Title:
NON-HALOGEN FLAME-RETARDANT RESIN COMPOSITION, AND ELECTRIC WIRE AND CABLE WHICH ARE MADE USING SAME
Document Type and Number:
WIPO Patent Application WO/2011/129129
Kind Code:
A1
Abstract:
Provided is a non-halogen flame-retardant resin composition which exhibits excellent mechanical strengths (such as flexibility and wear resistance), excellent flame retardance, particularly excellent cut-through characteristics, and tensile elongation characteristics satisfying the UL standards. Also provided are an electric wire and a cable which are made using the resin composition as a cover layer. A non-halogen flame-retardant resin composition which comprises 100 parts by mass of a resin component and 5 to 40 parts by mass of a phosphorus-based flame retardant, wherein the resin component comprises 30 to 85 parts by mass of a polyolefin resin, 10 to 50 parts by mass of a polyphenylene ether resin, and 5 to 30 parts by mass of a styrene-based elastomer, each content (parts by mass) being relative to 100 parts by mass of the resin component, and the polyolefin resin comprises 5 to 60% by mass of an ethylene/propylene random copolymer obtained by polymerization using a metallocene catalyst and 30 to 95% by mass of a block-copolymerized polypropylene resin, each percentage being relative to the whole polyolefin resin.
