The product totally has three parts consisting of butyl rubber bituminous compound adhesive layer, PP woven fabric cloth backing and anti adhesive release liner treated with silicone. It is often used after the liquid adhesive by hand or with a wrapping machine. The product can be cold applied for both metallic pipeline corrosion protection and waterproofing works against outdoor bad weather.

For waterproofing works, the polypropylene mesh membrane tape has the merits of safety, cleanness, compatibility with primer, easy application and installation as well as good performance of keeping itself dry. It can be applied for basement, substructure and civil engineering works such as flat deck, plaza, bridge, vehicular traffic structure or parking deck overlaid with an asphalt concrete wearing course. The product can protect the wall, floor, roof, corner, basement, etc. from attack by bad weather, rain, acid and alkaline salt.

As to the protection for pipelines, the PP modified mesh membrane tape is widely applied in the areas of petroleum, natural gas, chemical industry and urban construction for outside anti corrosion and repair of the steel underground storage tanks and steel pipes used for water drainage and the transportation of oil and gas. The product is excellent in adhesion to pipe. Its flexibility allows for extra protection for vulnerable areas. Compatible with common pipe coatings, the PP mesh membrane tape is resistant to cathodic disbondment. It has good conformability and consistent uniform thickness.

Due to the fiber structure, the polypropylene mesh membrane tape can resist to the creep failure caused by soil stress effectively. It is showed through the ageing test that the corrosion resistance life of the product can be up to 50 years. Meanwhile, all the inspected indicators are higher than the requirements of SY/T0414-98 standard largely. The polypropylene anticorrosion tape meets the American standards of ANSI/AWWAC209-00 and NACEMR 0274-95 fully. It is the most economical and preferable choice for pipeline anticorrosion construction.

As an experienced polypropylene mesh membrane tape manufacturer and supplier in China, we also provide butyl tape, aluminum faced flashing sealing tape, heat shrink sleeves, and anticorrosion primer, among others.
