1. Improved Wear Resistance
    One notable property of high molecular weight polyethylene is its extremely high wear resistance, which is highly valuable in many engineering applications. It has better wear resistance than all other plastics, and even surpasses the wear resistance of many metallic materials (such as carbon steel, stainless steel, bronze, etc.). The higher the molecular weight of polyethylene, the more wear-resistant the material becomes.
2. Extremely High Impact Resistance
    The impact strength of ultra-high molecular weight polyethylene is related to its molecular weight. When the molecular weight is below 2 million, the impact strength increases with molecular weight growth, peaking around 2 million. Beyond this peak, further increases in molecular weight lead to a decrease in impact strength. This is due to the molecular chains significantly hindering its crystalline structure, resulting in large amorphous regions within the macromolecules that can absorb a greater amount of impact energy. According to literature, the impact strength values of ultra-high molecular weight polyethylene and other plastics measured by ASTM-D256 show that the room temperature impact resistance of ultra-high molecular weight polyethylene is comparable to that of polycarbonate, known for its impact resistance, and is applicable to commonly used engineering plastics. Even at -40°C, ultra-high molecular weight polyethylene still has excellent impact resistance, and retains good impact resistance even at cryogenic temperatures of -269°C. This outstanding low-temperature characteristic extends the applications of ultra-high molecular weight polyethylene into low-temperature engineering fields.
