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.

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.
Injection at 200–260 °C, mould at 40–80 °C. Reproducible shrinkage rate (0.4–0.7 %). Recommended pre-drying: 2–4 hours at 80 °C. Avoid thermal degradation above 280 °C. Good flow, suitable for thin-walled parts.
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.
