Product Description

UHMBR SH Overview

UHMW (Ultra High Molecular Weight Polyethylene) is a common machinable plastic known 

for durability, versatility and cost-effectiveness as well as abrasion, impact and chemical resistances.

UHMW plastic features a molecular weight that ranges from 3.1 million to 100 million grams per mole, 

with an abrasion resistance that continues to improve as molecular weight increases.

Reprocessed UHMW is an eco-friendly and economical alternative to standard virgin UHMW 

that uses a blended version of virgin and recycled UHMW. Reprocessed UHMW is excellent 

for non-food applications and offers all the benefits of standard UHMW at a much more 

cost effective price. Reprocessed UHMW features the same low coefficient of friction as 

standard UHMW while also offering a slightly better wear resistance. Reprocessed UHMW 

is used extensively for chain guides, wear rails, chute liners, truck liners, hopper liners and 

many other applications where excellent wear properties are required. The standard color 

of reprocessed UHMW is black, but also comes in green.



Machinability & Tolerance Warnings:
There is some inherent stresses in the material so if you need tight tolerance parts you may want to 

consider a material such as acetal. Standard diameter tolerance of the rods is ±10% This material can 

be machined and should not shrink due to the machining process. UHMW expands and contracts 

considerably with temperature change. Other materials are available if you need a lower coefficient 

of linear thermal expansion. Call our experts at (888) 423-3902 for more information or questions 

about what materials to use for your application.

Low Coefficient of Friction
Reprocessed UHMW is used in applications where high levels of friction are likely to arise including 

conveyor guard rails, augers and wear strips, belt scrapers, chain guides, and idler rollers. Due to 

an extremely low coefficient of friction, its inherent lubricity minimizes heat-generating friction 

that tends to gradually destroy steel parts, and ensures smooth, noiseless operation.

Self-Lubricating Formula
High durability, low friction and wear resistance are key reasons why reprocessed UHMW is the 

material of choice for a myriad of applications. Reprocessed UHMW offers an extremely low 

coefficient of friction due to a specialized built-in lubricant that replaces unwanted grease 

and oil. It also enhances efficiency and productivity in many applications. Reprocessed 

UHMW's self-lubricating formula helps to extend part life because the internal lubricant 

ensures that parts will not break or need replacement.
