What is duct tape?
The duct tape is composed of two parts: PE base film and adhesive layer. The base film is a polyethylene film and the adhesive layer is butyl rubber. It has excellent aging resistance, sealing and insulation effects. According to its function, it can be divided into anti-corrosion belt (inner belt), protective belt (outer belt), and patch belt. Mainly used in gas, natural gas, oil field, chemical industry, construction industry, mining, tap water industry, electric power industry, communication industry, ocean, urban construction in water supply and drainage and gas transportation and other buried steel pipelines for external surface anti-corrosion.
The advantages of duct tape.
1. The thickness of the adhesive layer is uniform, and the bonding and sealing performance is good.
2. The base material and the adhesive layer have a strong bonding force, and there is no degumming phenomenon during storage or construction.
3. Good heat aging resistance and strong UV resistance.
4. High tensile strength, proper elongation at break, convenient for mechanization and manual winding.
The development of duct tape
Pipeline tape has been widely used as external anti-corrosion material for oil and gas steel pipelines since the 1960s. It has a history of more than 40 years. Due to its excellent anti-corrosion performance and convenient construction performance, it has a certain share in the pipeline anti-corrosion material system. status. And because polyethylene anticorrosive tape manufacturers continue to improve and improve the variety and quality of polyethylene tape, the application field of polyethylene anticorrosive tape continues to expand
