PP Staple Fiber is a kind of fiber. Polypropylene staple fiber can
improve the crack resistance, impermeability, erosion resistance,frost resistance, anti-explosive ability of mortar / concrete and
improve the workability of concrete. Tens of millions of fibers are evenly distributed in the mortar /
concrete, which plays a very good role in micro-reinforcement. This maintains the integrity of the
structure and prevents the structure from being scattered into many fragments when it is damaged impact, which prevents Corrosion of reinforcing steel in the structure can greatly extend the service life of the project and reduce the maintenance cost of the project .
