Shanghai Mac Corporation is a leading Polypropylene fiber manufacturer and supplier.

Polypropylene fiber is a synthetic fiber made from 100% polypropylene via melt-spinning. Its core value lies in acting as secondary reinforcement that disperses uniformly in concrete or mortar, effectively controlling micro-cracks caused by plastic shrinkage and temperature variation. This enhances the material's crack resistance, impact resistance, and durability. While it does not replace structural steel reinforcement, it physically toughens cement-based materials, significantly improving impermeability and integrity. Polypropylene fiber is a key additive in modern high-performance concrete, mortar, and various building materials for crack control, seepage prevention, and toughness enhancement.
