PA6.6 – Polyamide 6.6 PA6.6 GF50
AKROMID® A3 GF 50 ECO black (8571)AKROMID® A3 GF 50 ECO black (8571) is a 50% glass fibre-reinforced, heat-stabilised polyamide 6.6. The material is suitable for technical components in mechanical engineering and the automotive industry with demands for high stiffness and strength. The formulations of the sustainable ECO products are partly based on regenerated post-industrial feedstock (at least 30 weight-% by recipe) and thus contribute to reducing the consumption of valuable raw materials. The product can be laser marked.
