Polyethylene anticorrosion adhesive tape 660, also known as 660 anti-corrosion tape, asphalt corrosion tape, anticorrosive tape polyethylene, PE anti-corrosion tape, adhesive tape wrapped around the cold, because of his mending, preservation and protection as one of the anti-corrosion, also known as PE 660 one band, and some manufacturers also known as: PipeCoat polyethylene anticorrosion tape, my tape in the traditional polyethylene corrosion developed on the basis of a new type of anti-corrosion tape wrapped around the cold masterpiece. The substrate for the high and low density polyethylene membrane synthesis, high-viscosity thermoplastic adhesive self-adhesive anti-corrosion adhesive butyl modified, supplemented by a layer of isolated anti-sticking film composition. Can be widely used in petroleum, natural gas, chemicals, urban construction, water supply and drainage and oil and gas, gas transmission pipeline steel, and steel underground storage tank outside the preservation and restoration projects. Is a new non-polluting, non-hazardous environment-friendly anti-corrosion material, compared with the traditional anti-corrosion adhesive tape has the following advantages: 
 1, adhesive strength and can achieve self-fusion, water, gas permeability, good seal. 
 2, electric insulation, anti aging stability and excellent resistance to ultraviolet radiation and strong. 
 3, with the ability to resist soil stress fracture, strong impact. 
 4, the tape winding layer can be realized SY/T0414-2007 standard or enhanced level of ordinary corrosion. Changed the traditional tape to be multi-layer winding, reducing the corrosion process of human factors on job quality and the impact of corrosion and reduce the construction costs. 
 5, the construction is simple, fast, no curing time, hand, machine operations, can shorten the construction period. 
 Polyethylene anticorrosion tape 660 identified by the national professional testing, the indicators SY/T0414-2007 standards much higher than in full compliance with the United States ANSI/AWWAC209-00 and NACEMR0274-95 index, is the most anti-corrosion tape wrapped around the cold economy most environmentally friendly products, with high application value.
