Waterproof Sealing Mastic Tape
Product Description
Waterproof sealing mastic tape is a kind of good shape, durable tape, used together with PVC electrical tape. It can provide special waterproof sealing effects 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°C to 80°C.
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 structures 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 other 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.
Instructions:
1. Clean the surface: Clean the dust and oil on the joint.
2. Remove the paper: Strip off the paper and stretch the tape so that it maintains tensile strength.
3. Winding method: When wrapping, the tape should be stretched so that it is about three quarters of the width before the original stretch, and the object is wrapped in a spiral half overlap.
4. Extrusion attachment: When wrapping the last circle, the tension should be relaxed, and the tail should be pressed for a moment at the end. It is advisable to squeeze the tape at the wrapped place by hand to enhance the adhesion effect. Finally, outside the waterproof tape, it is advisable to wrap two layers of PVC tape in a semi-overlap way as mechanical protection.
