RESIN COMPOSITION, METHOD OF MAKING IT AND ELECTRICAL WIRE COVERED WITH IT |
摘要 |
A resin composition contains (a) 40-90 parts by weight of a block copolymer of polypropylene segments and ethylene-propylene copolymer segments which is modified with an acid anhydride, in which the polypropylene segment content is in the range 5 to 50 wt %, (b) 60-10 parts by weight of a styrene-based polymeric elastomer, or a styrene-based elastomer modified with an acid anhydride, and (c) 30-200 parts by weight of a metal hydroxide per 100 parts by weight of (a) and (b). This wear resistant halogen-free resin composition has high mechanical strength and flexibility and is suitable for extruding as an electrical wire covering for example for a wire used in an automobile.
