Beschreibung
Zusammenfassung:	An addition-curable silicone rubber composition includes: (A) 100 parts by mass of alkenyl-group-containing organopolysiloxane having two or more alkenyl groups bonded to a silicon atom within one molecule; (B) 0.2 to 20 parts by mass of organohydrogenpolysiloxane containing two or more hydrogen atoms bonded to a silicon atom within one molecule; (C) catalytic amount of a platinum-based catalyst; (D) 0.01 to 5.0 parts by mass of thermally-dissociative blocked (poly)isocyanate; and (E) 0.01 to 10.0 parts by mass of a heat resistance-imparting agent. The addition-curable silicone rubber composition and silicone rubber cured material can produce a cured material having a low compressive set even under high temperature conditions of 200° C. or more.
