It is a high-performance polyamide 46 reinforced engineering polymer with 40% glass fiber. It retains its mechanical properties at high temperatures up to 220°C, this makes it ideal for extremely high-performance applications, where it outperforms PPA, PA6T, PA9T, and often PPS and LCP. Depending on the grade there are heat stabilized and different flow properties are available.
