  • Water-blocking Tape

Water-blocking Tape

Water-blocking Tape is widely used In optical fiber cable, data cable, telecom cable and control cable.


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
