Le PA6 résiste bien aux huiles minérales, graisses, carburants et solvants aliphatiques. Sensible aux acides forts et bases concentrées. L'absorption d'eau modifie ses propriétés mécaniques (plastification). Incompatible avec les oxydants forts.

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.
PA6 is recyclable (code 7). Depolymerisation enables the recovery of caprolactam. Mechanical recycling is widely practiced in the automotive and textile industries.
PA6 grades are approved for food contact (FDA, EU regulation). Avoid contact with highly acidic or alcoholic foods. Check the specific grade.
