Water Blocking Shielding Tape application

By applying a highly efficient water barrier film on the surface of Mylar shielding aluminum foil, the requested functions of water barrier and electromagnetic shielding for electronic signal and data cables are perfectly combined. It`s enabling different shielding and water barrier application requirements for single cores, pairs or bundles. The composite water barrier helps the cable to pass the Bellcore Water Penetration Tests (TR-NWT-000421, 5.4.6.1 and 5.4.6.2).
