Material Notes:

Lennite UHMW-PE is a low friction engineering plastic with excellent chemical resistant and abrasive wear resistance. It is widely used in conveyors, packaging machinery, and food processing machinery since it is inherently low friction, wears well, and is not abrasive to mating parts. Westlake manufactures Lennite with extremely low levels of residual stress so it can be machined into complex parts with minimal deformation. Information provided by Westlake Plastics.
