Polyethylene (PE)
Polyethylene is well known in the polymer family and is often referred to as PE. It has an extremely low coefficient of friction, good
chemical and corrosion resistance with excellent impact strength making it an extremely adaptive thermoplastic. Polyethylene is available
in various grades, offering different properties.
