The compound resists strong acids and solvents, steam, and nearly all process chemicals. Continuous operating temperature is published at -75°F (-59.4°C) to 400°F (204.4°C). It is not the right choice where installation over sharp edges or tight-radius dynamic flexing are present.
You will find this material specified across pharmaceutical manufacturing, cryogenic and high-temperature equipment, and chemical processing.
