1. Name: 3-Ply anti corrosion tape
2. Material: It is a kind of tape anticorrosion material formed by extruding polyethylene base membrane and two butyl rubber adhesive layers and the outer tape is made up by an adhesive layer that is covered thermally on the former.
3. Usage: the pipework of oil and natural gas transportation, petrochemical industry, electric power, metallurgy, urban natural gas network of pipes, the outside anticorrosion project of the metal pipes involved as well as the outside anticorrosion project of the underground and overhead metallic conduit of the works of petrochemical industry, natural gas and coal transportation.
4. Feature:
1). Containing adhesive layer of proper thickness, it is of super healing and insulating performance.
2). The binding force between the backing material and adhesive layer is great, which will prevent degumming.
3). It is of high thermal ageing resistance and UV resistance.
4). It has high tensile strength and appropriate elongation at break, which makes the mechanical and manual wrap easier.
5). It has varieties, specifications, and colors of all kinds, including anticorrosion tape (inner tape), protective tape (outer tape), joint wrap tape, etch primer as well as the necessary tools.
