It resists aromatic hydrocarbons, chlorinated solvents, and aggressive chemicals. Published continuous service range is -15°F (-26.1°C) to 400°F (204.4°C). Applications involving low-molecular-weight organic acids or hot water and steam call for a different compound.

It sees regular use in chemical processing, automotive fuel systems, and high-temperature process equipment.
