ABS is a terpolymer made by polymerizing styrene and acrylonitrile in the presence of polybutadiene. ABS combines the strength and for its hardness, gloss, toughness, and electrical insulation properties. Its shape and structure can be altered or damaged by sunlight. It is flammable when exposed to high temperatures. The most important mechanical properties of ABS are impact resistance and toughness.
A variety of modifications can be made to improve impact resistance, toughness, and heat resistance. The impact resistance can be amplified by increasing the proportions of polybutadiene in relation to styrene and also acrylonitrile, although this causes changes in other properties. Impact resistance does not fall off rapidly at lower temperatures. Stability under load is excellent with limited loads.
Thus, by changing the proportions of its components, ABS can be prepared in different grades. Two major categories could be ABS for extrusion and ABS for injection molding, then high and medium impact resistance. Generally ABS would have useful characteristics within a temperature range from −20 to 80 °C (−4 to 176 °F).
ABS’s light weight and ability to be melted and extruded make it useful in manufacturing goods. Household and consumer goods comprise the major applications of ABS. it can be used to make things like drain-waste-vent (DWV) pipe systems, musical instruments (recorders, plastic clarinets, piano movements), golf club heads (because of its good shock absorbance), automotive trim components, automotive bumper bars, medical devices for blood access, enclosures for electrical and electronic assemblies, keyboard keycaps, protective headgear, whitewater canoes, buffer edging for furniture and joinery panels, luggage and protective carrying cases, small kitchen appliances, and toys.
