<p>An interior automotive trim part that even when the amount of thermoplastic resin used is reduced, does not suffer moldability deterioration, and that is lightweight and has appropriate rigidity. Panel (1) of hollow double-wall structure constituting an interior automotive trim part is formed of a polyolefinic resin mixture consisting of propylene homo/copolymer (A) of = 0.93 specific gravity (JIS K7112), 0.3 to 3.0 g/10 min melt flow rate (JIS K7210) and = 1400 MPa flexural modulus (JIS K7171), crystalline propylene block copolymer (B) of = 0.93 specific gravity (JIS K7112), 0.3 to 1.5 g/10 min melt flow rate (JIS K7210) and = 1250 MPa flexural modulus (JIS K7171) and high-density polyethylene (C) of 0.925 to 0.965 specific gravity (JIS K7112) and = 0.5 g/10 min melt flow rate (JIS K7210).</p> |
