PTFE-Encapsulated Silicone is valued for a non-contaminating, non-stick sealing surface and excellent recovery across extreme temperature cycling. This material stands up to nearly all process chemicals, wide temperature swings, and steam. Rated temperature range runs from -75°F (-59.4°C) to 400°F (204.4°C) in continuous service. Applications involving installation over sharp edges or tight-radius dynamic flexing call for a different compound.

It sees regular use in pharmaceutical manufacturing, chemical processing, and cryogenic and high-temperature equipment.
