The material holds up against ozone, abrasion and wear, and impact and shock loading. Polyurethane (AU/EU) is widely chosen for toughness that outperforms conventional rubber compounds and outstanding extrusion resistance at elevated pressure. The material carries a published service range of -65°F (-53.9°C) to 200°F (93.3°C).

Typical settings include off-highway equipment, mining and heavy equipment, and high-pressure fluid power.
