Polypropylene fiber is a high-strength fiber produced from polypropylene as its raw material through a special manufacturing process. This product can be made into a net-like structure or individual filaments. When these fibers are added to concrete or mortar during the mixing process, the horizontal structure of the fibers is disrupted due to friction, causing the fibers’ individual filaments or net-like structure to be fully stretched. This enhances the concrete and mortar, effectively controlling and preventing cracks caused by factors such as solid shrinkage, drying shrinkage, temperature fluctuations, and more. It serves to prevent and inhibit the formation and development of cracks, significantly improving the crack resistance, water impermeability, seismic resistance, and impact resistance of mortar and concrete.
