TWINS AMONG THE POLYAMIDES

The mechanical porperties of PA 6 und PA 66 with different glass fibre contents have been determined in extensive statistical tests. In the freshly injected state, both products are very similar in their mechanical properties. Their behaviour is mainly determined by the glass fibre content. In the conditioned state, the mechanical values of PA 66 types (with the exception of toughness) lie perhaps at a higher level on account of lower water absorption. Regarding processing and thermal aging, however, the PA 6 types perform better.
