AUTOMOBILE INTERIOR PARTS MOLDED FORM

PROBLEM TO BE SOLVED: To provide an automobile interior part excellent not only in touch and product appearance by having flexibility, being nonsticky, and having advantageous mold grain transcription property, but also in damage resistance. SOLUTION: This automobile interior part is produced by hot-molding a propylene-ethylene block copolymer composition containing 20 to 90 wt.% of a propylene-ethylene block copolymer (component a) satisfying the requirements (i) to (v) below and 10 to 80 wt.% of a thermoplastic elastomer (component b) selected from an olefin-based elastomer and a styrene-based elastomer, and has characteristics 1 and 2 below. (i) Using a metallocene-based catalyst, there are sequentially polymerized in a first process, 30 to 95 wt.% of (A) a propylene homopolymer component or a propylene-ethylene random copolymer component and in a second process, 5 to 70 wt.% of (B) a propylene-ethylene random copolymer component, (ii) MFR is 0.5 to 200 g/10 min, (iii) a melting peak temperature (Tm) measured by the DSC method is 110 to 150°C, (iv) a molecular weight distribution (Mw/Mn) measured by the GPC method is 1.5 to 4, (v) a tanδ curve in a temperature-loss tangent curve has a single peak in a range of 0°C or less, (characteristic 1) a surface color difference between before and after the JSPS (Japan Society for the Promotion of Science)-type dyed thing color fastness to rubbing test is 3 or less, (characteristic 2) hardness A according to JIS K6301 is 95 or less.
