ABSTRACT:
The invention provides a highly flame-retardant polyolefin-based rubber composition free from the problem of the formation of toxic or corrosive gases and a large volume of smoke by burning of conventional flame-retardant rubber compositions impregnated with a large amount of a halogen-containing flame retardant agent. The inventive rubber composition comprises (a) a synthetic rubber of polyolefin type, (b) an organopolysiloxane resin which is preferably formed of monofunctional siloxane units and tetrafunctional siloxane units in a molar ratio of 0.6/1.0 to 2.0/1.0, (c) red phosphorus and (d) aluminum hydroxide or magnesium hydroxide in a specified proportion.
