) a platinum-based catalyst; 0.01 to 5.0 parts by mass of (D) a thermally dissociative blocked (poly)isocyanate; and 0.01 to 10.0 parts by mass of (E) a heat resistance imparting agent. Consequently, the present invention provides: an addition-curable silicone rubber composition which enables the achievement of a cured product which has a low compression set even under high temperature conditions of 200°C or more; and a cured silicone rubber product.
