Description
Water Blocking Tape has an excellent swelling property. When water enters into a cable protected by water blocking tape, the super absorbent polyacrylate swelling powder within the tape instantly forms a water blocking gel, that prevents further and more costly damage to the cable.
Typically used in communication cable as an alternative to flooding or filling compounds…
Characteristics
• Excellent water-blocking performance
