The compound resists strong acids and solvents, wide temperature swings, and steam. PTFE-Encapsulated Silicone is known for chemical inertness of PTFE with the wide temperature range of silicone and a seamless PTFE jacket over a resilient silicone core. Rated temperature range runs from -75°F (-59.4°C) to 400°F (204.4°C) in continuous service. It should not be specified for service in tight-radius dynamic flexing or installation over sharp edges.

Common environments for this compound include pharmaceutical manufacturing, cryogenic and high-temperature equipment, and chemical processing.
