Waterproof yarn is a high-tech product mainly composed of polyester industrial filaments and cross-linked polyacrylic acid expansion materials. Which limits the entry of moisture into the interior of cables. It can be widely used for various processing levels inside optical cables, playing a role in bundling, tightening, and blocking water.

Application

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.

Features

1.Water blocking yarn Less powder loss;
2.Soft and easily dispersed;
3.Certain moisture-proof performance;
4.Low shrinkage (4%)&ultra-low shrinkage (2%);
5.Water absorption 50~100g/g;
