Professional China Water Blocking Yarn - Water blocking yarn – Siber Detail:

SIBER 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.

Aramid fibers are a class of heat resistant and strong synthetic fibers. They are used in aerospace and military applications, for ballistic rated body armor fabric and ballistic composites, in bicycle tires, and as an asbestos substitute. They are fibers in which the chain molecules are highly oriented along the fiber axis, so the strength of the chemical bond can be exploited.
