electric wires and cables halogen-free flame-retardant resin composition and using the same

摘要

Excellent flame retardancy and mechanical strength flexibility and wear resistance, and excellent in cut-through properties, particularly, the flame-retardant resin composition and a non-halogen flame retardant resin composition having a tensile elongation characteristics to meet the UL standard I provide the wires and cables that were used as the coating layer things. A non-halogen flame-retardant resin composition 5 to 40 parts by mass of a phosphorus flame retardant per 100 parts by mass of the resin component, 30 to 85 parts by weight of polyolefin resin, polyphenylene ether in 100 parts by mass of the resin component 10 to 50 parts by weight of the resin system, and contains 5 to 30 parts by mass of styrene-based elastomer, wherein the polyolefin resin is ethylene is polymerized using a metallocene catalyst - 5 for the polyolefin resin throughout the propylene random copolymer 60 mass%, and contains 30 to 95 mass% based on the entire polyolefin resin block copolymer polypropylene resin.
