Acrylonitrile butadiene styrene (ABS) is a common thermoplatstic used to make light, rigid, molded products. It is a copolymer made by polymerizing styrene and acrylonitrile polystyrene. The styrene gives the plastic a shiny, impervious surface. The butadiene, a rubbery substance, provides resilience even at low temperatures. ABS is considered superior for its hardness gloss, toughness, and electrical insulation properties.
