What is Acrylonitrile butadiene styrene?

Acrylonitrile butadiene styrene (CAS 9003-56-9), commonly known as ABS plastic, is a thermoplastic terpolymer used across manufacturing industries for its balance of rigidity, toughness, and processability.

Where is Acrylonitrile butadiene styrene used?

  • Automotive: interior trim panels and dashboards
  • Electronics: device enclosures, keyboard components, and connectors where precise molding tolerances are critical
  • Building and construction: pipe fittings, drainage systems, and protective housings
  • Consumer goods: appliance casings and power tool bodies
  • It is a primary material choice where impact resistance and dimensional stability are required in finished parts.

Commercial specifications

  • Grades are differentiated by impact resistance, heat deflection temperature, and flame retardancy.
  • General-purpose, high-impact, and flame-retardant classifications.
  • Specialty grades include plating-grade ABS for electroplating and transparent ABS for aesthetic end uses.
