ABS resists dilute acids, bases, and mineral oils. Sensitive to aromatic solvents (toluene, acetone), chlorinated hydrocarbons, and esters. Prolonged contact with greases can cause stress cracking. Not recommended in strong oxidizing environments.

Les grades GF requièrent des pressions d'injection plus élevées. Retrait fortement anisotrope (perpendiculaire aux fibres > dans l'axe). Usure des buses et moules accrue — aciers nitrurés recommandés. Séchage identique au grade de base.
ABS is recyclable (code 7). It can be remelted and re-injected several times with slight degradation of its properties. Industrial recycling channels exist for production waste. End-of-life recycling remains limited by selective collection.
Standard ABS is not certified for food contact. Special ABS-FDA grades exist but remain marginal. Prefer PP, PE, or PETG for common food applications.
