UHMWPE Wear Pads are machined from ultra-high molecular weight polyethylene sheet, rod, or profile. Also supplied as UHMWPE wear strips, UHMW wear pads, or virgin UHMW polyethylene wear components. We machine parts up to 2000 mm × 1000 mm × 100 mm. Standard tolerance is ±0.10 mm. Tighter tolerances down to ±0.05 mm can be quoted. Standard surface finish is Ra 1.6 µm. Natural (white), black, and green (FDA) colours are available. Continuous operating temperature is -200 °C to 80 °C.
Applications
- Chute and hopper liners
- Conveyor guide rails and wear strips
- Marine dock fender pads and rubbing strips
- Agricultural machinery slide plates
- Food processing machinery scrapers and guides
- Automotive and truck trailer rub blocks

Key Performance Data
- Static friction coefficient 0.10–0.15 against polished steel. UHMWPE wear pads eliminate stick-slip at low speeds.
- Abrasion resistance (sand-slurry test per ASTM G65): volume loss ≤80 mm³. Outlasts nylon 6 by 2–3× in sliding wear against abrasive materials.
- Water absorption <0.01%. No swelling in fresh or salt water. Dimensional change in 100% humidity is less than 0.1%.
- Notch-free impact strength. Remains ductile at -200 °C. Does not crack under hammer impact.
- FDA 21 CFR 177.1520 compliant grades available for food contact.
- UV-stabilized black grades available. Tensile strength retention after 5000 h QUV: >90%.
Certifications & Compliance
- ISO 9001:2015 — certified quality management system.
- RoHS (Directive 2011/65/EU) — compliant.
- FDA 21 CFR 177.1520 — compliant natural and green grades for food contact.
- Third-party test reports for tensile, abrasion, and friction coefficient available upon request.
