Composition and Properties of ABS

Acrylonitrile Butadiene Styrene (ABS) is a versatile thermoplastic material composed of three main monomers: acrylonitrile, butadiene, and styrene.

The composition of ABS can vary, with typical ranges being 15% to 35% acrylonitrile, 5% to 30% butadiene, and 40% to 60% styrene. Each monomer contributes to the unique properties of ABS, making it a desirable material for various applications.

  • The acrylonitrile component provides ABS with strength, chemical resistance, fatigue resistance, hardness, and rigidity.
  • The butadiene component enhances ABS’s toughness and ductility, especially at low temperatures.
  • The styrene component imparts a shiny, impervious surface, as well as hardness, rigidity, and improved processing ease.

Additionally, ABS contains fine particles of polybutadiene elastomer distributed throughout the rigid matrix, which contribute to its toughness and ductility, particularly at low temperatures.

ABS is amorphous and does not have a true melting point. However, it has a glass transition temperature of approximately 105°C. This temperature range allows ABS to be used effectively between -20°C and 80°C.
