Non conductive water blocking tape is an efficient waterproof, moisture-proof and corrosion-proof protective material for cables and buildings. Non woven water blocking tape have unique advantages in specific occasions due to their good air permeability and water absorption. According to the use, non-conductive water-blocking cable tapes can be divided into power cable, communication cable, submarine cable, etc.
Non conductive water blocking tape are electrically insulating and non-conductive, and can effectively avoid safety accidents caused by electrical problems such as short circuits and leakage in cables. It usually uses new polymer materials (such as EPDM, SBR, CR, etc.) as the base tape, and is made of adhesives, protective films, inks and other ingredients, and has good flexibility and strength.
Non conductive water blocking tape are mainly used for waterproof sealing at the joints between buildings or their components, such as basements, kitchens, bathrooms and pools, to ensure the safety of building structures and the health of living environments. In the fields of electricity, communications, etc., non-conductive water-blocking tapes are widely used for waterproof, moisture-proof and corrosion-proof protection of cables, improving the safety performance and service life of cables.
Application
It is used for cable conductor surface and outer layer of insulator, playing a role of insulation and water blocking.
