Acrylonitrile Butadiene Styrene (ABS)

ABS is a thermoplastic, further classified as a styrenic plastic. The properties of ABS include five common variations. The property values on this page show ranges across all of them. For more specific values, follow the links immediately below. The graph bars on the material properties cards further below compare ABS to: styrenic plastics (top), all thermoplastics (middle), and the entire database (bottom).
