Introdução do produto
Water blocking tape or Swelling Tape is a modern high-tech water-blocking material with the function of water-absorbing and expansion, which is composed of polyester fiber non-woven fabric and high-speed swelling water-absorbent resin. The excellent water-blocking performance of the water blocking tape mainly comes from the strong water-absorbing performance of the high-speed expansion water-absorbent resin that is evenly distributed inside the product. The polyester fiber non-woven fabric to which the high-speed expansion water-absorbent resin adheres 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 fabric makes the water blocking tape expand immediately when exposed to water, and the water-blocking performance is effectively guaranteed for our Swelling Tape.
The water blocking tape can be used to coat the core of communication optical cable, communication cable and power cable to play the role of binding and water-blocking. The use of water blocking tape can reduce the infiltration of water and moisture in the optical cable and cable, and improve the service life of the optical cable and cable. Especially for the dry-type optical cable developed in recent years, the water blocking tape replaces the traditional grease, and there is no need for wipes, solvents and cleaners when preparing the connection of optical cable. The connection time of optical cable is greatly shortened, and the weight of the optical cable can be reduced.
We can provide single-sided/double-sided water blocking tape. The single-sided water blocking tape is composed of a single layer of polyester fiber non-woven fabric and high-speed expansion water-absorbing resin; the double-sided water blocking tape is composed of polyester fiber non-woven fabric, high-speed expansion water-absorbing resin and polyester fiber non-woven fabric in turn. The single-sided water blocking tape has better water blocking performance because it has no base cloth to block.
The water blocking tape we provided has the following characteristics:
1) The surface is flat, without wrinkles, notches, flashes.
2) A fibra é distribuída uniformemente, o pó de bloqueio de água e a fita de base estão firmemente ligados, sem delaminação e remoção de pó.
3) Alta resistência mecânica, fácil de enrolar e enrolar longitudinalmente.
4) Forte higroscopicidade, alta altura de expansão, taxa de expansão rápida e boa estabilidade do gel.
5) Good heat resistance, high instantaneous temperature resistance, optical cable and cable can maintain stable performance under instantaneous high temperature.
6) High chemical stability, no corrosive components, resistant to bacterial and fungal erosion.
