Water Proofing Mastic Tape
Water Proofing Mastic Tape
Waterproof sealing mastic tape is a kind of tape with good shape variable and durability. It can be used in conjunction with vinyl tape to provide excellent water proofing and sealing effect for cables and pipeline. It is mainly composed of butyl rubber, which demonstrates excellent self-fusing, water proofing and insulation properties. It can provide quick and easy repair and sealing for targets that require waterproofing. It can be used for insulation, waterproof, sealing and protection in communication base stations, communication cable connectors, etc., and the rated service temperature is -40 to 80°C.
Product Features ￭ Excellent material bonding and water proofing performance, easy to install; ￭ Ultralow water absorbability； ￭ Low failure rate and maintenance cost； ￭ High tensile strength, excellent covering； ￭ Quality material, with excellent insulation function； ￭ Suitable for insulation filling and sealing of complex structures, with strong adhesion； ￭ This product can completely isolate the influence of ozone, water and various soil chemical substances； ￭ Especially suitable for cold weather, it can maintain elasticity and good sealing even when in large curvature.
