Polypropylene mesh fiber

Polypropylene mesh fiber, a bundle of fibers interlaced into a net shape, is made from polypropylene granules through special processing and treatment. When added to concrete mix and blended, the fibers or mesh structure fully expands, forming a random support system within the concrete. It effectively controls the early plastic shrinkage and settlement cracks in concrete and cement mortar. It significantly enhances the concrete's impermeability, resistance to fragmentation and impact, and improves its toughness and wear resistance, thereby greatly extending the service life of buildings and substantially reducing maintenance costs.

Polypropylene mesh fibers are a bundle of fibers interlaced into a mesh, produced through special processing and treatment of polypropylene resin. They possess strong adhesion with the matrix of cement concrete. When added to the concrete matrix and mixed, they automatically expand due to the impact of cement, sand, and aggregates. They become individual filaments or multi-directionally entangled fibers, forming a chaotic support system within the concrete. They effectively control the early plastic shrinkage and settlement cracks of concrete and cement mortar. This significantly enhances the concrete's impermeability, resistance to fragmentation and impact, and its toughness and wear resistance, thereby greatly extending the service life of buildings and significantly reducing maintenance costs.
