Polyurethane (AU/EU) is known for toughness that outperforms conventional rubber compounds, very high tensile strength and load capacity. It resists abrasion and wear, ozone, and extrusion under high pressure. Service temperature is rated from -65°F (-53.9°C) through 200°F (93.3°C). It should not be specified for service in hot water and steam or prolonged humidity at elevated temperature.

You will find this material specified across press and forming equipment, off-highway equipment, and mining and heavy equipment.
