High-Performance UHMWPE Wear Pads for Demanding Applications
Our UHMWPE wear pads are machined from 100% virgin ultra-high molecular weight polyethylene sheet, rod, or profile. They deliver exceptionally low friction, outstanding abrasion resistance, and reliable performance from -200°C to 80°C. We supply custom sizes up to 2000 mm × 1000 mm × 100 mm with tight tolerances and food-grade options.
Why Choose Our UHMWPE Wear Pads?
Low friction – Coefficient of friction 0.10–0.15 against steel, eliminates stick-slip and reduces drive power.
Superior wear resistance – Sand-slurry abrasion volume loss ≤80 mm³ (ASTM G65), outlasts nylon 6 by 2–3×.
Zero water absorption – <0.01% water absorption, no swelling in fresh or salt water.
Impact resistant – Remains ductile at -200°C, does not crack under hammer impact.
Food-safe options – FDA 21 CFR 177.1520 compliant natural and green grades available.
UV-stabilized grades – Black UV-resistant material retains >90% tensile strength after 5000 h QUV.

Frequently Asked Questions
Q: What is the difference between UHMWPE and HDPE?
UHMWPE has a much higher molecular weight (≥4.5 million g/mol) than HDPE, giving it significantly better abrasion resistance, impact strength, and lower friction.
Q: Can you machine UHMWPE to my exact drawing?
Yes, we provide full OEM/ODM services. Send us your drawing and we will quote within 24 hours. Tolerances down to ±0.05 mm are available.
Q: Is UHMWPE suitable for food contact?
Yes, natural and green grades comply with FDA 21 CFR 177.1520 for direct food contact.
Q: What is the maximum operating temperature?
Continuous service temperature is -200°C to 80°C, with short-term peaks up to 95°C.
Q: Do you offer UV-stabilized UHMWPE?
Yes, black UV-resistant grades are available with tensile strength retention >90% after 5000 h QUV testing.
