As a material, Polyurethane (AU/EU) is known for exceptional abrasion resistance and outstanding extrusion resistance at elevated pressure. The compound resists extrusion under high pressure, abrasion and wear, and impact and shock loading. It is not the right choice where prolonged humidity at elevated temperature or hot water and steam are present.

It sees regular use in hydraulic cylinders, mining and heavy equipment, and off-highway equipment.
