Title:
CRYSTALLINE RESIN, CRYSTALLINE RESIN COMPOSITION, AND INJECTION MOLDED ARTICLE USING SAME, AND METHOD OF INJECTION MOLDING
Document Type and Number:
Japanese Patent JP2005281578
Kind Code:
A
Abstract:
To provide an optimum crystalline resin or a crystalline resin composition producing few flow marks, and to provide an injection molding method.
The crystalline resin for injection molding has a shear rate of r≤15 (1), wherein r is a characteristic shear rate of the crystalline resin at the injection molding temperature of 200°C whereat the first normal stress difference N1 is equal to the shear stress σ. The polypropylene resin composition for injection molding comprises (A) a crystalline resin, (B) an elastomer, and (C) an inorganic filler.
