As a material, PTFE-Encapsulated Silicone delivers a non-contaminating, non-stick sealing surface and chemical inertness of PTFE with the wide temperature range of silicone. Expect good resistance to steam, nearly all process chemicals, and wide temperature swings. Published continuous service range is -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.
