| 摘要 |
A flame retardant polytrimethylene terephthalate resin composition, comprising: 30 to 99 parts by weight of (A) a polytrimethylene terephthalate resin, and 1 to 70 parts by weight of at least one flame retardant selected from the group consisting of (B-1) phosphorus-containing flame retardant and (B-2) nitrogen-containing flame retardant, is disclosed. The composition has superior mechanical characteristics, chemical resistance, electrical characteristics, weatherability, heat aging resistance and hydrolysis resistance, and has superior moldability, good appearance with less warpage deformation when molded, and furthermore has superior flame retardance and does not generate highly corrosive hydrogen halide gas upon combustion.
