RESIN MOLDING INCORPORATING WOOD POWDER

摘要

PROBLEM TO BE SOLVED: To provide a product incorporating wood powder which can be molded even in a shape with a wall thickness difference and can flexibly meet the various shapes as a member to be used in various applications. SOLUTION: A molding has a substrate part and a surface layer part covering at least a part of the circumference of the substrate part. The substrate part is composed of a woody thermoplastic resin mixture comprising 20-50 mass% of a polyolefin resin and 50-80 mass% of the wood powder. The surface layer part is composed of a thermoplastic resin mixture comprising≥70 mass% of the polyolefin resin and≤30 mass% of the wood powder. The melt slipping of the woody thermoplastic resin mixture forming the substrate part which is measured in conditions of 180°C and shearing stress of 1×105to 5×105MPa is made 50-90% in slipping velocity ratio.
