POLYPROPYLENE COMPOSITION WITH EXCELLENT IMPACT RESISTANCE AND SCRATCH RESISTANCE

摘要

The present invention provides a polypropylene resin composition which comprises: (A) 10 to 70 wt% of a crystalline ethylene-propylene copolymer; (B) 5 to 30 wt% of an ethylene-α-olefin copolymer; (C) 5 to 30 wt% of polypropylene elastomer; (D) 5 to 40 wt% of an inorganic filler including talc and precipitated calcium carbonate, and selectively including heavy calcium carbonate; and (E) 1 to 10 wt% of modified polypropylene. According to the present invention, the composition can widely apply price competitiveness of an original price to a car built-in component, a household electrical appliance, etc. as having an excellent property such as high strength, impact resistance, scratch resistance, etc., being rarely transformed, and being capable of replacing an expensive whisker.
