Polyethylene adhesive tape is a coil-shaped anti-corrosion protection material used for oil and natural gas transmission, chemical industry, water supply and drainage and gas transportation in urban construction and other buried steel pipelines. Polyethylene adhesive tape is made of a film made of polyethylene resin through extrusion and calendering as the base material, and a solvent-free butyl rubber adhesive with good sealing properties, which is made through a thermal compounding process. According to SY/T0414-2017, it is called polyolefin adhesive tape. According to the thickness of the adhesive and the base material, it is composed of thick plastic polyethylene adhesive tape and thin plastic polyethylene adhesive tape. The thick glue type adhesive is greater than or equal to 70%, and the thin glue type is only about 30%. The thick rubber type has a release film, while the thin rubber type does not.
