UHMW-PE High Temperature
Overview
What is the Material: UHMW-PE High Temperature is a semi-crystalline material filled with a proprietary additive.
Key Material Features: This material is beneficial for maintaining its key properties at temperatures that exceed the normal range of UHMW-PE, while maintaining many properties of other UHMW-PE materials including wear resistance, impact resistance, corrosion resistance, chemical resistance, low friction, and low moisture absorption.
Other Considerations: This material is not typically recommended in applications involving drastic temperature changes and high loads.
