PE 1000 - Polyethylene 1000

Polyethylene with a molecular weight of +/- 1000.000 with excellent impact strength. PE 1000 is less rigid and has a higher shock resistance than the low molecular weight polyethylene and it is therefore more suitable for applications subject to continuous shocks.

FEATURES

  • Shock resistance, good even at low temperatures High chemical resistance typical of the polyolefins
  • 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

  • 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.
  • chemical: thanks to the high resistance to acids and alkali it is used for components in the chemical industry
  • electrical : very good dielectric properties, weatherproof
  • 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

SHOCK RESISTANCE COMPARISON

The graph shows that the higher the molecular weight is, the higher the shock resistance, but that tensile stress decreases.

Yellow: tensile stress
Grey: ball idententation hardness
