The compound resists many acids, engine and transmission fluids, and petroleum oils and fuels.

Continuous operating temperature is published at -15°F (-26.1°C) to 400°F (204.4°C). Exposure to hot water and steam or ketones and esters will shorten service life.

Common environments for this compound include high-temperature process equipment, aerospace, and chemical processing.
