Product Details

UHMWPE / UPE (Ultra High Molecular Weight Polyethylene) which is a high density polyethylene of very high molecular weight, the average molecular weight is estimated in the range of 4~9 million.
UHMW-PE is used in a wide variety application. Our main production are UHMWPE Rod, UHMWPE Sheet & UHMWPE Machined Parts with excellent quality and physical properties; also,in various shapes, e.g. Extruded Rod, Extruded Sheet,Extruded Tube & Machined Components according to customer's demand.

Advantages of UHMWPE Sheet
Odourless, tasteless, and nontoxic,
    Has extremely low moisture absorption
    Very low coefficient of friction
    UHMWPE doesn’t become brittle until the temperature gets below −150 °C
    Lubricates itself and is highly abrasion resistant.
    It’s resistant to water, moisture and most chemicals
    It’s resistant to UV radiation, and micro-organisms.
Disadvantages of UHMWPE Sheet
Its melts at around +130 to +136 °C
    Not advisable to use UHMWPE at temperatures exceeding 80 to 100 °C for extended periods of time.
    Under load, UHMWPE will deform continually as long as the stress is present, an effect known as creep.
    Probably unsuitable to being used higher load items or components

How well does UHMWPE Sheet perform?

UHMWPE sheet has an incredible resistance to abrasion. It will outperform almost any engineering plastic for abrasion resistance and is probably one of the best materials for lining chutes and hoppers for products such as sand, aggregate and concrete or any other highly abrasive moving product.

Another important property is it's incredibly low co-efficient of friction. It is one of the lowest of all engineering plastics and will produce components with a very high life span with very low drag, which means very little will stick to it. Its also resistant to many dilute acids, solvents and cleaning agents.

UHMWPE has a maximum continuous operating temperature of plus 90°C and a short term operating temperature of plus 120°C. Its a very tough material, with the highest impact strength of any thermoplastic presently made.

What is UHMWPE Sheet used for?
Because UHMWPE sheet has excellent abrasion resistance it is often used for lining chutes and hoppers in aggressive and highly abrasive environments, which is why you’ll find it at the quarry. Its also found in food production environments where high volumes of containers like cans or bottles need to be guided along conveyors or production lines.

Because it has very low moisture absorption, it is also found in some high demand areas of marine applications. UHMWPE is also sometimes used in some cryogenic components due to its low operating temperature abilities.

Due to its resistance to wear and impact, UHMWPE continues to find increasing industrial applications, including the automotive, manufacturing and bottling sectors.

Machining characteristics

High speed steel tooling is recommended with lots of back rake, side rake and clearances, and a generous nose radius. It can be a also bit of a challenge to clamp UHMWPE parts without distorting them. Also, when drilling, the drill will tend to screw into the sheet material.

This engineering plastic can be machined into virtually anything, from small gears and bearings plates to huge wear guides that until recently were only possible with metals. It not only outperforms metal in abrasion applications, it's also easier to machine and therefore cheaper. This versatile plastic can be milled, planed, sawed and drilled to create a huge variety of parts at a very competitive price. UHMWPE sheet has an exceptionally low coefficient of friction which offers superb sliding properties and is one of the best materials for wear and abrasion resistance. UHMWPE Sheet is tough even at low temperatures, it offers low weight, and is easy to weld.
