POLYPROPYLENE COMPOSITE RESIN COMPOSITION

摘要

PURPOSE: Provided is a polypropylene composite resin composition for use in automobile components and electric or electronic components, which has balanced physical properties and anti-scratch property. CONSTITUTION: The polypropylene composite resin composition comprises 50-98 wt% of an ethylene-propylene copolymer containing 10-20 wt% of the copolymerized ethylene monomer, 1-50 wt% of calcium silicate that is surface treated by an aminosilane and 0.05-0.5 wt% of a sorbitol-based crystallization inducer. The composition optionally further comprises an inorganic filler, or a compound selected from a group consisting of a styrene-butadiene rubber, an ethylene-propylene rubber, an ethylene-propylene-diene rubber, an ethylene-alpha-olefin rubber and a silicone resin.
