QV-DB Swelling sealing tape

for multiple occupancy

Self-sealing, nonwoven swelling material, consisting of mechanically preprocessed, heat-fixed, fibre-bonded material, made of PP fibres and special super-waterabsorbent fibres, UV-stabilised.

Geotextile robustness class TL Geok EStB05-3-

Applications

Swelling material, in combination with the Swelling material, in combination with the QAK/V sealing system (WO16), is specially recommended for use in service entries for FTTH, photovoltaic, wind energy and biogas applications etc., where a grease-free seal (e.g. no dripping oil) is required.

Product advantages of swelling material

  • Quick retrosealing
  • Grease-free seal
  • Self-sealing (up to 10 m water column) on contact with water
    - seals immediately against water, dust, smoke and noise
  • Vibration-resistant sealing
  • Resistant to notching and impact
  • No unwanted adhesion to surrounding materials
  • Can be reused several times after swelling material has thoroughly dried out
  • Lightweight.
  • Does not contain any harmful substances
