发明名称 Polypropylene resin molding composite for automobile
摘要 A foam layer can be formed at a temperature at which the surface quality of a surface layer is not deteriorated, and a molding technique that is excellent in adhesiveness of a foam layer and a surface layer or/and a base member is developed. For the purpose of obtaining a polypropylene resin molding composite for automobile, the present invention is characterized by a polypropylene resin molding composite for automobile comprising a surface layer and a foam layer, or a surface layer, a foam layer, and a base member, wherein the surface layer comprises a surface layer of a polypropylene resin and a laminate of a cushioning material, where the cushioning material is a polypropylene resin expanded sheet, and the foam layer comprises thermoplastic resin expanded particles comprising a core that is made of a polypropylene resin and is in an expanded state and a polyethylene resin coat layer covering the core and is in a substantially non-expanded state.
