  • Product Description
  • UPE is also known as: ultra-high polymer polyethylene

  • Characteristics: excellent wear resistance, good low temperature impact resistance, self-lubricating, non-toxic, water and chemical resistance, heat resistance is better than general PE, and the disadvantage is low heat resistance (heat distortion temperature). The processing formability is poor, the outer surface hardness, rigidity, creep resistance is not as good as general engineering plastics, and the expansion coefficient is too large. UHMWPE has poor fluidity and high viscosity in molten state. It is a rubber-like high-viscosity elastomer. It can only be formed by pressing and sintering at an early stage. It can also be processed by extrusion, injection molding and blow molding. The mechanical properties of UPE sheets are higher than those of ordinary high density polyethylene. It has outstanding impact resistance, stress crack resistance, high temperature creep resistance, low friction coefficient, self-lubricating property, excellent chemical resistance, fatigue resistance, noise damping, and nuclear radiation resistance. The use temperature is 100 to 110 °C. Good cold resistance, can be used at -269 °C. The product with a density of 0.935g/cm3 and a molecular weight of 2 million has a tensile strength at break of 40 MPa, an elongation at break of 350%, a flexural modulus of 600 MPa, and a cantilever beam notched impact. The amount of wear (MPC method) is 20 mm. Similar to polyamide and PTFE, wear resistance exceeds carbon steel, making gears, bearings, bushings, star wheels, valves, pumps, guide rails, sealing packing, equipment lining, sliding plates, artificial joints, etc., ropes, etc.

  • Application: UPE board can replace carbon steel, stainless steel, bronze and other materials for textile, paper, food machinery, transportation, medical, coal, chemical and other departments. Such as the textile industry, such as shuttles, shuttle rods, gears, couplings, sweeping rods, buffer blocks, eccentric blocks, rod bushings, swinging effects and other impact-resistant wear parts. In the paper industry, the cover plate, the wiper plate, the compacting parts, the joints, the sealing shaft of the transmission machinery, the deflecting guide wheel, the filter, etc.; the lining of the hopper, the silo and the chute for the powder material in the transportation industry . UPE panels can be used for a variety of mechanical components, including gears, worm gears, worms, and bearings for food machinery. Pumps, valves, baffles, filter plates in the chemical industry. Medically, it can also be used for heart valves, short surgical parts, artificial joints and birth control implants. Sports skating floors, rolling earth roads, snowboards, and snowmobile parts. The application range is similar to that of polyamide and PTFE. The wear resistance exceeds that of carbon steel. It is used for gears, bearings, bushings, star wheels, valves, pumps, guide rails, sealing packings, equipment linings, sliding plates, artificial joints, etc. Wait.
