Product Description Polypropylene short fiber Polypropylene short fiber is a synthetic fiber. Polypropylene short fiber effectively enhances the crack resistance, water resistance, abrasion resistance, and freeze-thaw resistance of mortar/concrete while improving concrete workability. Polypropylene fiber(synthetic fibre) is a high-strength fiber produced by special process using polypropylene as raw material. The product can be made into a mesh or a monofilament. When the fibers are added into concrete or mortar, the horizontal structure of the fibers may be destroyed during the agitation due to friction, and the fiber monofilament or the network structure will be completely stretched, thereby reinforcing the concrete and the mortar, effectively control the cracks caused by solid shrinkage, drying shrinkage, temperature change and other factors, prevent and inhibit the formation and development of cracks, and greatly improve the crack resistance, impermeability, seismic and impact resistance of mortar and concrete.SpecificationsStandardSpecificationsStandardLength (mm)3,6,9,12 Tensile Strength MPa≥400Initial Modulus(GPa)≥3.5Crack Elongation %15~35Melting point oCAbout 165Ignition point oCAbout 580Resistance to AcidStrongOperational SafetyNon-toix or irritantResistance to AlkaliStrongThermal ConductivityVery lowCold resistanceGoodMagnetismNonePolypropylene fiber is suitable for dry powder mortar products like thermal insulation mortar, anti-cracking mortar, interior and exterior wall putty, waterproof mortar, plasterboard and lightweight concrete slab putty, cement-gypsum-based plastering mortar, etc. It is used in cement mortar or concrete applications, such as roads and bridges, dams, highways, culverts, subway projects, etc.Polypropylene fiber possess outstanding physical and chemical properties, forming the foundation for their application in mortar. High tensile strength enables these fiber to withstand significant external stress without breaking. This characteristic ensures the formation of a robust network structure within the mortar, effectively preventing the propagation of fine cracks.Excellent dispersibility is a key advantage of polypropylene fiber. When added to mortar, they distribute uniformly throughout the mixture without local agglomeration. This even distribution ensures the fiber reinforce the entire mortar matrix, enhancing overall crack resistance and toughness.Furthermore, crack resistance is a particularly critical aspect of mortar performance. Due to polypropylene fiber' high tensile properties and excellent dispersibility, they effectively mitigate micro-cracks caused by drying shrinkage and temperature fluctuations, thereby extending the service life of the mortar.
