Product Description
Lennite UHMW-PE is a low friction engineering plastic with excellent chemical resistance and abrasive wear resistance. Lennite 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 Plastics manufacturers Lennite with extremely low levels of residual stress so that it can be machined into complex parts with minimal deformation. It is often used to line or replace abrasion-resistant steel plate in bulk material handling applications when low friction, corrosion resistance, and excellent wear properties are essential. Natural (white) Lennite is FDA compliant for use in food processing machinery.
