Acrylonitrile butadiene styrene (ABS)
2-4 usd/kg
Acrylonitrile butadiene styrene (ABS) is used in so many everyday applications that it has become very familiar. Its combination of impact strength with high quality surface means it finds application in things like protective helmets, toys (Lego), tableware, lighting, containers and consumer electronic devices (mobile phones, headphones, wearable electronics). Meanwhile, its balance of price and mechanical properties make it favourable in applications spanning automotive and furniture. It is a terpolymner that combines the rigidity and performance of acrylonitrile (A) and styrene (S) copolymer with the exceptional toughness of polybutadiene or a butadiene copolymer (B). The versatility of this combination means this plastic can be tailored to a range of requirements. In terms of cost and performance, ABS bridges the gap between high-performance engineering plastics, such as polycarbonate (PC), and commodity polypropylene (PP).

Acrylonitrile butadiene styrene (ABS) sheet is co-extruded, or coated – also known as ‘capped’ – with a range of materials to impart specific surface properties in the thermoformed part. For example, acrylic (PMMA) is added for improved weather resistance, colour, gloss and scratch resistance. It can be printed, too, such as with pictures and patterns that help to further conceal wear and tear. The finish can be glossy or matte, and these materials are found in a range of applications, from transport to bathrooms (frosted glazing, bathtubs and jacuzzis for example). Thermoplastic polyurethane (TPU), on the other hand, is added to create a soft, grippy and hardwearing surface, such as is useful for furniture applications.
