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.

Strength is maintained in extremely low temperature

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.

Seizing will not occur

Seizing will not occur

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 metals will not deposit on HI-ZEX MILLION.
