Polypropylene microfiber is a kind of synthetic fiber, which is made by raw polypropylene ,after hot melting, drawing , and then cut into different length. According to the size , polypropylene fiber has different uses. One of them is used as a secondary reinforced material for concrete products. Because of its rich raw materials, light texture, low price, acid and alkali resistance, it is favored by concrete engineering, and can be used in any concrete projects, precast, thermal insulation mortar project, etc.
