Ultra-high molecular weight polyethylene special-shaped parts

Ultra-high molecular weight polyethylene products are a type of thermoplastic plastic with extremely long molecular chains, belonging to very rigid materials with high impact strength and excellent wear resistance. Ultra-high molecular weight polyethylene is a high-performance wear-resistant material with outstanding sliding properties, maintaining toughness even in low-temperature environments.

Excellent properties: Zero water absorption, does not adsorb oil or moisture, chemical corrosion resistance, high thermal conductivity, low dielectric constant, self-lubrication, UV radiation resistance. 1. Ultra-high molecular weight polyethylene sheets have the highest wear resistance among plastics, and the larger the molecular weight, the higher the material's wear resistance and impact resistance;
2. The impact strength of ultra-high molecular weight polyethylene sheets is the highest among existing plastics, and even at -70°C, it still retains considerable impact strength;
3. Self-lubricating, low friction coefficient, energy-saving, and feels like wax.

4. Extremely low water absorption. Therefore, its physical and mechanical properties are independent of humidity factors in the working conditions;
5. Ultra-high molecular weight polyethylene sheets have stable chemical properties and can resist corrosion from various corrosive media such as acids, alkalis, salts, and organic solvents within certain temperature and concentration ranges;
6. Ultra-high molecular weight polyethylene sheets are odorless, non-toxic, non-corrosive, and have physiological inertness and biocompatibility;
7. Non-adhesive;
8. When the molecular weight of high-density polyethylene exceeds 500,000, the embrittlement temperature drops to -140°C. Ultra-high molecular weight polyethylene can even operate under liquid nitrogen, with a service temperature as low as -269°C, while still maintaining certain mechanical strength.
