| UHMW®
ULTRATEC® is a truly unique product that meets tough
criteria for products in overcoming harsh environments-exceptional
abrasion resistance, corrosion and impact resistant, low friction
coefficient, repels water, eliminates sparks, reduces noise and
is chemically inert.
ULTRATEC® comes in a wide range of sheets, plates,
boards, custom shaped fabrications, profiles, rods, bars and tubing.
ULTRATEC® is available in a wide selection of colors and thicknesses.
Manufactured to exacting specifications, ULTRATEC®
meets or exceeds the specifications set forth by ASTM D-4020-81
for ultra- high molecular weight polyethylene.
Applications
ULTRATEC® has a wide range of unique properties
to meet harsh environment demands including abrasion, corrosion,
impact, water-absorption and resistance to acids and alkalines.

Characteristics
- top
Exceptionally
High Abrasion Resistance
Case-histories
have proven the superior wearability of ULTRATEC® compared to steel
and its unique ability to resist extreme sliding abrasion.
High Impact Resistance
One of the
unique properties of the product is to maintain its impact resistance
even at extreme temperatures and will even harden with repeated
abuse.
Slippery
The product has a low coefficient
of friction providing a smooth, consistent flow of materials even
in freezing conditions.
Lubricity
The ability of the material to work exceptionally well without
the introduction ofprocessing industry.
Inert
High resistance to most alkalis, acids and industrial chemicals
even at high temperatures. Will not rust.
Repels Water
ULTRATEC®. will not absorb water making it particularly useful in
preventing materials from freezing.
Easily Cleaned - top
The non-stick nature of the material allows easy cleaning and
helps prevent material from bridging or "rat-holing."
Electrical Properties
The material has good electrical properties and eliminates spark
hazards compared to metal products.
FDA/USDA Approved
Odor and taste free, non-corrosive and inert, ULTRATEC® meets government
requirements for direct food contact.
Reduces Noise
When used in noisy environments, tests have shown a significant
drop in the decibel level.
Lightweight
Compared to steel, ULTRATEC® is 1/7 to 1/9 the weight of the
same amount of steel to do the same job.
Economical
Compared to plate or stainless steel, ULTRATEC® is significantly
less expensive and due to its lightweight nature is easy to install,
allows easy retrofitting and its low cost allows protective linings
to be added to new installations and greatly extend wear life.
Design Features -
top
Thanks to its lightweight and easy handling, ULTRATEC®
is an ideal material for retrofitting projects. The product
can be cut shaped, drilled, turned, tapped and machined "Right-On-Site"
using ordinary wood-working tools. ULTRATEC® can even be pop
riveted over old materials.
