Polypropylene tape is a new type of non-polluting, non-hazardous and environmentally friendly anti-corrosion material, representing the highest level of international and domestic cold-wound anti-corrosion tapes, and has the reputation of “the crown of anti-corrosion”. The base material is a unique modified polypropylene woven fiber cloth, and butyl rubber modified asphalt is used as the anti-corrosion adhesive layer. The base material is a fiber structure that can effectively resist creep damage caused by soil stress. It is tested by aging tests It has been proved that its corrosion resistance life can reach more than 50 years. It can be widely used in oil, natural gas, chemical industry, water supply and drainage in urban construction, oil and gas, gas transmission steel pipelines and external anticorrosion and repair projects of steel buried storage tanks. It is the recommended product designated by the Ministry of Construction and the State Environmental Protection Administration to replace “asphalt glass cloth” and “epoxy coal tar pitch”. It has the characteristics of simple construction, impact resistance, aging resistance, tensile resistance, ultraviolet radiation resistance, and high bonding strength. It is the best choice among pipeline cold anti-corrosion construction tapes, and also the most economical choice for anti-corrosion.
