This month,we (ONE WORLD) delivered 1 ton of 9000D water blocking yarn and 1 ton of PBT to our customer from Azerbaijan by air.This is the first time we cooperated with the customer. After carefully comparing the technical parameters and prices, we finally reached a cooperation. Now the goods have arrived and I believe that our future cooperation will continue.

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.
PBT has excellent mechanical properties, electrical insulation properties, oil resistance, chemical corrosion resistance, easy shaping and low moisture absorption. It is the most commonly used extruding material for outdoor optical cable loose tubes.
It is suitable for the production of secondary coating loose tube for outdoor communication optical fiber cable.
