ABSTRACT:
The invention provides a polyolefin-based rubber composition capable of giving a vulcanizate having excellent flame retardancy along with high mechanical strengths. The composition comprises: (A) 100 parts by weight of a polyolefin-based synthetic rubber, e.g. EPDM rubber; (B) 1 to 100 parts by weight of an organopolysiloxane; (C) 1 to 100 parts by weight of a bromine-containing flame retardant agent and/or red phosphorus; (D) 5 to 200 parts by weight of aluminum hydroxide and/or magnesium hydroxide; and (E) 0.5 to 20 parts by weight of zinc carbonate and/or manganese carbonate.
