Acrylonitrile Butadiene Styrene (ABS)

ABS is a thermoplastic, further classified as a styrenic plastic. It has five common variants, each represented as a separate material. The material properties section shows ranges encompassing all variants. To see the details of each variant on a separate page, follow the links in the Variant Materials section further below.
