Thermoplastic Styrene Resin Composition with good Heat Stability, Light Stability, and Impact Strength

摘要

The present invention is 30-99 parts by weight of a styrene-based resin and polyester resin base consisting of 1-70 parts by weight 100 parts by weight of the resin, 0.1 to 10 parts by weight of a copolyester resin, a primary phenolic antioxidant compound is 0.05 to 2 parts by weight, the secondary phosphite compound is from 0.05 to 4 parts by weight of an antioxidant, to seugye compound, benzotriazole (Benzotriazole) compound and heat from the group consisting of a mixture comprising a compound selected from 0.2 to 6.0 parts by weight stable, the present invention relates to an excellent light stability and the impact resistance of styrene-based thermoplastic resin composition.
