Therefore, it is mainly used for the function of pipeline corrosion.

Duct tape:

Duct tape is based on the thermal composite of polyethylene and gauze fibers. It has a strong peeling force, tensile resistance, oil resistance, aging resistance, temperature resistance, waterproof, corrosion resistance, so it is also used in pipeline waterproof.
