    Product Introduction

    The water-blocking tape is a modern high-tech water-blocking material that is composed of polyester fiber non-woven fabric and high-speed expansion water-absorbing resin, and has the function of water-absorbing expansion. The excellent water blocking performance of then tape mainly comes from the strong water absorption performance of the high-speed expansion water-absorbing resin that is evenly distributed inside the product. The polyester fiber non-woven fabric adhered to the high-speed swelling water-absorbing resin ensures that the water-blocking tape has sufficient tensile strength and good longitudinal elongation. At the same time, the good permeability of polyester fiber non-woven fabrics effectively guarantees the ability of water blocking tape products to swell and block water immediately when exposed to water.

    The water-blocking tape can be used for wrapping and longitudinal wrapping of communication optical cables and various water-blocking cable cores to play the role of binding and water blocking. The use of water blocking tape can reduce the penetration of water and moisture in the optical cables and cables, and improve the working life of the optical cables and cables. Especially for dry-type optical cables developed in recent years, the water-blocking tape replaces the traditional grease, and there is no need for wipes, solvents and cleaners in the preparation of the optical cable connection, the optical cable connection time is greatly shortened, and the weight of the optical cable can be reduced.
    We can provide single-sided water blocking tape and double-sided water blocking tape. The single-sided tape is composed of a single layer of polyester fiber non-woven fabric and high-speed expansion water-absorbing resin; the double-sided tape is composed of polyester fiber non-woven fabric, high-speed expansion water-absorbing resin and polyester fiber non-woven fabric in turn.

    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.

    Application

    It is suitable for wrapping or longitudinal wrapping of communication optical cables and water-blocking cable cores.
