L'ASA offre une bonne résistance aux huiles, graisses et détergents courants. Résistance aux solvants organiques (acétone, toluène) similaire à l'ABS : limitée. Tenue aux UV nettement supérieure grâce aux groupements acrylate.

Frequently asked questions
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.
ASA is recyclable (code 7). Its UV-stabilised properties are maintained better after recycling than ABS. Primarily industrial avenues.
Standard ASA is not certified for food contact. Use PP or PE for all food applications.
