Product description

Product Introduction

Product Description: The water blocking yarn consists of industrial polyester filament, macromolecule swelling water absorbing tree ester and adhesive.

It is mainly used for water blocking and filling between optical fiber cable, communication cable, fan-shaped wire core, power cable, submarine cable and other parts.

Features

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.

Applications

It is mainly used for water blocking and filling between optical fiber cables, communication cables, fan-shaped wire cores, power cables, submarine cables, and other parts.
