Product details

Application recommendation:

Our water-blocking tapes have an excellent swelling property. When water enters into a cable protected by water-blocking tape, the super absorbent powder within the tape instantly forms a water-blocking gel, that prevents further and more costly damage to the cable.

Water-blocking tape tapes prevent the progression of water deep into many types of critical cable designs.
