POLYPROPYLENE RESIN COMPOSITION FOR MEDICAL GRADE RESIN

摘要

A polypropylene resin composition for medical treatment is provided, which has improved transparency and mechanical properties like a flexural strength and a tensile strength and is harmless to human bodies. The polypropylene resin composition comprises; 97-99.97wt% of an ethylene random polypropylene having a melt index of 8-10, an ethylene content of 0.5-7.0mol%, and a xylene soluble index of less than 5.0%; 0.01-1.0wt% of a first antioxidant represented by the formula 1; 0.01-0.8wt% of a second antioxidant represented by the formula 2; 0.01-0.5wt% of an halide absorbent represented by the formula 3. In the formulas, R1 and R2 are independently C1-C5 alkyl groups and R3 and R4 are independently C1-C5 alkyl groups.
