Abstract

The present invention offers a resin composition for user as a covering material for wires and cables that excels in fire retardancy with non-halogen, chemical resistance and melting properties, and also excels in workability, heat resistance, impact resistance and flexibility. A resin composition for wires and cables covering material is obtained by blending polyphenylene ether resin with syndiotactic polystyrene polymer, atactic polystyrene resin and non-halogen fire retardant or blending polyphenylene ether resin with syndiotactic polystyrene polymer, atactic polystyrene resin, non-halogen fire retardant and thermoplastic elastomer in fixed ratios.

Claims (6)

1. A resin composition consisting essentially of: (A) 10 to 70 parts by weight polyphenylene ether, (B) 15 to 75 parts by weight syndiotactic polystyrene polymer, (C) 10 to 40 parts by weight stactic polystyrene resin, (D) 5 to 40 parts by weight non-halogen fire retardant wherein the sum of components (A)+(B)+(C)+(D)=100 parts by weight, and (E) hydrogenated styrene block copolymer in an amount of 10 to 200 parts by weight with respect to 100 parts by weight of resin composition wherein the hydrogenated block copolymer has a molecular weight distribution below 10 and the composition has a tensile strength greater than or equal to 34 and a tensile elongation greater than 5 when determined according to ASTM D638.

2. The resin composition of claim 1 , wherein the polyphenylene ether component is poly(2,6-dimethyl-1,4-phenylene)ether having intrinsic viscosity in the range of 0.08 to 0.60 dl/g when measured in chloroform at 30° C.

3. The resin composition of claim 1 , wherein the non-halogen fire retardant is an aromatic phosphoric ester.

4. The resin composition of claim 1 , wherein the hydrogenated styrene-block copolymer is a block copolymer of styrene and butadiene or styrene and isoprene.

5. A wire covering made from the resin composition of claim 1 .

6. A cable covering made from the resin composition of claim 1 .
