The material holds up against extreme heat and cold, dry heat, and weathering. Continuous operating temperature is published at -80°F (-62.2°C) to 450°F (232.2°C). Applications involving abrasive dynamic service or hydrocarbon fuels and oils call for a different compound.

Maintenance and OEM teams specify it across ovens and heated equipment, medical devices, and pharmaceutical manufacturing.
