PP fiber (microfiber)is a kind of synthetic fiber, which is made by hot melting, drawing and short cutting. According to the size and measures, polypropylene fiber has different uses. One of them is used as a secondary strengthening material for concrete . 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 engineering, concrete prefabricated products, thermal insulation mortar engineering, etc.
