Polyurethane (AU/EU) is specified here for outstanding extrusion resistance at elevated pressure and exceptional abrasion resistance. It resists ozone, petroleum oils, and impact and shock loading. The material carries a published service range of -65°F (-53.9°C) to 200°F (93.3°C). It is not the right choice where hot water and steam or acids and bases are present.
Common environments for this compound include construction machinery, press and forming equipment, and off-highway equipment.
