RESIN COMPOSITION AND AUTOMATIC INTERIOR MEMBER

Title:

RESIN COMPOSITION AND AUTOMATIC INTERIOR MEMBER

Document Type and Number:

Japanese Patent JPH10324725

Kind Code:

A

Abstract:

To obtain a new resin composition excellent in fluidity, and also in rigidity and impact resistance, etc., of a molded product by compounding a composition comprising a highly tough polypropylene/ethylene-propylene copolymer composition, ethylene-higher α-olefin copolymer rubber and talc with a hydrogenated diene block copolymer.

This composition has ≥25 g/10 min melt flow rate and is obtained by blending (A) 50-60 wt.% of a highly tough polypropylene/ethylene- propylene copolymer composition, (B) 5-40 wt.% of ethylene-higher α-olefin copolymer rubber, (C) 1-10 wt.% of a hydrogenated diene block copolymer and (D) 10-30 wt.% of talc. A molded product from the composition exhibits ≥2,400 MPa flexural modulus at a normal temperature, ≥73°C heat distortion temperature (under 1,820 kPa load) and ≥300 J/m Izod impact strength at a normal temperature.
