Abstract: The present invention relates to a poly(arylene ether) resin composition and a cable coated with the same. More particularly, the present invention relates to a poly(arylene ether) resin composition, including 20 to 40% by weight of a poly(arylene ether) resin, 15 to 35% by weight of a low-molecular weight styrene-based block copolymer having a weight-average molecular weight of 90,000 g/mol or less, 10 to 30% by weight of a high-molecular weight styrene-based block copolymer having a weight-average molecular weight of 95,000 g/mol or more, 1 to 20% by weight of a flame retardant, and 0 to 20% by weight of an additive.In accordance with the present invention, a poly(arylene ether) resin composition having superior flame retardancy, tensile strength, flexibility, extrusion processability, elongation, and appearance characteristics and a cable coated with the same are provided.

Abstract: The present invention relates to a non-halogen thermoplastic resin composition and a cable including the same. More particularly, the present invention provides a non-halogen thermoplastic resin composition in which a halogen-based flame retardant causing environmental and human health problems is not included and the content of a phosphorus flame retardant causing decrease in appearance and properties is decreased, but which has identical or superior mechanical strength, chemical resistance, heat resistance, and flame retardancy, compared to existing thermoplastic resin compositions, and a cable including the same.

Abstract: The present invention relates to a polypropylene resin composition and a cable cladded with the same. More particularly, the present invention relates to a polypropylene resin composition, including 25 to 35% by weight of a polypropylene polymer, 15 to 25% by weight of a styrene block copolymer, 15 to 25% by weight of a poly(arylene ether) resin, 26 to 35% by weight of a phosphorus flame retardant, and 0 to 10% by weight of a processing additive.In accordance with the present invention, a polypropylene resin composition including a small amount of flame retardant but exhibiting excellent flame resistance, insulation performance, processability, and property balance, and a cable cladded with the same are provided.
