Material Specifications - Acrylonitrile Butadiene Styrene (ABS)

Material Specifications
Acrylonitrile Butadiene Styrene (ABS),
Impact Grade, Moulded


The most important mechanical properties of ABS are impact resistance and toughness. ABS is easily machined. Common machining techniques include turning, drilling, milling, sawing, die-cutting and shearing. ABS can be cut with standard shop tools and line bent with standard heat strips. ABS can be chemically affixed to itself and other like-plastics.


ABS's light weight and ability to be injection molded and extruded make it useful in manufacturing products, such as trim components, automotive bumper bars, enclosures for electrical and electronic assemblies. When melted into a filament, ABS plastic is a common material used in 3D printers, allowing APAC to conduct rapid prototyping.
