Polyethylene adhesive inner tape

PBL-3700 series Polyethylene adhesive inner tape is also called polyethylene adhesive tape or polyethylene tape. It is a roll-shaped anti-corrosion material that is thermally laminated from a rubber layer with butyl rubber as the main component to a substrate layer with polyethylene as the main component. It is also called pipeline anti-corrosion tape. The rubber layer ensures the adhesion, water absorption and sealing of the product; the substrate layer effectively ensures the water permeability, heat aging resistance, tensile strength and impact resistance of the tape as a whole.
