A thermoplastic resin composition of the present invention comprises: approximately 100 parts by weight of a polycarbonate resin; approximately 20-80 parts by weight of a polyphenylene ether resin; approximately 15-70 parts by weight of glass fiber; approximately 1-10 parts by weight of epoxy-modified polystyrene; approximately 1-20 parts by weight of a styrene-ethylene/butylene-styrene copolymer; and approximately 0.2-4 parts by weight of dihydro-9-oxa-10-phosphaphenanthrene-10-oxide (DOPO), wherein the weight ratio of the epoxy-modified polystyrene and the styrene-ethylene/butylene-styrene copolymer is approximately 1:0.5 to 1:10. The thermoplastic resin composition has excellent impact resistance, flowability, appearance characteristics and the like, and has low dielectric constant, dielectric loss and the like.
The present invention relates to a thermoplastic resin composition comprising, relative to 100 parts by weight of a base resin containing (A) 50 to 70 wt% of a polycarbonate resin, (B) 10 to 30 wt% of a polysiloxane-polycarbonate copolymer resin, and (C) 10 to 20 wt% of a polybutylene terephthalate resin, (D) 1 to 3 parts by weight of siloxane modified polyester, (E) 1 to 3 parts by weight of syndiotactic polystyrene, and (F) 0.5 to 2 parts by weight of a benzotriazole-based ultraviolet stabilizer.
