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
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 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 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.
