New Arrival China Semi-Conductive Cushion Tape For Cable - Semi-conductive Water Blocking Tape – ONE WORLD Detail:

1. Product Introduction

The semi-conductive water blocking tape is made of semi-conductive polyester fiber non-woven fabric, high-speed expansion water-absorbing resin and other materials.
Among them, the semi-conductive base layer is manufactured by uniformly distributing the semi-conductive compound on a relatively flat, temperature-resistant, and high-strength base cloth; the semi-conductive resistive water material uses powdery polymer water-absorbing materials and conductive carbon black. The water material is attached to the base fabric by padding or coating.
The semi-conductive water blocking tape has the function of absorbing water and swelling. It is widely used in the semi-conductive water layer of water-blocking type medium, high and ultra-high voltage power cables and other control and communication cables with shielding requirements, and plays a role of water blocking and shielding.
We have single-sided semi-conductive water blocking tape and double-sided semi-conductive water blocking tape. The single-sided tape is composed of a single layer of semi-conductive polyester fiber non-woven fabric and high-speed expansion water-absorbing resin; the double-sided tape is composed of semi-conductive polyester fiber non-woven fabric, high-speed expansion water absorbing resin, and semi-conductive polyester fiber non-woven fabric in turn. The single-sided tape has better water blocking performance because it has no base cloth barrier.
Our water blocking tape has the following characteristics:
1) The surface is flat, without wrinkles, notches, flashes and other defects;
2) The fiber is evenly distributed, the water blocking powder and the base tape are firmly bonded, without delamination and powder removal;
3) High mechanical strength, easy for wrapping and longitudinal wrapping processing;
4) Strong hygroscopicity, large expansion rate, fast expansion rate, and good gel stability;
5) Good heat resistance, high instant temperature resistance, and the cable can maintain stable performance at instant high temperatures;
6) High chemical stability, no corrosive components, resistant to bacteria and mold erosion.

2. Application

It is suitable for the semi-conductive water layer of water-blocking type medium, high and ultra-high voltage power cables and other control and communication cables with shielding requirements, and plays a role of water blocking and shielding.
