POLYPROPYLENE RESIN COMPOSITION

摘要

A polypropylene resin composition is provided to realize an excellent deodorizing effect while maintaining good physical properties including tensile strength and heat resistance, and to obtain a material useful for producing car interior materials, food containers and packaging materials. A polypropylene resin composition comprises: (a) 40-80 wt% of a crystalline polypropylene resin; (b) 5-30 wt% of ethylene-alpha-olefin copolymer; (c) 5-30 wt% of an inorganic filler having a particle size of 0.5-10 micrometers; and (d) 3-30 wt% of phyllite having a particle size of 5-20 micrometers and a specific gravity of 2.6-2.7. The crystalline polypropylene resin has a melt flow index of 0.5-150 g/10 min (230 deg.C, 2.16 kg), and contains 0.5-15 wt% of ethylene-propylene rubber.
