POLYPROPYLENE COMPOSITION WITH VERY HIGH RIGIDITY AND IMPACT STRENGTH

摘要

PURPOSE: A polypropylene resin composition is provided to improve rigidity and impact strength and to enable use for the parts for electronics, the parts for IT products, and the parts for vehicles. CONSTITUTION: A polypropylene resin composition comprises 25.0~60.0 weight% of a polypropylene resin, 30.0~50.0 weight% of glass fiber, 5.0~30.0 weight% of nylon, and 5.0~20.0 weight% of compatibilizer. The melt index of the polypropylene resin is 1~50 g/10 minute. The nylon resin is nylon 6, and nylon 66 or nylon 6 /66 as a mixture thereof. The compatibilizer is a maleic anhydride-grafted ethylene propylene copolymer, a maleic anhydride-grafted polypropylene copolymer, or a maleic anhydride-grafted alpha-olefin copolymer.
