Filled compositions of thermoplastic polyamide and polyester |
摘要 |
An extruded profiled section characterized in that it has been extruded from a composition comprising a blend of a linear polyamide, a linear polyester containing at least 80% by weight of ethylene terephthalate units and an inorganic fibrous filler wherein the composition contains 5 to 60% by weight of the composition of the filler and the weight ratio of polyamide to polyester is between 1:1 and 49:1, which composition preferably has a melt flow index of not greater than 2 measured according to ASTM-D1238 using a standard die of bore 2.096 mm, length 8 mm and a load of 2.16 kg at a temperature of 285 DEG C. A preferred composition for preparing the extruded profiled section comprises a blend in which the polyamide contains an excess of terminal amino groups, and preferably at least 20 g equivalents of terminal amino groups per 106 g of polyamide, in excess of the carboxyl groups.
