Polyurethane (AU/EU) is specified here for toughness that outperforms conventional rubber compounds and outstanding extrusion resistance at elevated pressure. It resists ozone, petroleum oils, and impact and shock loading. Applications involving hot water and steam or prolonged humidity at elevated temperature call for a different compound.

Typical settings include off-highway equipment, mining and heavy equipment, and hydraulic cylinders.
