Polyethylene PE 1000 sheet, commonly referred to as ultra-high-molecular-weight polyethylene (UHMW or UHMWPE), is one of the most popular engineering plastics. It provides excellent resistance to abrasion, chemicals, impact, and wear, and offers a very low coefficient of friction. UHMW is also non-toxic, odorless, and is highly resistant to moisture.
UHMW plastic sheet is commonly machined into wear strips, chain guides, and change parts, and is a popular engineering plastic in food processing and bottling operations. Specific grades of PE1000 are also used in bulk material handling applications to line chutes, hoppers, and dump trucks, helping to improve product flow and prevent issues like ratholing and arching.

Features extremely high abrasion resistance, which is invaluable in engineering. Among all plastics, its wear resistance is unmatched, outperforming metals like carbon steel, stainless steel, and bronze. Wear resistance increases with higher molecular weight.
Impact strength peaks around a molecular weight of 2 million. Its large amorphous region effectively absorbs high impact energy, preventing cracks even under heavy strain.
Highly wear-resistant with a low coefficient of friction and excellent self-lubrication. Ideal for bearing bushings, sliders, and linings, saving energy in dynamic equipment applications.
Resistant to chemical corrosion; stable in all lye and acid solutions (except concentrated nitric/sulfuric acid). Stable in concentrated hydrochloric acid at 80°C, <20% nitric acid, <75% sulfuric acid, and liquid washing detergents. Note: Swells in aromatic or halogenated compounds under elevated temperatures.
Extremely low water absorption rate. It is practically non-absorbent, does not swell in water, and offers significantly lower absorption rates compared to nylon.
Heat distortion temperature is 85°C (under 4.6kg/cm² load). Service temperature can reach 90°C under light loads. Retains excellent toughness and ductility at extremely low temperatures down to -269°C without embrittlement.
Maintains outstanding electrical properties across a wide temperature range. Volume resistance is 10-18CM, breakdown voltage is 50KV/mm, and dielectric constant is 2.3. Very stable under temperature and frequency shifts.
Odorless, tasteless, non-toxic, and non-corrosive, offering physiological compatibility. Compliant with the FDA and USDA standards for direct food and medicine contact.
