Ultra-high-molecular-weight polyethylene (UHMWPE):
UHMWPE is polyethylene with a molecular weight numbering in the millions, usually between 3.1 and 5.67 million. The high molecular weight makes it a very tough material, but results in less efficient packing of the chains into the crystal structure as evidenced by densities of less than high density polyethylene (for example, 0.930–0.935 g/cm3). UHMWPE can be made through any catalyst technology, although Ziegler catalysts are most common. Because of its outstanding toughness and its cut, wear and excellent chemical resistance, UHMWPE is used in a diverse range of applications. These include can and bottle handling machine parts, moving parts on weaving machines, bearings, gears, artificial joints, edge protection on ice rinks and butchers' chopping boards. It competes with aramid in bulletproof vests, under the trade names Spectra and Dyneema, and is commonly used for the construction of articular portions of implants used for hip and knee replacements.

At swagath company the latest technology is used for polyurethane covering of various. Rollers up to 6m in length and 2m in diameter. This method is called rotational casting or ribbon flow molding. Production of covered rollers at the minimum time with best surface quality are possible.
We do open casting rollers like bridle roller for steel and aluminum plants on their tension leveler line .
These rollers with various dimensions and different kinds of flat ribbed are used in all industries such as steel, iron, aluminum, wood and textile.
Any size rollers or rolls with metal core or only lining can be manufacture as per customers requirements.
The hardness range: from 20 shore A to 85 shore D.
