HI-ZEX MILLION™ is an ultra-high molecular weight polyethylene that was originally developed by Mitsui Chemicals. The average molecular weight of HI-ZEX MILLION™, ranging from 500,000 to 6,000,000, is incomparably greater than that of ordinary polyethylene. Because of its outstanding properties, HI-ZEX MILLION™ is used in a variety of fields: electronic material, industrial material, medical equipment and food manufacturing, etc.

HI-ZEX MILLION™’s density of 930-950 kg/m3 is one of the lowest among engineering resins, and can decrease the weight of the product. In addition, since HI-ZEX MILLION™ does not absorb moisture, HI-ZEX MILLION™ is not subject to swelling or hydrolysis, and preliminary drying is unnecessary before molding. HI-ZEX MILLION™ has a broad range of grade lineups, including hygienic safety grades conforming to FDA specifications, to meet a variety of needs.

Properties:

-Abrasion resistance:HI-ZEX MILLION™’s abrasion resistance is higher than that of metals such as carbon steel and brass, and is several to more than 20 times as high as that of ordinary polyethylene.

-Impact resistance:The impact strength of polyethylene rises as its molecular weight increases. The impact strength of polyethylene reaches its highest level at a molecular weight of 2,000,000. HI-ZEX MILLION™’s impact resistance is higher than that of other resins and ordinary polyethylene, and it is maintained at extremely low temperatures.

-Self-lubrication:HI-ZEX MILLION™’s low coefficient of friction allows the un-lubricated sliding of parts that are in contact with metal surfaces without frictional seizing. Furthermore, because of its hydrophobic nature, any water-containing slurry of minerals will not deposit on HI-ZEX MILLION™.

-Chemical resistance:HI-ZEX MILLION™ demonstrates excellent chemical resistance and shows high stability against acids and alkalis.

Applications:

UML sheets, screws, snow mobile gears/rails, slug hopper lining, battery separators, artificial limbs, high-strength fibers, Sliding tape
