Self-sealing, nonwoven swelling material, consisting of mechani-cally preprocessed, heat-fixed, fibre-bonded material made of PP fibres and special super- waterabsorbent fibres, UV-stabilised.
Geotextile robustness class TL Geok EStB05-3
Self-adhesive swelling tape QV-DBK consists of swelling sealing tape Article No. WO22.1 QV-DB manufactured with double-sided adhesive tape on one side.
For example when petrolatum-vaseline tapes or old swelling tapes are replaced in the course of refurbishing sealing elements.
QAK/V sealing elements are more suitable (WO16) for service entries in buildings, in the areas of FTTH, photovoltaic, wind energy or bio-gas facilities etc, where a grease-free seal (no dripping oil etc.) is required within the temperature range.
QV-Seal water blocking layer are preferable for applications where requirements demand low weight and high resistance to cuts and burst pressure.
