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.

ABS Injection Molding Applications

The material properties of ABS make it a good choice when impact resistance, strength, and stiffness are required. A few key applications include:

  • Cosmetic parts
  • Enclosures
  • Handheld devices
  • Housings for electrical tools, remote controls, computers, and telephone components

ABS is also widely used in prototyping because it is relatively inexpensive and has excellent dimensional stability for product testing.
