UHMWPE is polyethylene with a molecular weight numbering in the millions, usually between 3.1 and 5.*7 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.****0.**5 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.

UHMWPE used for the construction of articular portions of implants used for hip and knee replacements. As fiber, it competes with aramid in bulletproof vests.

Outstanding features of UHMWPE sheet:

1. Superior wear resistance, seven times wear resistance than steel, four times than PTFE.

2. Excellent high anti-impact resistance, two times impact resistance than PC, five times than ABS.

3. Good self-lubrication, the same as PTFE, better than steel and brass appended lubricating oil.

4. Good anti-corrosion resistance, it has very stable chemicals property and can endure the corrosion of all kinds corrosive  medium and organic solvent in certain rang of temperature and humidity.

5. Very high-inadhesion resistance, the surface of product hardly affix other material.

6. Very high-impact resistance, ten times impact resistance than PA*6, eight times than PTFE.

7. Good low temperature resistance, in liquefied nitrogen (- **6), it still has the prolongation, few other materials can reach to this performance.

8. Non-toxic and clean property, UHMW-PE, which is the material that Food and Drug Administration (FDA) and United States Department of Agriculture (ASDA) permit to apply in food and medicine fields.
