High molecular weight polyethylene scraper combines excellent properties such as high wear resistance, high impact resistance, non-stick surface, and self-lubricating properties. Moreover, it maintains its mechanical properties even under low-temperature conditions. High molecular wear-resistant lining is a polymer with high viscosity in powder form, with a typical particle size range of 100-200 micrometers. Due to its high viscosity, it cannot be processed using standard thermoplastic molding methods but is instead processed by molding or plunger extrusion techniques, melting and sintering ultra-high molecular weight polyethylene particles under high pressure into blanks or profiles, followed by further machining if necessary. Due to its wear resistance, chemical resistance, and good friction properties, the main application fields include bulk material handling, food and beverage processing machinery, chemical industry, mining and mineral processing equipment, recreational facilities, transportation, and orthopedic implants.
High molecular weight polyethylene boasts numerous properties; let me explain them to you next.
High molecular weight polyethylene boards retain the superior properties of ultra-high molecular weight polyethylene boards, such as high impact strength, low friction coefficient, and excellent self-lubricating performance, while also catering to various performance requirements of customers. For instance, flame-retardant high molecular weight polyethylene boards are difficult to ignite, can extinguish automatically within 3-10 seconds after being removed from the flame source, and do not drip, produce little smoke, emit harmless volatiles, and have been certified as green and environmentally friendly materials by the National Flame Retardant Material Research Institute, demonstrating high promotion and application value. Additionally, there are also boards with wear resistance, high-temperature resistance, and high strength, among others.

Properties of Ultra-High Molecular Weight Polyethylene:
High molecular weight polyethylene plates are highly wear and tear-resistant, with the material's wear resistance and impact resistance increasing as the molecular weight increases; they are used in a wide range of mechanical tracks.
2. High molecular weight polyethylene plates have high impact strength among existing plastics, maintaining considerable impact resistance even at 70°C.
3. Self-lubricating
4. Low water absorption. Therefore, its physical and mechanical properties are unrelated to the humidity factors in the working conditions it is used in.
5. High-molecular-weight polyethylene plates exhibit chemical stability and can withstand the corrosion from various corrosive media such as acids, alkalis, salts, and organic solvents within certain temperature and concentration ranges.
6. High molecular weight polyethylene boards are odorless, non-toxic, and odorless, inherently non-corrosive, with physiological circulation and adaptability.
Non-stick properties.
8. When the molecular weight of high-density polyethylene exceeds 500,000, its脆ization temperature drops to 140°C. Ultra-high molecular weight polyethylene can even maintain some mechanical strength at temperatures below 269°C under the action of liquid nitrogen.
