Frequently asked questions
Injection at 270–310 °C, mould at 80–100 °C. Pre-drying required: 6 hours at 85 °C. High processing temperature → higher energy consumption than PA6. Anisotropic shrinkage (0.8–2.0 %), compensated for by reinforcements.
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.
