Ultra High Molecular Weight Polyethylene (UHMW-PE)

Ultra High Molecular Weight Polyethylene (UHMW-PE) is a thermoplastic, characterised by its high strength to density ratio.

The density of UHMW-PE can range from 0.93 to 0.97 g/cm3 and is relatively low compared to other thermoplastics. It can withstand temperatures up to 120°C for short periods, and 80°C continuously (up to 110°C continuous for special high temperature grades).

This category of thermoplastic is characterised by:

- Excellent resistance to alternating strain

- Very good resistance to wear and abrasion

- Self-lubricated

- Low coefficient of friction

- Very low moisture absorption

- Excellent impact resistance, even at low temperatures (-40°C)

- Excellent chemical resistance

- Good resistance to high-energy radiation

- Electrically insulating.
