The material holds up against extrusion under high pressure, ozone, and impact and shock loading. The material carries a published service range of -65°F (-53.9°C) to 200°F (93.3°C).

You will find this material specified across press and forming equipment, high-pressure fluid power, and hydraulic cylinders.
