Product Type: Plastics

Pactene is a brand of Ultra High Molecular Weight Polyethylene (UHMWPE), a useful plastic for many industrial and engineering needs.

It has the following properties:

  • Molecular weight approximately 4 million (Light Diffusion Method)
  • Low specific weight 0.94g/cm3
  • Extremely high notch impact strength
  • High Pactene (Ultra High Molecular Weight Polyethylene)elasticity
  • Chemical resistance to most corrosive agents
  • Self lubricating
  • Unusually low abrasion guarantees long life
  • Water repellent
  • Favourable electrical properties permit many uses in the manufacture of electrical devices, especially high voltage and high frequency devices
  • No sticking or freezing to the surface
  • Physiologically harmless, as used in food industry
  • Stable to -260oC Used in cryogenics and freezing.
  • No deformation caused by swelling

There are also several variations to Pactene, which include pile driver grade, porous grade, glass bead filled for extreme compression and abrasion resistance, anti-static grade, flame resistant grade, as well as assorted colours available on quote.
