Anticorrosive polypropylene fiber tape is a new kind of pollution-free and nondestructive anticorrosive product, representing the top level of cold-wrapping tape both at home and abroad and called “anticorrosive champion”. It can be widely used in such anticorrosive constructions as water supply, steel pipelines for conveying oil, natural gas and coal gas or underground tank outer anticorrosion or rehabilitation work in oil, natural gas, chemical engineering and municipal constructions. It is the appointed product replacing asphalt glass cloth and epoxy coal tar by the National Construction Department and Environmental Protection General Bureau. The product is characterized by its easy construction, shock resistance, aging resistance, elongation resistance, ultra-violet light resistance and high bond strength.
　 The basis material of the product is the unique modified polypropylene knitted fabrics, adopting modified butyl rubber asphalt as anticorrosive rubber. Its fabric structure can effectively resist the creep fracture due to the soil stress. Aging test shows that it can endure 50 years of corrosion, The product according with the US standards ANSI/AWWAC209-00 and NACEMR0274-95 makes it the best tape in cold antisepsis pipe construc-tion.the index of which overpasses that of the SY/T0414-98 Standard. It is the best and the most economic choice
