Water swellable non conductive tape

Features of LongVision water blocking tape:

1, Fine and uniform appearance, with certain mechanical strength, benefits the cable finishing process;

2, High quality, no separation and dust when used in the cable production line;

3, Excellent performance of swelling speed, swelling height and the stability of gel after swelling.

4, Good thermal stability, no matter long-term or short-term

5, Good chemical stability, resistance to the erosion of bacteria and mycete

6, Compatibility to other cable materials.

7, Sea grade water swellable table is available upon your request

8, There are Double-side Water Swellable Tape and Single-side Water Swellable Tape, both are non-conductive.

Application: Water swelling, shielding, isolation for power cable, telecommunication cable and optical fibre cable
