Burachem White 9655/W


Burachem White 9655/W is a PTFE-based gasket sheet a barium sulfate filler. The materialʼs high density creates the optimum conditions for use in applications subject to high mechanical stresses.


  • Minimum cold flow properties
  • High density

Operating range

Pressure: p = 83 bar
  • Continuous operation:
    t = -210 °C ... +260 °C
Recommended surface roughness:
RZ = 12.5 ... 50 µm

Chemical resistance: pH = 0 ... 14
Universal chemical resistance, so resistant to most acids and alkalis. Not suitable for use in hydrogen fluoride, fluorine compounds or in molten alkali metals.
