POLYPROPYLENE RESIN COMPOSITION

摘要

PURPOSE: A polypropylene resin composition is provided to ensure excellent transparency and heat resistance and environment-friendliness since the emission of environment hormone is low, and to improve flexural strength and rigidity of end-products. CONSTITUTION: A polypropylene resin composition comprises: a high cubic regular polypropylene polymer in which stereoregularity is 96% or greater based on a pentard method by a nuclear magnetic resonance method; and a bis 4-propylbenzylidene propyl sorbitol nucleating agent. The bis 4-propylbenzylidene propyl sorbitol nucleating agent is included in the amount of 0.1-0.5 parts by weight based on the polypropylene polymer.
