Product Description

Product Name:
Water-blocking Tape


1, Application and Feature: 
It is a combination of tape, yarn, or coating to prevent longitudinal penetration of water into the cable core .The main principle is to use a kind of polymer that can absorb water and quickly form gel to fill the seepage channel through the expansion of hydrogel. It is widely used In optical fiber cable, data cable, telecom cable and control cable.
Proven high performance of swelling and water blocking
Process friendly
REACH and RoHS compliant
