Features

Burachem Brown 9655/R is a PTFE-based sealing material, filled with silica. Compared to conventional PTFE, this gasket material is suitable for considerably higher pressure and temperature applications. Ideal for standardisation because of the chemical and mechanical characteristics.

Advantages

  • Excellent chemical and mechanical resistance
  • Very low gas leakage (complies with German Fugitive Emission Regulation TA-Luft)
  • Minimized cold-flow and creep behaviour
  • No ageing

Operating range

Pressure: p = Vacuum ... 83 bar
Temperature: t = -210 °C … +260 °C
Chemical resistance: pH = 0 … 14

Resistant throughout the complete pH range as well as against concentrated acids
Not suitable for fluorine-hydrogens, fluorine-compounds or molten alkali metals (except hydroflourides).

Standards and approvals

  • FDA 21CFR 177.1550
