ABS

‍‍‍ABS (Acrylonitrile Butadiene Styrene) – Product Specifications

ABS is a tough, rigid, and impact-resistant engineering thermoplastic with good mechanical strength, excellent surface finish, and high dimensional stability. It is a terpolymer that combines the rigidity of styrene, the chemical resistance of acrylonitrile, and the toughness of butadiene rubber. ABS is widely used in automotive, electronics, consumer goods, and industrial applications where a balance of strength, aesthetics, and processability is required.
