UHMWPE (Ultra High Molecular Weight Polyethylene)

UHMWPE are PE types with a molecular weight starting at 1 million g./mol. and going up to 10 million g./mol.  Standard types typically fall within a range of 3-5 million g./mol.  Higher molecular weight improves, in particular, the resistance to wear and tear, as well as the impact strength of the material.   

This material demonstrates a well-balanced property profile encompassing all PE materials and has excellent impact resistance, even at temperatures of up to negative 200°C.

Properties:
  1. Better impact resistance than technical plastics at room temperature
  2. Very low coefficient of sliding friction
  3. Best sliding properties
  4. Excellent stress crack resistance
  5. Noise dampening/ noise reduction
  6. UV-resistant
Areas of Application:
  1. Protective equipment, lining technology
  2. General engineering sectors
  3. Conveyor technology
  4. Medical technology
  5. Sport and recreational applications
Processing:

Due to the high molecular weight of the product, the material viscosity is also higher, which means that UHMWPE can usually only be processed through the RAM-extrusion process.  Injection molding and screw extrusion processing are both not possible.   Semi-finished products for additional machining can be produced with low tension.
