  • Higher dielectric strength - better arc resistance
  • Lower elongation
  • Lower porosity - reduced permeability
  • Smoother surface - reduced skive lines
  • High tensile strength
  • Reduced cold flow - less creep
  • Very low moisture absorption
  • Light transmission and transparency



N/A The outstanding properties of PTFE make FluoroCal® Tapes an ideal choice for such applications as dielectric tape, high insulation in electrical components, roll wrapping, composite parts release liner, guide rails, linear bearings and chute liners. FluoroCal® with a silicone adhesive also offers the greatest flexibility in application due to its broad temperature and chemical resistance.
  • P / S tape backing
  • Metallized microwave antennas
  • High frequency "HF" microwave printed circuit substrates
  • Flexible liner for transfer systems
  • Seal & gasket designs where low creep is required
  • Tank liner where film can be welded to create needed shapes
  • Containers for chemicals used in the semiconductor industry where high purity is required
  • Pharmaceutical packaging/lamination
