Acrylonitrile-butadiene-styrene (ABS) is the largest-volume engineering resin. Its biggest use is in the automotive industry, followed by the electronics sector. Other applications include domestic appliances, pipes, fittings and other construction products, and recreational items such as boats and mobile homes.
ABS is also blended with other polymers such as polycarbonate or polyvinyl chloride (PVC) for injection moulding applications.
An amorphous thermoplastic blend, ABS is available in a range of compositions and properties, depending on the ratio of monomer feedstocks (15-35% acrylonitrile, 5-30% butadiene and 40-60% styrene), to give a large number of grades and applications.
Due to its flexibility of composition and structure, ABS can exhibit a wide range of properties, allowing its use in diverse applications. ABS resins are composed of over 50% styrene and varying amounts of butadiene and acrylonitrile (ACN). Styrene provides rigidity and ease of processing, ACN offers chemical resistance and heat stability, and butadiene gives toughness and impact strength.
