Summary

HI-ZEX MILLION™ is Ultra-high Molecular Weight Polyethylene, Mitsui Chemicals originally developed. The average molecular weight of HI-ZEX MILLION™, ranging from 500,000 to 6,000,000, is incomparably greater than the ordinary polyethylene. Because of the its excellent properties, HI-ZEX MILLION™ is used in various fields ; an electronic material, industrial material, medical equipment, and food manufacturing, etc.

HI-ZEX MILLION™’s density of 930-950kg/m3, is one of the lowest among engineering resins, can decrease the weight of the product. Furthermore, 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 a grade lineup, including hygienic safety grades conforming to FDA specifications, to meet varied needs.

Properties

Abrasion resistance

HI-ZEX MILLION™’s abrasion resistance is higher than that of such metals 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 the highest level at the 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 in extremely low temperature.

Self-lubrication

HI-ZEX MILLION™’s low coefficient of friction allows un-lubricated sliding of parts 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 highly stable against acids and alkalis.

Applications

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