Title:
POLYPROPYLENE RESIN COMPOSITION FOR MATERIAL FOR PHYSICAL DISTRIBUTION
Document Type and Number:
Japanese Patent JP3109049
Kind Code:
B2
Abstract:
PURPOSE: To obtain a polypropylene resin composition for materials for physical distribution, such as pallets and containers, having excellent impact resistance especially at a temperature as low as about -30°C and high rigidity as a well.
CONSTITUTION: This resin composition comprises 58-78 pts.wt. propylene/ethylene block copolymer having an MFR of 5-50g/10min, an ethylene content of 4-10mol% and a stereo-regularity of the propylene component of 97% or above, 18-28wt.% propylene/ehylene random copolymer having an MFR of 0.1-2g/10min, an ethylene content of 75mol% or above and a degree of crystallinity of 10% or below as measured by X-ray diffractometry and 4-15wt.% talc having a mean particle diameter of 0.5-5μm, and has an MFR of 1.5-25g/10min and ethylene content of 18-34mol% and a density of 0.94-1.02g/cm3, an initial bending modulus of 12000 or above at 23°C and an Izod impact strength of 8kg.cm/cm or above at 0°C.
