Abstract:
The present invention relates to transparent polyamide-based composition, comprising: from 5.0 to 40.0% by weight of semi-crystalline polyamide, from 20.0 to 80.0% by weight of at least one amorphous, transparent and at least partially cycloaliphatic polyamide, from 0.0 to 5.0% by weight of PEBA, from 0.0 to 5.0% by weight of additives, and from 5.0 to 50.0%, preferably from 10.0 to 40.0% by weight, preferably from 20.0 to 30.0% by weight by weight of glass filler, where the glass filler, expressed as % by weight with respect to the total weight of filler, less than 60 wt. % silica (SiO2) and more than 5 wt. % of boron oxide (B2O3). The invention also relates to the manufacture of said composition, its use for the manufacture of transparent articles, said transparent articles and their process of manufacture.
