Claims20
A composition (C) comprising:
- from 20 to 85 wt. % based on the total weight of the composition, of at least one polyamide polymer (PA) having a glass transition temperature (Tg), measured by DSC, of at least 130° C.;
- from 10 to 75 wt. % based on the total weight of the composition, of at least one fibrous filler (F);
- and
- from 0.01 to less than 5 wt. % based on the total weight of the composition, of at least one additive (A) selected from the group consisting of:
- oxides of alkaline earth metals;
- carbonates of alkaline earth metals;
- phosphates of alkaline earth metals;
- sulphates of alkaline earth metals;
- sulphates of alkaline metals;
