Acrylonitrile butadiene styrene (ABS) (chemical formula (C8H8)x·
(C4H6)y·(C3H3N)z) is a common thermoplastic. Its glass transition
temperature (ABS is amorphous and therefore has no true melting
point) is approximately **5 °C (**1 °F).
It is a terpolymer made by polymerizing styrene and acrylonitrile
in the presence of polybutadiene. The proportions can vary from *5
to *5% acrylonitrile, 5 to *0% butadiene and *0 to *0% styrene. The
result is a long chain of polybutadiene criss-crossed with shorter
chains of poly(styrene-co-acrylonitrile). The nitrile groups from
neighboring chains, being polar, attract each other and bind the
chains together, making ABS stronger than pure polystyrene. The
styrene gives the plastic a shiny, impervious surface. The
butadiene, a rubbery substance, provides resilience even at low
temperatures. For the majority of applications, ABS can be used
between **0 and *0 °C (*4 and **6 °F) as its mechanical properties
vary with temperature. The properties are created by rubber
toughening, where fine particles of elastomer are distributed
throughout the rigid matrix.
Production of 1 kg of ABS requires the equivalent of about 2 kg of
petroleum for raw materials and energy. It can also be
recycled.
ABS plastic is damaged by sunlight. This caused one of the most
widespread and expensive automobile recalls in US history.
ABS's light weight and ability to be injection molded and
extruded make it useful in manufacturing products such as
drain-waste-vent (DWV) pipe systems, musical instruments
(recorders, plastic clarinets, and piano movements), golf club
heads (due to its good shock absorbance), automotive trim
components, automotive bumper bars, medical devices for blood
access, enclosures for electrical and electronic assemblies,
protective headgear, whitewater canoes, buffer edging for furniture
and joinery panels, luggage and protective carrying cases, small
kitchen appliances, and toys, including Lego bricks.[8]
ABS plastic ground down to an average diameter of less than 1
micrometer is used as the colorant in some tattoo inks.[citation
needed] Tattoo inks that use ABS are extremely vivid. This
vividness is the most obvious indicator that the ink contains
ABS[citation needed], as tattoo inks rarely[9] list their
ingredients.
ABS is also commonly used in rapid prototyping extrusion-based 3D
printers. Its glass transition temperature makes it a material of
choice for rapid prototyping — relatively high as to reduce
unwanted deformation at slightly elevated temperatures but low
enough to be safely attainable with standard extrusion setups.
