High Heat Insulation Teflon PTFE Cloth Tape For Sealing & Bundling

High Temp Teflon Tape is made with a polytetrafluoroethylene (PTFE) film as the base material and coated with a high performance silicone pressure sensitive adhesive. This combination results in a tape that has excellent heat resistance, chemical resistance, and low friction properties due to the inherent properties of PTFE.

Compared to pure PTFE film tape, the addition of glass cloth increases tensile strength and tear resistance, and is often used as a reinforcing material to improve the mechanical properties of tapes and other materials, providing a more durable solution for packaging and heat sealing machines.

PTFE cloth tape’s non-stick surface and heat resistance enable industrial manufacturers to reliably perform high-temperature vacuum sealing processes. With high performance of heat resistant, it was usually used for vacuum compression packing / Industry ovens / High temp bending machine / Wire cable bundling / Bakelite abrasive masking protection etc..


Here are some general industries where it can be used:

  • Vacuum bagging composites during autoclave cure
  • Sealing ovens for bonded aircraft component assembly
  • Microwave assisted resin infusion processes
  • Custom vacuum chambers holding vacuum pressure
  • Preventing leaks in industrial heating equipment
  • High temperature composite repair patching
  • Research and development equipment sealing
