Fluoroplastic High-strength Adhesive Tape NITOFLON No.923SL

Sold Out


Specially oriented PTFE adhesive tape with excellent tensile strength and flame resistance.

NITOFLON No.923SL is a tape using polytetrafluoroethylene (PTFE) film as base material. Single surface treated and coated with silicone adhesive with excellent heat resistance. The tape exhibits superior features such as desirable electrical properties, heat resistance, chemical resistance and non-adhesiveness.


  • The non-adhesive side exhibits excellent features of polytetrafluoroethylene (PTFE) such as electrical properties, resistance to heat, weather, chemical, and water (water shedding), and non-adhesiveness.
  • Superior tensile strength.
  • Superior flame resistance.
  • Can be used in a wide range of temperature (-60°C - 200°C), however, it may vary according to the use condition.
