Taking polyethylene as the basic material, the PE duct protective tape is made of rubber pressure-sensitive adhesive. It is suitable for corrosion of the underground pipeline as petroleum, gas, etc.
Polyethylene tape could be divided into Anti-corrosion adhesive tape, protective adhesive tape according to usage.
