Abstract
An eco-friendly fire-retardant polymer composition, a molded article made from the composition, and a method of manufacturing the molded article. The composition includes: a thermoplastic resin containing polycarbonate; a bio-based resin containing polytrimethylene terephthalate extracted from a biomaterial; and an impact modifier containing a core-shell type elastomer.
Claims25
A polymer composition comprising:
- 40 to 60 wt % with respect to the weight of the polymer composition, of polycarbonate resin having a Melt Index exceeding 10 g/10 min at 300° C. and 1.2 kg;
- 20 to 30 wt % with respect to the weight of the polymer composition, of polycarbonate having a Melt Index of 10 q/10 min or less at 300° C. and 1.2 kg;
- 5 to 20 wt % of a polysiloxane-polycarbonate resin with respect to the weight of the polymer composition;
- 3 to 15 parts of weight (wt %) of a bio-based resin with respect to the weight of the polymer composition, the bio-based resin containing polytrimethylene terephthalate produced from a biomaterial;
- and
- an impact modifier containing a core-shell type elastomer.
