Macro Synthetic Fiber

FedFiber®FDM500 is one macro polymer fiber, used for structural concrete reinforcement. As macro structural synthetic fiber ,it has waved shape ,which make the fiber can bond with the concrete together tightly ,and improve the cracking resistance of concrete .FDM500 made by raw polypropylene blend with polyethylene,so it has perfect alkali resistance ,corrosion resistance,durability. Some times , the fiber can replace the steel fiber or steel bar completely in special concrete projects, like concrete floor, slab,airway etc.
