Method of using polypropylene resin composition for deformation recovery structure and deformation recovery structure

摘要

PROBLEM TO BE SOLVED: To provide a method for manufacturing a deformation recovery structure using a polypropylene resin composition excellent in deformation recovery property under high temperature and a deformation recovery structure using the polypropylene resin composition.SOLUTION: There is provided a method for using a polypropylene resin composition (Z) containing a β crystal nucleus agent (B) of 0.001 to 2 pts.wt. based on 100 pts.wt. of a polypropylene resin composition (Y) containing a polypropylene resin composition (X) consisting of one or more kind of propylene polymer selected from a group consisting of a propylene single polymer, a propylene-α-olefin random copolymer and a propylene-α-olefin block copolymer for manufacturing a deformation recovery structure.SELECTED DRAWING: None
