Fluoroplastic High-strength Adhesive Tape NITOFLON No.923UL

Sold Out


For roll wrapping of polyethylene laminators, etc.

NITOFLON No.923UL is a tape using NITOFLON No.920UL (specially oriented polytetrafluoroethylene film) as base material. Single surface treated and coated with a silicone adhesive that has a high heat resistance. The tape exhibits excellent features such as electrical properties, heat resistance, chemical resistance and non-adhesiveness.


  • The non-adhesive side exhibits excellent characteristics of polytetrafluoroethylene such as electrical characteristics, resistance to weather, chemical, and water (water-shedding), and non-adhesiveness.
  • Superior tensile strength.
  • Superior flame resistance.

  • For roll wrapping of polyethylene laminators (Suitable for laminations made in a relatively short amount of time or for thin laminates as changing tapes is simple).
  • For endless belts of polyethylene laminators (Time for changing tapes upon dimensional change of laminated products can be shortened by making a double-layered endless belt by bonding the adhesive sides of No.923S together, or, depending on application, with NITOFLON No.923UL or 923SL).
  • For insulation of coils as a class H insulating material.
  • Can be laminated with metals, plastics and ceramics as general sliding materials.
