UHMWPE Wear-Resistant Liner
The UHMWPE wear-resistant liner redefines industrial wear protection through its lightweight, durable, chemically stable, and cost-effective performance. Whether resolving coal silo blockages, resisting abrasive ore flow, or ensuring food-grade safety, it delivers long-term reliability and operational efficiency. Choosing UHMWPE isn’t just a material decision—it’s an investment in sustainable, high-performance productivity.
Manufactured from ultra-high-molecular-weight polyethylene (UHMW-PE, molecular weight: 3–6 million), this engineered plastic sheet excels in wear resistance, impact toughness, self-lubrication, and chemical inertness. It outperforms traditional materials—including nylon, PTFE, stainless steel, and high-manganese steel—and is widely deployed across mining, power generation, construction, logistics, food processing, and chemical industries to solve challenges in material handling, storage, and equipment wear.
1. Core Advantages
Superior Wear Resistance & Extended Service Life
5–7× more wear-resistant than carbon steel and 4–5× better than stainless steel; slurry abrasion resistance of 70–120%.
Ideal for high-abrasion environments (e.g., coal, ore, cement), significantly reducing equipment replacement frequency and maintenance costs.
High Impact Resistance & Low-Temperature Adaptability
Maintains exceptional toughness from −40°C to +80°C, with notch impact strength of 80–170 kJ/m² (ASTM D256).
Absorbs impact energy, dampens vibration and noise—ideal for harsh climates or high-impact mining operations.
Self-Lubricating & Non-Stick Surface
Ultra-low coefficient of friction (0.07–0.11, comparable to ice), reducing flow resistance by up to 80% and eliminating bridging, adhesion, or blockages.
Ensures uninterrupted material flow in coal bunkers, grain silos, and chemical pipelines—no lubricants required.
Lightweight & Corrosion-Resistant
Density: 0.93–0.95 g/cm³ (≈1/8 that of steel)—simplifies installation and reduces structural load.
Resists acids, alkalis, seawater, and solvents; complies with FDA standards for direct food contact.
Maintenance-Free & Long-Term Stability
Water absorption <0.01%—unaffected by humidity; features anti-aging, flame-retardant, and anti-static properties.
Delivers a service life 3× longer than conventional materials.

Bolting: Recommended for high-impact zones (e.g., ore chutes).
Thermal Welding: For seamless, sealed joints using compatible UHMW-PE welding rods.
Embedded Mounting: Ideal for conveyors or chutes requiring flush, smooth surfaces.
Maintenance:
No lubrication or special upkeep required; periodic bolt inspection suffices.
Surface scratches do not compromise performance; damaged sections can be locally replaced.
