Polyethylene PE 1000 sheet commonly referred to as ultra-high-molecular-weight, UHMW, or UHMWPE, is one of our most popular engineering plastics. It provides excellent resistance to abrasion, chemicals, impact and wear, and offers very low co-efficient of friction. UHMW is also non-toxic, odourless, 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 against ratholing and arching.

One of the most striking properties of UHMW polyethylene is its extremely high abrasion resistance, which is invaluable in many engineering applications. Among all plastics, its wear resistance is the best, and even the regular wear resistance of many metal materials (such as carbon steel, stainless steel, bronze, etc.) is not as good as it. As the molecular weight of polyethylene increases, the material becomes more wear-resistant.
The impact strength of ultra-high molecular weight polyethylene is related to its molecular weight. When the molecular weight is lower than 2 million, the impact strength increases with the increase of the molecular weight, and reaches a peak at about 2 million. After the peak, the impact strength increases with the molecular weight will decline. This is because the molecular chain is abnormal and hinders its photocrystallization, so that there is a large amorphous region in the macromolecule, which can absorb a large impact energy.
UHMWPE is very wear-resistant, has a low coefficient of friction and good self-lubrication, and is an ideal material for bearing bushings, sliders and linings. The use of ultra-high molecular weight polyethylene as the friction part of the equipment can not only improve the wear-resistant life, but also save energy.
Ultra-high molecular weight polyethylene has good chemical corrosion resistance. Except for concentrated nitric acid and concentrated sulfuric acid, it will not be corroded in all lye and acid solutions, and can be used in concentrated hydrochloric acid at a temperature (80°C). It is also stable in <20% nitric acid, <75% sulfuric acid, and it is also stable in water, liquid washing. However, ultra-high molecular weight polyethylene is very easy to swell in aromatic or halogenated compounds (especially under higher temperature conditions), so special attention should be paid during application.
UHMWPE has a very low water absorption rate, it is almost non-absorbent, does not swell in water, and is much less absorbent than nylon.
According to the method of ASTM (load 4.6kg/cm2), the heat distortion temperature is 85℃. Under a small load, the service temperature can reach 90℃. In special cases, it is allowed to use at a higher temperature. High molecular weight polyethylene is a material with excellent toughness, so its low resistance is also very good, and it still has a certain degree of ductility at a low temperature of -269 ° C, and there is no sign of embrittlement.
UHMWPE has excellent electrical properties in a wide temperature range, its volume resistance is 10-18CM, its breakdown voltage is 50KV/mm, and its dielectric constant is 2.3. In a wide temperature and frequency range, its electrical properties change very little. In the heat-resistant temperature range, it is very suitable for use as structural materials in electrical engineering and materials in paper mills.
Non-toxic ultra-high molecular weight polyethylene is tasteless, non-toxic, odorless, non-corrosive, and has physiological circulation and physiological adaptability. The United States Food and Drug Administration (FDA) and the United States Department of Agriculture (USDA) allow it to be used in contact with food and medicines. Its characteristics, especially wear resistance, impact resistance, and self-lubricating properties, are the best among engineering plastics.

Ultra-high molecular weight polyethylene refers to linear structure polyethylene with a molecular weight of more than 3 million. It is an engineering plastic with the best comprehensive performance. Its five properties are wear resistance, impact resistance, corrosion resistance, self-lubrication, and impact energy absorption. There are the best of plastics, known internationally as "amazing materials".
We can manufacture modified and performance-enhanced UHMWPE sheets, including:
Ultra-high molecular weight polyethylene is polyethylene with a molecular weight of more than 1 million. Heat distortion temperature (0.46MPa) 85℃, melting point 130-136℃, it is a thermoplastic engineering plastic with linear structure with excellent comprehensive properties. Its mechanical properties are higher than HDPE, and it has outstanding wear resistance and impact resistance. high temperature resistance, low temperature wear coefficient, stress crack resistance, high temperature creep resistance, low friction coefficient, self-lubrication, excellent chemical corrosion resistance, fatigue resistance, noise damping, nuclear radiation resistance and other excellent properties. Can replace carbon steel, stainless steel, bronze and other materials for textile, paper, food machinery, transportation, medical, coal, chemical and other departments.
Wear resistance ranks first in plastics, and the larger the molecular weight, the higher the wear resistance and impact resistance of the material.
The impact strength is the highest value among existing plastics, even at 70°, there is still a fairly high impact strength.
Has a low friction coefficient and self-lubricating properties, making it highly non-adhesive.
Very low water absorption. Therefore, its physical and mechanical properties are independent of the humidity factor in the working conditions used.
It is chemically stable, and can resist the corrosion of various corrosive media such as acid, alkali, salt and organic solvents within a certain temperature and concentration range.
Odorless, non-toxic, non-corrosive, with physiological circulation and physiological adaptability.
When the molecular weight exceeds 500,000, the embrittlement temperature drops to 140°, and even under the action of liquid nitrogen, the ultra-high molecular weight polyethylene still has a certain mechanical strength when its service temperature can reach -269°.
