Acrylonitrile-Butadiene-Styrene
Introduction
Acrylonitrile-Butadiene-Styrene (ABS) entered mass production in the 1960s.
It is a thermoplastic.
Applications: ABS is common in electronic housings, auto parts, consumer products, pipe fittings, waste pipes, computer housings (electroplated on the inside), and automotive interior and exterior trim.
General properties: ABS is tough, hard, and rigid. It has good chemical resistance, dimensional stability, and creep resistance. It accepts electroplating and costs little. It has moderate mechanical strength, but it tends to stress crack. Acetone degrades (dissolves) ABS.
Trade Name: Cycolac, Lustran.
