Water Blocking Yarn
Advantages: high speed of absorbing, good expansion rate, high tensile strength, no acid-base, affection of compatibility for cables, heat resistance, chemistry stability, non-corrosiveness etc. Usage: In production of optic cable, it could be used instead of water blocking tape and water blocking factice etc. It’s used in water-proof communicate cables, optic cables, power cable, especially undersea optic cable. It could avoid moisture permeating through cables.
