WZD Wasserblockierbändern für optische & electri

Water blocking tapes WZD water blocking tapes are the newly developed watertight materials for communications cables. Which was made of non-woven fabrics of terylene fiber and power of super water absorbent resin (SAP). The SAP can absorb large quantities of water. WZD water blocking tapes provides excellent swell rates and swell heights. When the cable was hurt and water enter the wound, the SAP resin absorb water and rapid swell and create a pressure dam within the cable preventing further ingress and migration of water. In conclusion, WZD water blocking tapes provide outstanding water-proof sealing effect for the cables.
