Polypropylene PP Fiber for Concrete Reinforcement
Polypropylene (PP) Fiber is a high-performance synthetic fiber designed to enhance the durability and mechanical performance of concrete and mortar systems. At Hebei InnoNew Material Technology Co., Ltd., our PP fiber is engineered to effectively control plastic shrinkage cracking, improve impact resistance, and increase long-term structural stability. Widely used in ready-mix concrete, dry mortar, shotcrete, and precast applications, PP fiber serves as an efficient and cost-effective alternative to traditional steel reinforcement in specific applications.

FAQ:
1. What is polypropylene fiber used for in concrete?
PP fiber is used to control cracking, improve durability, and enhance the structural integrity of concrete.
2. Is PP fiber better than steel fiber?
PP fiber is ideal for crack control and lightweight reinforcement, while steel fiber is used for structural load-bearing applications.
3. How much PP fiber should be added to concrete?
Typically 0.6–1.8 kg per cubic meter depending on application.
4. Can PP fiber prevent cracks completely?
It significantly reduces plastic shrinkage cracks but does not completely eliminate all types of cracking.
