PP Fiber

Product Specification

Feature

Polypropylene fiber is a high-performance concrete reinforcement material that forms a three-dimensional random network within the concrete matrix, fundamentally addressing long-standing industry pain points such as low tensile strength, susceptibility to cracking, and inadequate durability. Its key selling points include: Excellent crack resistance – effectively inhibits micro-cracks caused by plastic shrinkage, drying shrinkage, and temperature variations, reducing early-stage cracking by over 30%; Superior mechanical properties – tensile strength ≥560MPa, elastic modulus ≥3500MPa, with a density of only 0.91 g/cm³, combining high strength with light weight; Strong chemical resistance – withstands strong acids and alkalis, non-absorbent, suitable for harsh environments; Enhanced durability – improves impermeability by approximately 37%, while enhancing freeze-thaw resistance and impact resistance, extending structural service life by over 15%; Mature technology and cost-effectiveness – surface hydrophilic modification ensures uniform dispersion and strong bonding within concrete, widely used in high-speed rail, bridges, nuclear power plants, tunnels, hydraulic engineering, and other major national infrastructure projects.
