The single-sided and double-sided laminated water blocking tape composed of polyester film, highly water-swellable material and polyester fiber nonwoven fabric. This structure makes the water-blocking tape waterproof on one or both sides. It is used in situations where waterproofing is required on one or both sides. For example, in scenes such as wall waterproofing and roof waterproofing, the single-sided laminated water-blocking tape can effectively prevent moisture from penetrating from one side while maintaining the structural integrity and functionality of the other side.
Or in underground projects such as basements and underground garages, the double-sided water blocking tape can effectively prevent moisture from penetrating from both sides, ensuring the stability and safety of the underground structure. In addition, the double-sided laminated water-blocking tape is also suitable for some occasions with high requirements for waterproofing, such as bridges, tunnels and other waterproofing projects.
Application
It is suitable for wrapping the conductor and insulation surface of power cables to play a double water-blocking role. It used on the outside of the core of optical cables and communication cables filled with jelly, with the polyester film surface inside, which can prevent the jelly from penetrating and ensure the water-blocking performance.
