Technical Data
Waterproof sealing mastic tape is a kind of good shape, durable tape, used together with PVC electrical tape. It can provide special waterproof sealing effect for cables and pipelines. It is mainly composed of butyl rubber, strong self-melting, with excellent waterproof and electrical insulation properties. It can provide quick and simple insulation, repair and sealing for the need of waterproof targets. It is used for waterproof sealing of communication equipment base stations, antennas, feeders and other joints, and the working temperature is -40 ~ 80℃.
Features:
- Excellent waterproof performance
- Comfortable and convenient operation
- Low failure rate and low maintenance cost
- High tensile strength with excellent coating properties
- Suitable for complex insulation, filling, and sealing structures with strong adhesion
- Completely isolated from ozone, water, and various oil chemicals
- Ideal for use in cold weather, maintaining elasticity and good sealing even under bending
Application:
- Power cable accessories, including cold shrinkable cable joints, waterproof joints, and welding joints, used for reliable waterproof sealing
- Waterproofing for facilities in 4G and 5G base station construction, such as antennas, feeders, splitters, and tower amplifiers
- Low voltage insulation and outer sheath repair, suitable for primary insulation recovery for applications up to 1000 volts, including motor lead insulation
- Waterproof sealing of ground wires
- Waterproof sealing and protection for overhead insulated wire joints
- Additional waterproofing and electrical applications, ideal for high-speed rail, maritime environments, and other specialized fields
