PTFE Jointing Sheet Planiflon™ B15


  • Modified PTFE resin
  • Barium sulphate filler


Planiflon B15 is a superior performance biaxially orientated PTFE gasketing sheet material with barium sulphate filler. Planiflon B15 is conforms with FDA regulations and it has a very low gas permeability, improved creep properties when compared with conventional PTFE gasketing sheets. Is a general purpose grade for sealing applications across the whole pH range. It is suitable for use with hydrofluoric acid, but not pure liquid hydrogen fluoride. It can be also used with alkalis, solvents, fuels, water, steam and chlorine.


Planiflon™ B15 is suitable for industrial applications for sealing the flanges and has the following certificates:

  • DVGW
  • FDA
