POLYETHYLENE (PE)

Polyethylene (PE) is a material with excellent shock absorbing and bending qualities; it wears very little and has good slide characteristics.

It can support temperatures of up to 80ºC, without suffering excessive mechanical strain and up to -200ºC, without breaking.

It has very low thermal conductivity.

It is waterproof and does not swell.

It has self-lubricating properties, particularly in dry sliding friction with metals, such as: steel, brass, copper.
