Semi-Crystalline Engineering Plastics
Engineering thermoplastics with moderate strength and stiffness and are used for bearing and wear applications or structural parts
General Characteristics of Semi-Crystalline Engineering Plastics
- General purpose structural parts
- Moderate strength
- Moderate temperature
- Good dimensional stability
- Good izod impact
- Easily fabricated
Semi-crystalline engineering plastics can be considered for applications with an approximate maximum temperature of 250°F. Selecting a plastic material for use in a high temperature environment requires careful review of material properties data.
