POLYPROPYLENE RESIN COMPOSITION WITH IMPROVED SCRATCH-RESISTANCE, COMPRISING POLYPROPYLENE RESIN, INORGANIC FILLER, ADDITIVE AND HIGH MOLECULAR WEIGHT SILICONE RESIN

摘要

PURPOSE: Provided is polypropylene resin composition having improved scratch-resistance, which shows improved productivity and cost saving effects. CONSTITUTION: The polypropylene resin composition with improved scratch-resistance, comprises (A) 53.0-93.4 wt% of polypropylene resin, (B) 5.0-40.0 wt% of an inorganic filler, (C) 0.1-2.0 wt% of an additive and (D) 1.5-5.0 wt% of high molecular weight silicone resin. In the composition, the polypropylene resin is a homopolymer of propylene or a terpolymer of ethylene-propylene, the inorganic filler is at least one selected from talc, kaolin and calcium carbonate, the additive is at least one selected from an anti-oxidant, a neutralizing agent, a weather-resistant stabilizer and a nucleating agent, and the high molecular weight silicone resin has a number average molecular weight of 500,000-1,000,000.
