QV-DBK Swelling sealing tape

QV-DBK swelling sealing tape

self-adhesive

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

Applications: QV-DBK swelling sealing tape

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.

Application:

For sealing cushions and cable sealing

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.
