Abstract

The present invention relates to a high-strength inflammable blend resin composition including a polyphenylene sulfide resin and a polyethylene terephthalate resin. More specifically, the resin composition of the present invention includes: a basic blend resin containing 10 to 80 wt. % of a polyphenylene sulfide resin, and 20 to 90 wt. % of a polyethylene terephthalate resin; and 0.1 to 20 parts by weight of a modified polystyrene or a styrene-based elastomer with respect to 100 parts by weight of the basic blend resin.
