PURPOSE:To provide a rubber compsn. having excellent flame retardance and resistance to low temperature and oils, by adding a specified compd. to a rubber component mainly composed of an acrylonitrile/butadiene copolymer. CONSTITUTION:5-40pts.wt. (halogenated) phosphate such as trimethyl phosphate or tris-(chlorethyl) phosphate, 10-60pts.wt. chlorinated polyethylene and 2- 10pts.wt. antimony trichloride are blended with 100pts.wt. rubber component consisting of at least 70wt% acrylonitrile/butadiene copolymer rubber having a nitrile content of 15-30wt% and not more than 30wt% polybutadiene rubber.
