POLYMER COMPOSITIONS, METHOD OF MANUFACTURE, AND ARTICLES FORMED THEREFROM

摘要

Disclosed herein is a thermoplastic composition comprising, based on the total weight of the composition: (a) from 10 to 80 wt. % of a polybutylene terephthalate; (b) from 10 to 80 wt. % of a copolyestercarbonate component, comprising a first copolyestercarbonate having a number average molecular weight of 15,000 to less than 28,000 Daltons, and a second copolyestercarbonate having a number average molecular weight of more than 28,000 to 40,000 Daltons, wherein a weight ratio of the first polyestercarbonate to the second polyestercarbonate is 95:5 to 20:80; (c) from 3 to 30 wt. % of a particulate filler; (d) from 0.1 to 10 wt. % of a fluoropolymer; and (e) from 3 to 25 wt. % of a polymeric impact modifier. A method of making the composition and an article comprising the thermoplastic composition are also disclosed.
