UPE Wear-Resistant Composite Screw Flight

Product Overview

UPE (Ultra-High Molecular Weight Polyethylene) Composite Screw Flights represent a breakthrough in wear-resistant conveying technology. These specialized spiral blades combine the exceptional abrasion resistance of UPE polymer with structural steel backing, creating the ultimate solution for handling highly abrasive materials. Our composite design delivers 8-10 times longer service life than conventional carbon steel flights in severe wear applications.

Structural Composition

1. Wear Surface - 8-25mm thick UPE sheet (Molecular weight 5-9 million)

2. Structural Backing - Q345B carbon steel or SS304 stainless steel base

3. Bonding System - High-strength adhesive with mechanical interlock

4. Edge Protection - Reinforced wear-resistant alloy edge caps

5. Modular Design - Replaceable wear segments for easy maintenance
