GF grades require higher injection pressures. Strongly anisotropic shrinkage (perpendicular to fibres > along axis). Increased nozzle and mould wear — nitrided steels recommended. Drying identical to base grade.
PA66 is recyclable. Depolymerisation into hexamethylenediamine and adipic acid is industrially feasible. Mechanical recycling is used for automotive production waste.
PA66 can be approved for food contact for specific grades, but applications remain limited. Prefer PA6-FDA for common food applications.
Choose the right material for your application by comparing PA66+GF to alternatives on thermal, mechanical, chemical and cost criteria.
