The difference between polyethylene anticorrosive tape and polypropylene anticorrosive adhesive is as follows: 1. Polyethylene anticorrosive tape is an industrial adhesive tape for anticorrosion, which consists of polyethylene substrate and adhesive layer, and the base film is made of polyethylene diaphragm and the adhesive layer is made of butyl rubber, which has good mechanical strength and adhesive sealing performance. Mainly used in oil and natural gas transmission; The external surface anticorrosion of buried steel pipelines such as water supply and drainage and gas transportation in chemical industry and urban construction has the characteristics of convenient construction and no pollution. 2. Polypropylene anticorrosive tape is a new type of pollution-free and harmless environment-friendly anticorrosive material. Its base material is a unique modified polypropylene woven fiber cloth, and butyl asphalt rubber is used as the anticorrosive adhesive layer. It can be widely used in water supply and drainage in petroleum, natural gas, chemical industry, urban construction, external corrosion protection and repair works of steel pipelines and steel underground storage tanks for oil and gas transportation. It has the characteristics of simple construction, impact resistance, aging resistance, tensile resistance, ultraviolet radiation resistance and high bonding strength.
