    Product Introduction

    Water blocking yarn is a high-tech water blocking product made mainly from polyester industrial filament compounded with cross-linked polyacrylic intumescent to restrict the entry of water into the interior of optic cable or cable. Water blocking yarn can be widely used in various processing layers inside the optical cable and cable, and plays the role of bundling, tightening and water blocking.

    Water blocking yarn is a water-swelling yarn with low price. When used in optical cable, they are easy to splice and eliminate the need for cleaning grease in optical fiber splices.

    The mechanism of the water blocking yarn is that when the water penetrating into the cable and contact with the water-absorbing resin in the water blocking yarn, the water-absorbing resin rapidly absorbs water and swells, filling the gap between the cable and the optical cable, thus preventing further longitudinal and radial flow of water in the cable or optical cable to achieve the purpose of water blocking.

    We can provide high-quality water-blocking yarn with the following characteristics:
    1) Even thickness of water-blocking yarn, even and non-dislodging water-absorbing resin on the yarn, no bonding between layers.
    2) With a special winding machine, the rolled water-blocking yarn is evenly arranged, tight and non-loose.
    3) High water absorption, high tensile strength, acid and alkali free, non corrosive.
    4) With good swelling rate and swelling rate, the water blocking yarn can reach a certain swelling ratio in a short period of time.
    5) Good compatibility with other materials in optical cable and cable.

    Application

    Mainly used inside optical cable and cable interior, it plays the role of bundling cable core and blocking water.
