ARPLEX® Ultra High Molecular Weight Polyethylene (UHMW-PE)
Ultra High Molecular Weight Polyethylene is a linear, high density
polymer which, due to its extremely high molecular weight exhibits
unique abrasion resistance, corrosion resistance and self-lubrication
ARPLEX® is used in a wide variety industries with applications
ranging from chute liners to wear strips. Products manufactured from
ARPLEX® help to reduce maintenance expenses, part replacement costs and
downtime because of its long wear-life.
ARPLEX® products also help to protect the integrity of original
equipment, extending equipment wear-life as well. ARPLEX® grades of
ultra high molecular weight (UHMW) polyethylene are tough wear resistant
materials that combine abrasion resistant properties with low
coefficients of friction. These self-lubricating polymers resist wear,
friction and corrosion. ARPLEX® cuts maintenance costs, energy
consumption, and offers chemical resistance thereby extending equipment
life in a wide variety of industries. With a working temperature range
of -60° to 180°F ARPLEX® is an excellent solution in many chute, truck
bed liner and hopper applications.

The St. Lawrence North American Fabrication Facility has the advanced
fabrication equipment, products, people, and expertise to provide
technological solutions for the most challenging wear problems.
ARPLEX®-V (White) is our most popular grade of polyethylene. Produced
from pure, 100% virgin UHMW-PE resin, ARPLEX®-V is accepted by the USDA
and FDA for use in food and pharmaceutical processing equipment. With an
average molecular weight of 4 million ARPLEX®-V performs well in wear
applications at temperatures up to 120ºF.
ARPLEX®-R (Green) is produced from recycled UHMWPE mixed with a green
pigment. ARPLEX®-R is an inexpensive general purpose grade with an
average molecular weight of 4 million. It is ideal for many wear
applications in material handling systems and storage containers.
ARPLEX® VX-AR (Grey) is a cross-linked, UV Stabilized, Self-Lubricating,
special purpose UHMW-PE grade. This chemically improved material has a
molecular weight of 6 million and exhibits wear resistant qualities
* Industry standard testing method using slurry of 60% aluminum oxide and 40% water at a rotation speed of 1750 rpm for 2 hours. Results indicate the ability of each material, in relation to Natural (=100), to resist abrasion under typical UHMW-PE applications. A lower number indicates better abrasion resistance
