Polypropylene fiber (PP fiber) is a versatile synthetic fiber manufactured from 100% polypropylene resin via melt-spinning technology. As a lightweight, durable, and cost-effective solution, it has become an essential material across global construction, textile, and industrial sectors. With superior physical and chemical properties, our PP fiber is engineered to enhance material durability, reduce costs, and deliver reliable performance in diverse applications.
Key Advantages of Our Polypropylene Fiber
Exceptional Lightweight & High StrengthWith a density of only 0.91 g/cm³—the lowest among common chemical fibers—PP fiber is 30% lighter than polyester and 40% lighter than viscose fiber. It boasts high tensile strength (≥460 MPa) and stable wet/dry strength, ensuring reliable reinforcement without adding extra weight to the substrate.
Unmatched Chemical Corrosion ResistancePP fiber exhibits excellent resistance to acids, alkalis, salts, and organic solvents. It never rusts like steel fiber, making it ideal for harsh environments such as marine structures, saline-alkali soils, and industrial facilities. Its chemical stability ensures long-term performance consistent with the lifespan of concrete matrices.
Superior Anti-Crack & Reinforcement PerformanceWith a fine diameter (10–50 μm) and large specific surface area, PP fiber forms a uniform three-dimensional network in concrete/mortar. It effectively bridges micro-cracks, inhibiting plastic shrinkage and temperature cracks, and improves anti-permeability, impact resistance, and freeze-thaw durability by 30–50%.
Excellent Dispersibility & Easy ApplicationOur PP fiber undergoes special surface modification (hydrophilic/anti-static treatment) to prevent agglomeration during mixing. It disperses evenly with ordinary mixing equipment, requiring no specialized machinery—suitable for all pouring processes and construction scales.
Eco-Friendly & Cost-EffectiveProduced with eco-friendly processes and recyclable materials, PP fiber aligns with global green construction standards. It requires a low dosage (0.6–1.2 kg/m³ in concrete) and is priced significantly lower than steel or carbon fiber, delivering high performance at a competitive cost.
