POLYPROPYLENE RESIN COMPOSITION HAVING THE IMPROVED RESISTANCE TO BLOOMING

摘要

A polypropylene resin composition is provided to ensure good blooming resistance while exhibiting flame retardancy of the flammability class UL-94 V-2 even in a thickness of 1/32 inch. A polypropylene resin composition comprises (A) 75.0-95.0wt% of polypropylene resin, (B) 1.0-20.0wt% of a bromine-based flame retardant having good blooming resistance, (C) 1.0-5.0wt% of a flame retardant aid, and (D) 0.01-10.0wt% of a synthetic adsorbent. The polypropylene resin(A) has a melt index of 1-50 g/10minutes(230 °C) and is a propylene homopolymer and ethylene-propylene copolymer having crystallinity. The flame retardant aid(C) is antimony trioxide.
