UHMW Polyethylene Sheet

Lightweight & FDA compliant

UHMW Sheet and UHMW Rod

UHMW Polyethylene material is used frequently in a self lubricating bearing surface or slide type application. In fact, many of our clients refer to UHMW as ‘machinable solid wax‘ sheet. The wear resistance of this awesome plastic will impress you, as it is the most wear resistant of any unfilled material available.UHMW Polyethylene Timing Roller

Resistant to most common chemicals. Commonly replaces aluminum, Acetals, and Nylons. Used frequently in Food and Dairy Processing, Material  Handling, Fluid Handling, and Automotive. UHMW is great for wear strips, rub rails, guides, conveyor parts, feed screws, and many more applications.

UHMW Rod is machined to make pulleys, wheels, and washers. UHMW sheet is machined to produce FDA approved slip surfaces, food process fixtures, and scrapers. Some popular brand or trade names are Polystone® M, Lennite®, Tivar®, Duravar®, Gardur®, Solidur®, Polyslick®, UHMV®, Polyfend®, and Durasurf®.

We stock a very large inventory of UHMW performance plastic sheets and rods.

Other Plastic Materials

Why you should use UHMW-PE :

  • Very low specific gravity (floats in water)
  • Superior wear resistanceVery low moisture Absorption
  • High chemical resistance
  • Very low cost vs. physical properties

This material is excellent wearing and very abrasion resistant – one of the best materials made for these properties. Promotes the flow of bulk material (sand, soy beans, coal, ect). Superior material for wear strip, conveyor rails, slide plate, wear pads.

  • Very low moisture absorption
  • FDA, USDA and 3-A dairy compliant
  • Superior wear resistance
  • Chemically resistant to chlorine and caustic/acidic cleaning agents
  • Offers excellent strength, rigidity and machinability

UHMW is ITAR compliant, and UHMW is RoHS compliant

Frequently used in:

  • Food, Dairy and Packaging equipment
  • Timing screws, wear and slide machined parts
  • Star wheels, idler sprockets and guide rails
  • FDA and 3-A approved material for Scraper blades
  • Hopper, chute lining, feeder lines and wear plates
