Expect good resistance to strong acids and solvents, steam, and wide temperature swings. That behavior comes from the compound itself: PTFE-Encapsulated Silicone is valued for chemical inertness of PTFE with the wide temperature range of silicone and a non-contaminating, non-stick sealing surface. Service temperature is rated from -75°F (-59.4°C) through 400°F (204.4°C).

You will find this material specified across food and beverage processing, pharmaceutical manufacturing, and chemical processing.
