In addition to its outstanding technical fire safety properties, the new ZZ penetration seal foam 2K NE is particularly characterised by its easy processing. It can be used as a mixed penetration seal (EI90), as well as a pure cable penetration seal (EI90/EI120).
The optimal coordination of the beginning of the reaction and hardening enables sufficiently long work interruptions for the user, as well as fast work progress.
Thanks to the high viscosity, the user does not have to deal with foam running out of the penetration seal. After hardening, the permanently elastic structure of the penetration seal enables easy reconfiguration.
