PEI 30% Glass


What is the Material: PEI 30% Glass is an amorphous material filled with glass fibers.

Key Material Features: This material is beneficial in applications requiring improved rigidity, mechanical strength, and dimensional stability, while maintaining properties of other PEI materials including hydrolysis/steam resistance and temperatures resistance.

Other Considerations: The glass fibers increase the materials structural properties, but the glass fibers can be abrasive. This material is typically not recommended in bearing and wear applications.
