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
● Waterproof performance is particularly excellent;
● Comfortable and convenient operation;
● Low failure rate and low maintenance cost
● High tensile strength, excellent coating property;
● Suitable for complex structure of insulation, filling, sealing, with strong adhesion;
● This product can be completely isolated from ozone, water and various oil chemicals;
● Especially suitable for use in cold weather, even in the bending degree can maintain elasticity and
good sealing.
Application
● Power cable accessories such as cold shrinkable cable joint, waterproof joint,
welding joint, etc., used as waterproof sealing;
● Used for waterproofing of facilities in 4G and 5G base station construction of
communication equipment, such as antenna, feeder, splitter, tower amplifier, etc.
● Low voltage insulation and outer sheath repair, suitable for 1000 volts and below
the main insulation recovery, suitable for 1000 volts and below the motor lead
insulation;
● Waterproof sealing of ground wire;
● Waterproof sealing and protection of overhead insulated wire joint;
● Other applications are related to electricity and waterproofing, such as high-speed
rail, ships and other fields.
