Ultra High Molecular Weight Polyethylene (UHMWPE) - PE1000
UHMWPE has a molecular weight of +/- 3,000.000 and has excellent impact strength. (better than other PE), high abrasion resistance and good dielectric properties. Avialble with numerous fillers (Glass, Ceramic, Carbon, Oil) for specific application and as a regenerated (recycled) material. Operating temperature range is -150°C to +90°C.
FEATURES
 High chemical resistance typical of the polyolefins
Shock resistance, good even at low temperature.
High abrasion
resistance.
Low friction coefficient.
Low specific gravity.
Easy machinability
Colour: natural
WEAK POINT
Compared to the engineering plastics it has lower thermal and mechanical properties: tensile stress, flexural and compressive strength, etc. Compared to low molecular weight PE, it is less rigid.
APPLICATION
Mechanical: the low friction coefficient and its non hygroscopicity make it suitable for use as a bearing or mechanical parts with low loads, even when operating in water.
Food contact: physiologically inert, it is approved for food contact by the most important standards. Thanks to this feature, it is widely used for components in food machinery, pumps for liquid food etc.
Electrical: very good dielectric properties, weatherproof.
Chemical: thanks to the high resistance to acids and alkali it is used for components in the chemical
industry.
The graph shows that the higher the molecular weight is, the higher the shock resistance, but that tensile stress decreases.
