Comparing ABS Material Properties

Acrylonitrile butadiene styrene (ABS) stands out as a robust and impact-resistant plastic. Its attributes include low shrinkage, excellent dimensional stability, and resistance to corrosive chemicals, rendering it highly adaptable across diverse industries. ABS boasts a glass transition temperature of around 221°F (105°C) and is classified as an amorphous polymer, granting it elevated temperature endurance without a distinct melting point.
