Ultra-High-Molecular-Weight Polyethylene
UHMWPE are PE types with molecular weights ranging between 1 million g/mol to 10 million g/mol. Standard types are used in the range of 3-5 million g/mol. As the molecular weight increases, wear resistance and impact resistance improve.
PE-UHMW shows the most balanced qualities of all polyethylenes and offers a very good impact resistance even at temperatures as low as negative 200°C.
Characteristic Features:
Best wear resistance of all technical plastics at room temperature, very low friction coefficients,
best sliding properties, very good tension crack resistance, noise reduction, UV resistance.
Applications:
Protective devices, lining technology, general mechanical engineering, conveyor technology, medical technology, protective clothing, sports & leisure supplies.
Processing:
Due to the high molecular weight, the material viscosity also increases, so that PE-UHMW can usually only be processed by either RAM extrusion or pressure sintering. As a result, semi-finished products can be further processed with very low-stress. We are currently working together with our partner, IRPC, to develop a UHMWPE granulate type suitable for injection molding.
