Film laminated water blocking 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, polyester film and high-speed swelling water-absorbent resin. The excellent water-blocking performance of the film laminated 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 and polyester film to which the high-speed expansion water-absorbent resin adheres ensures that the film laminated water blocking tape has sufficient tensile strength and good longitudinal elongation. Compared with ordinary water blocking tape, the film laminated water blocking tape has higher tensile strength due to the composite of high-strength polyester film, and is more suitable for high-speed wrapping and longitudinal wrapping. At the same time, due to the use of polyester film, when used for the coating of optical fiber cable and cable products filled with ointment in the cable core, it can prevent the penetration of the ointment in the cable core.
The film laminated water blocking tape can be used to coat the core of communication optical fiber cable, communication cable and power cable to play the role of bundling and water blocking. It is especially suitable for the cable core filled with ointment, and can also play a role in preventing the penetration of the ointment. The use of film laminated water blocking tape can reduce the infiltration of water and moisture in the optical fiber cable and cable, and improve the service life of the optical fiber cable and cable.
We can provide single-sided/double-sided film laminated water blocking tape. The single-sided film laminated water blocking tape is composed of polyester film, high speed expansion water-absorbent resin, and polyester fiber non-woven fabric in turn; the double-sided film laminated water blocking tape is composed of polyester film, polyester fiber non-woven fabric, high speed expansion water-absorbent resin, and polyester fiber non-woven fabric in turn.
The film laminated water blocking tape we provided has the following characteristics:
1)The surface is flat, without wrinkles, notches, flashes.
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, high expansion height, fast expansion rate, and good gel stability.
5)Good heat resistance, high instantaneous temperature resistance, optical fiber cable and cable can maintain stable performance under instantaneous high temperature.
6)High chemical stability, no corrosive components, resistant to bacterial and fungal erosion.
Mainly used to coat the core of communication optical fiber cable, communication cable and power cable to play the role of bundling and water blocking.
