POLYMER COMPOSITION OF POLYESTER FOR METAL DEPOSITION

摘要

Provided is a thermoplastic polyester resin composition which is improved in metal deposition and is excellent in gloss after coating, moldability, durability, heat resistance and mechanical strength. The thermoplastic polyester resin composition comprises 100 parts by weight of a base resin comprising 40-80 parts by weight of a polybutylene terephthalate and 20-60 parts by weight of polyethylene terephthalate; 0.1-5.0 parts by weight of an epoxy-based resin stabilizer; 0.1-5.0 parts by weight of a pentaerythritol compound containing a long chain ester group; 0.1-10.0 parts by weight of an epoxy compound having at least two epoxy groups; 0-3 parts by weight of a silane compound having an organic functional group; and 2-35 parts by weight of glass fiber or an inorganic filler. Also the thermoplastic polyester resin composition comprises 100 parts by weight of a base resin comprising 40-80 parts by weight of a polybutylene terephthalate and 20-60 parts by weight of polyethylene terephthalate; 0.1-5.0 parts by weight of an epoxy-based resin stabilizer; 0.1-10.0 parts by weight of an epoxy compound having at least two epoxy groups; 0.1-3.0 parts by weight of a silane compound having an organic functional group; and 2-35 parts by weight of glass fiber or an inorganic filler.
