Supraflon 6435 For a larger view, please mouseover the image.
Supraflon 6435 is a diagonally braided packing of aramid staple fibre with universal silicon grease-free lubricant and PTFE impregnation. Its impregnation combined with excellent cross-sectional tightness offers a good sliding performance.
  • High thermal and chemical resistance
  • Excellent cross-sectional tightness
  • Highly wear resistant
  • Gentle to the shaft
Pressure:

p(pumps) = 20 bar (pumps),
p(valves) = 100 bar

Sliding velocity:
vg(pumps) = 20 m/s,
vg(valves) = 2 m/s

Temperature: t = -100 °C ... +250 °C, steam: +180 °C
Chemical resistance: pH = 1 ... 13

To avoid excessive abrasion at the bearing surface of shafts and casings because of the high strength of the aramid fibre we recommend a surface hardness of 40 ... 60 HRc.
