ABS is formed by combining three monomers - Acrylonitrile, Butadiene, and Styrene. Each monomer contributes to the final ABS product. Acrylonitrile contributes heat resistance, high strength and chemical resistance. Butadiene provides impact strength, toughness, and low temperature property retention. Styrene, on the other hands gives gloss, rigidity and processabilitv.
Several types of rigid sheeting using ABS resins and compounds are manufactured. Each type is designed to meet specific end use requirements, depending on the properties desired.
All calendered or extruded sheets contain strains imparted by processing. These strains may be released by exposing the sheet to sufficient heat. Pressed sheets, however, are almost strain free - only pressed sheets should be used in structural fabrications.
ABS is vacuum formed or injection molded in most applications, except forays pipe, which is used in oil fields, chemical plants, natural gas carriage and home water systems. ABS is relatively easy to fabricate, weld, thermoform or bond.
