PURPOSE: To provide the titled compsn. which does not cause melt snagging during flame retardation and has excellent electrical insulating properties and mechanical characteristics, by blending a bromine-containing flame retarder, Sb 2 O 3 , an olefin elastomer, a lead compd. and fumed silica with a polyolefin resin. n CONSTITUTION: 100pts.wt. polyolefin resin (A), 5W50pts.wt. decabromodiphenyl ether (B), 3W30pts.wt. olefin elastomer (C) (e.g., an ethylene-propylen elastomer), 1W20pts.wt. lead compd. (E) (e.g., lead stearate), 1W20pts.wt. fumed silica (F) and, if necessary, not more than 5pts.wt. org. peroxide are mixed together to obtain the titled compsn. For example, said compsn. is extrude onto a cable conductor to cover it and then crosslinked to form an insulating layer. n COPYRIGHT: (C)1981,JPO&Japio |
