Title:
POLYPROPYLENE-BASED RESIN COMPOSITION
Document Type and Number:
Japanese Patent JP2008019347
Kind Code:
A
Abstract:
To provide a polypropylene-based resin composition capable of giving automotive injection-molded form with excellent low-temperature impact resistance and low gloss.
The polypropylene-based resin composition comprises 58-80 wt.% of (A) a polypropylene resin meeting specific requirements, 1-16 wt.% of (B) an ethylene--olefin copolymer rubber 0.02-0.5 g/10min in melt flow rate, 1-16 wt.% of (C) an ethylene--olefin copolymer rubber 1-20 g/10min in melt flow rate, and 18-25 wt.% of (D) an inorganic filler, wherein a total of the copolymer rubbers(B) and (C) accounts for 2 wt.% or greater but less than 17 wt.% of the whole composition.
