THERMOPLASTIC POLYURETHANE RESIN COMPOSITION FOR PLATED DUAL MOLDING, DUAL-MOLDED PRODUCT FOR PLATING, PLATED DUAL-MOLDED PRODUCT, AND METHOD FOR PRODUCING THEM

摘要

PROBLEM TO BE SOLVED: To provide a thermoplastic polyurethane resin composition for plated dual molding to obtain a dual-molded product for plating, which consists of a first molded body formed of a hard resin and a second molded body formed of a soft resin and exhibits sufficient plating processing resistance since discoloring by plating processing is sufficiently suppressed in the molded body formed of the soft resin.

SOLUTION: The thermoplastic polyurethane resin composition for plated dual molding comprises an organic diisocyanate (A) principally consisting of a hexamethylene diisocyanate (a1), a high polymer polyol (B) principally consisting of a polycarbonate diol (b1), and a chain extender (C) principally consisting of a 2-10C aliphatic diol (c1).
