Synthetic macro fiber for concrete low price Polypropylene macro fiber high strength PP macro fiber

 Synthetic macro fiber for concrete low price Polypropylene macro fiber high strength PP macro fiber Polypropylene steel like fiber is an iron belt product that fills the gap between steel fiber and polypropylene fiber. Its performance is between the two. It is a monofilament fiber like shear steel fiber. The surface of the fiber is rough and uneven. It is a new type of reinforcement and toughening material. When the content of fiber is high, the fiber has a significant effect on the early crack resistance of concrete, It can replace steel fiber or steel mesh to increase the toughness of concrete and improve the ability to resist temperature stress or burst.
