Water Blocking Yarn
Water Blocking Yarn
Water Blocking Yarns are used in optical, copper telephone, data cable and power cable as cable components. Yarns are used as fillers in power cables to provide a primary pressure block and to prevent water ingress and migration in fiber optical cables. When water enters into a cable protected by water blocking yarns, the super-absorbent component within the yarn instantly forms a water blocking gel. The yarn will swell to approximately three times as its dry size.
