ABS (ACRYLONITRILE / BUTADIENE / STYRENE)

ABS (ACRYLONITRILE / BUTADIENE / STYRENE)

Material Information

ABS is formed by combining three monomers – Acrylonitrile, Butadiene, and Styrene. This medium priced thermoplastic offers a combination of impact and abrasion resistance, tensile strength, dimensional stability, heat resistance, rigidity, low temperature properties, chemical resistance and good electrical characteristics. ABS is ideal for turning, drilling, sawing, milling, die-cutting, cold stamping, and shearing. This material is easy to glue and paint with non petroleum-based products. Petroleum based products should not be used because they will cause the material to craze. ABS is also one of the few non-metallic materials that can be readily electroplated. ABS is produced in thin gauge sheet with Haircell/Smooth finish and a Smooth/Smooth finish. ABS is also produced in an Industrial grade in thicker plate and rod.
