PTFE (Polytetrafluoroethylene) coated adhesive tapes are specialized tapes that feature a PTFE coating on a backing material, typically fiberglass, with a pressure-sensitive adhesive on one side. These tapes are widely used in various industrial applications due to their unique combination of non-stick properties, high-temperature resistance, and chemical inertness.

Key Features:

  1. Non-Stick Surface – The PTFE coating provides excellent release properties, making it ideal for applications where adhesion of substances needs to be minimized.
  2. High-Temperature Resistance – These tapes can withstand temperatures ranging from -73°C to 260°C (-100°F to 500°F), making them suitable for high-heat applications.
  3. Chemical Resistance – PTFE is resistant to most chemicals, acids, and solvents, ensuring durability in harsh environments.
  4. Low Friction – The smooth PTFE surface reduces friction, which is beneficial in mechanical and conveyor applications.
  5. Waterproof and Weather-Resistant – They exhibit strong resistance to moisture and environmental conditions.

Types of Adhesives Used:

  • Silicone Adhesive – Offers high-temperature resistance and is commonly used in extreme heat environments.
