Ultra high molecular weight polyethylene is a thermoplastic engineering plastic with a linear structure, and its production method and molecular structure are basically similar to high-density polyethylene; Low pressure polymerization, slurry synthesis, and gas-phase synthesis can be used, and the control of molecular weight depends on changing the catalyst composition ratio, adding modifiers, and adjusting process parameters. UHMWPE is the abbreviation for ultra-high molecular weight polyethylene.
Ultra high molecular weight polyethylene is in powder form, with a density of 0936~0.964g/cm. It is non-toxic, not easy to absorb water, not easy to adhere, and has no surface attraction; The mechanical and chemical properties are unique, almost concentrating the advantages of various plastics. It has unparalleled wear resistance, self-lubricating properties, and noise attenuation compared to ordinary polyethylene and other engineering plastics; Resistance to impact, low temperature resistance, and low temperature impact; High temperature creep resistance, good thermal stability, melting point temperature of 190~210 ℃, hot deformation temperature of 85 ℃ (at 046MPa), and melt flow rate close to zero; Good cold resistance, with a brittle temperature below 140 ℃; The tensile strength can reach up to 392MPa;
