Detail
Product Introduction
Polyethylene anti-corrosion tape is a coiled anti-corrosion material formed by thermally laminating a rubber layer, primarily composed of butyl rubber, onto a substrate layer mainly made of polyethylene. The rubber layer ensures the product's adhesion, water absorption rate, and sealing performance, while the substrate layer effectively guarantees water permeability resistance, heat aging resistance, tensile strength, and overall impact resistance of the tape. After over a decade of concerted efforts, the polyethylene anti-corrosion adhesive tape produced by our company has reached internationally advanced levels. It is also known as pipeline anti-corrosion tape.
Product Advantages
- Uniform adhesive layer thickness with excellent bonding and sealing performance.
- Strong adhesion between the substrate and adhesive layer, preventing delamination during storage or construction.
- Excellent heat aging resistance and strong ultraviolet resistance.
- High tensile strength and appropriate elongation at break, facilitating both mechanical and manual wrapping.
- A comprehensive anti-corrosion material system, including anti-corrosion tape (inner tape), protective tape (outer tape), joint repair tape, anti-corrosion primer, and construction tools.
Applied range
It is widely used for external corrosion protection of metal pipelines in various pipeline engineering and facilities, including petroleum, natural gas, chemical, power, metallurgy, urban gas pipeline networks, and water supply.
