High Impact Strength

Out of all thermoplastics, UHMW-PE retains the toughest resistance to impact, even compared to hard types of steel. Donc, it is commonly used when the material is exposed to repeated shocks or heavy loads.

Faible coefficient de frottement

Because it has a very low friction coefficient of 0.10, UHMW-PE does not stick and reduces friction by itself. It suitably protects conveyor systems, wear strips, and parts made to slide with only a minimum amount of friction.

Top-Notch Abrasion Resistance

UHMW is five times more resistant to wear and abrasion than steel is. That is why polyurethanes are often used in bulk processing, exploitation minière, and packaging lines.

Résistance chimique

Chemicals like acids, alcalis, alcohols, and organic solvents are not able to harm UHMW-PE. It is stable and doesn’t decay in tough industries.

Resistance to Water and Moisture

UHMW stays the same size even when exposed to water, since it hardly absorbs moisture. Neoprene won’t become bigger, degrade, or get weaker when used in humid or underwater conditions.

Meeting FDA and USDA Requirements

It is possible to choose UHMW-PE that has been approved for use with food and beverages. En règle générale, it is found in manufacturing for food processing, bottling, and medical packaging equipment.

Effective Electrical Insulation

Because it has both excellent dielectric strength and insulating abilities, UHMW is used in electronic and electrical insulation.

Reasonable Tensile Strength

It might lack the strength of metals, but UHMW still has a strong tensile strength of between 21 et 30 MPa. It has enough tolerance to pressure and retains flexibility.

Elongation and Flexibility

The material can be stretched very far (entre 300% et 500%) before it breaks. With this property, asphalt separates the road from any unwanted vibrations and shocks.

Low Density

Because it weighs ~0.93–0.94 g/cm³, UHMW is lighter than most plastics as well as water. The advantage of lightweight aluminum is that it is simple to handle and eliminates extra weight in engineering projects.

Low Melting Temperature

UHMW-PE is said to have a melting point of about 130–136°C (266–277°F). As it can’t do high-temperature tasks, thermoforming and machining these materials are simple.

UV Resistance that includes Stabilizers

Since natural UHMW is not UV-resistant, it can suffer damage after long exposure to the sun. Néanmoins, paint makers offer UV-stabilized models (which are often black) for those using paint outdoors.

Choosing and Designing Your Color

Besides natural (blanc) UHMW-PE, you can also buy it in black (UV-protected), bleu (complies with FDA standards), and custom colors to match your needs.
