Compare Material Properties of ABS Materials
Acrylonitrile butadiene styrene (ABS) is a tough, impact-resistant plastic. Its low shrink, high dimensional stability, and good resistance to corrosive chemicals make it a versatile option used across a variety of industries. ABS has a glass transition temperature of approximately 221 °F (105 °C) and is an amorphous polymer, meaning it has high temperature resistance and no true melting point.
