THERMOPLASTIC FLAME RETARDANT RESIN COMPOSITION

摘要

A thermoplastic flame resistant composition is provided to realize excellent impact strength and heat resistance while maintaining excellent flame resistance by using a phosphite compound. A thermoplastic flame resistant composition comprises: 100 parts by weight of a base resin containing 10-80 wt% of a rubber-modified styrene-containing graft copolymer and 20-90 wt% of a styrene-containing copolymer; and 1-10 parts by weight of a phosphite compound. The rubber-modified styrene-containing graft copolymer is obtained by graft copolymerization of 10-60 wt% of a rubbery ingredient with 30-65 wt% of a styrenic compound and 10-30 wt% of an acrylic compound.
