摘要 |
An interior article for automobiles is provided having a light-weight and suitable rigidity without lowering moldability even if the amount of use of a thermoplastic resin is decreased. A panel having a hollow double-wall structure and constituting an interior part for automobiles is formed from a mixture of polyolefin resins comprised of a propylene homopolymer having a specific gravity of 0.93 or less (JIS K7112), exhibiting a melt flow rate of 0.3 to 3.0 g/10 minutes (JIS K7210) and exhibiting a bending modulus of 1400 MPa or more (JIS K6758), a crystalline propylene block copolymer having a specific gravity of 0.93 or less (JIS K7112), exhibiting a melt flow rate of 0.3 to 1.5 g/10 minutes (JIS K7210) and exhibiting a bending modulus of 1250 MPa or less (JIS K7171) and a high density polyethylene having a specific gravity of 0.925 to 0.965 (JIS K7112) and exhibiting a melt flow rate of 0.5 g/10 minutes or less (JIS K7210). |
