Abstract
Disclosed is a thermoplastic resin composition. Due to addition of the epoxy-based resin, the phosphorous-based flame retardant, the silicon-based compound and the calcium carbonate to the basic resin according to the present invention, a thermoplastic resin composition having superior flame retardancy and excellent rigidity, heat resistance and processability, and a molded article manufactured therefrom may be provided.
Claims14
A thermoplastic resin composition comprising:
- 100 parts by weight of a basic resin comprising 10 to 90% by weight of an acrylonitrile-butadiene-styrene (ABS) copolymer and 90 to 10% by weight of a vinyl aromatic compound-vinyl cyano compound copolymer selected from styrene-acrylonitrile (SAN), polystyrene (PS), and high impact polystyrene (HIPS);
- 1 to 30 parts by weight of an epoxy-based resin;
- 1 to 30 parts by weight of a phosphorous-based flame retardant;
- 1 to 10 parts by weight of a silicon-based compound;
- and
- 1 to 5 parts by weight of a calcium carbonate compound,
- wherein a viscosity of the silicon-based compound is 300,000 to 800,000 cst, and
- wherein the thermoplastic resin has a UL 94 flammability rating of V-1.
