ABS: Acrylonitrile-butadiene-styrene is the most widely used engineering thermoplastic today.

ABS is part of the family of thermoplastics based on acrylonitrile, butadiene and styrene combined by a variety of methods involving polymerization, graft copolymerization, physical mixtures, and combinations thereof. The standard grades are rigid, hard and tough, and possess good impact strength, heat resistance, low temperature properties, chemical resistance, and electrical properties. ABS compounds in pellet form and can be extruded, blow molded, calendered, and injection molded. ABS powders are used as modifiers for other resins, for example PVC.

Typical applications for ABS resins are household appliances, automotive parts, business-machine and telephone components, pipe and pipe fittings, packaging and shoe heels.
