Strong Black PE Tape Self-Adhesive Pipe Repair Tape

 Strong Black PE Tape Self-Adhesive Pipe Repair Tape is one of the most important products of Butyl Rubber Pipe Coating. Its most important function is to connect and repair pipe layers.

 XUNDA T300 Joint & Repair Coating System for new pipelines and existing pipeline rehabilitation.

 XUNDA pipeline anticorrosion material selection of high-quality anticorrosion raw materials, through the butyl rubber as the main component of the rubber layer thermal composite to the polyethylene substrate layer of the roll of anticorrosion materials. The butyl rubber ensures the adhesion, water absorption and sealing of the product, while the base material layer effectively ensures the water permeability, heat aging resistance, tensile strength and impact resistance of the tape.

 XUNDA also provides products and services for major corrosion resistant piping systems worldwide, we offer the Xunta brand and OEM services.
