ABS (Acrylonitrile Butadiene Styrene) is a very popular material thanks to its low cost and good mechanical properties. ABS is known for its toughness and impact resistance, it has a higher glass transition temperature, which means the material can withstand much higher temperatures before it begins to deform. This makes ABS a great choice for outdoor or high temperature applications.


  • Good heat resistance
  • Hard for a thermoplastic and is reasonably tough (maintains impact resistance to low temperatures).
  • It is easily processed (may be electroplated) and easily bonded
  • ABS has a good gloss surface finish.


  • Poor solvent and fatigue resistance. 
  • Poor UV resistance unless protected.
  • Maximum continuous use temperature approx. 70 °C ( 160 °F ).
  • Poor bearing properties (high friction and wear). 
  • High smoke evolution.
