PTFE-Encapsulated Silicone is valued for a seamless PTFE jacket over a resilient silicone core and a non-contaminating, non-stick sealing surface. The compound resists wide temperature swings, strong acids and solvents, and steam. Service temperature is rated from -75°F (-59.4°C) through 400°F (204.4°C). Verify compatibility before use with installation over sharp edges or tight-radius dynamic flexing.

Maintenance and OEM teams specify it across food and beverage processing, cryogenic and high-temperature equipment, and pharmaceutical manufacturing.
