Your Trusted Synthetic Microfiber Supplier for Concrete Reinforcement
As a leading fiber manufacturer in China, TenaBrix producing fibers with exceptional quality and reliability. These fibers disperse evenly in concrete or mortar, significantly improving durability and performance.
Whether for industrial floors, precast elements, repair mortars or general concrete reinforcement, TenaBrix provides not only this microfiber but also a full range of fiber solutions to meet diverse construction needs.
Main Applications & Key Advantages
With outstanding performance and cost-effectiveness, Polypropylene Fiber is widely recognized as a reliable solution for concrete reinforcement and mortar crack control in construction industries worldwide.
Shotcrete: tunnel linings, slope protection, underground construction
PP Fiber for Shotcrete is an effective reinforcement material that enhances the performance and durability of sprayed concrete.
- Higher Mechanical Strength: significantly improves the tensile strength, shear strength, and fatigue resistance of shotcrete.
- Enhanced Toughness & Durability: increases concrete toughness, better resists deformation, and extends the overall service life of structures.
- Improved Workability: optimizes the construction performance of shotcrete, ensuring better adhesion and reduced rebound during spraying.
Precast Elements: piles, panels, blocks
Polypropylene (PP) Fiber is widely used in precast concrete products to enhance crack resistance, strength, and durability.
- Crack Control: effectively inhibits and reduces shrinkage cracks in concrete during both the plastic stage and the hardening stage.
- Higher Mechanical Strength: significantly improves the tensile strength, flexural strength, shear strength, and fatigue resistance of precast concrete.
- Improved Frost Resistance: enhances the ability of concrete to withstand freeze-thaw cycles, extending service life in harsh environments.
Mortar Products: cement plaster mortar, cement render, repair mortar, wall putty
Polypropylene (PP) Fiber is an excellent additive for renders, plasters, and mortar, providing enhanced strength, durability, and crack resistance.
- Improved Anti-Seepage Performance: effectively reduces permeability and enhances waterproofing properties of renders, plasters, and mortar.
- Crack Resistance: significantly minimizes shrinkage cracks and improves overall durability.
- Enhanced Strength: increases compressive and tensile strength, especially in lightweight plaster applications.
Concrete Projects: industrial floors, highways, bridges, tunnels, airport runways, hydraulic structures
Polypropylene (PP) Fiber is an ideal reinforcement material for large-scale concrete projects, enhancing durability, toughness, and crack resistance. It is widely used in industrial floors, highways, bridges, tunnels, airport runways, and hydraulic structures.
- Crack Resistance: effectively reduces shrinkage and temperature cracks.
- Enhanced Strength & Durability: improves tensile, flexural, and fatigue performance.
- Long-Term Reliability: extends service life of concrete structures in demanding applications.
Best-Selling Lengths & Applications of PP Fiber
At Tenabrix, our PP fiber are available in a variety of lengths to meet different performance requirements in concrete reinforcement.
By choosing the right length, you can optimize crack resistance, toughness, and durability across a wide range of concrete projects.
6mm Polypropylene Fiber
6mm PP fibers are commonly used in thin-layer mortars to improve crack resistance and prevent microcracks caused by temperature fluctuations, shrinkage, and other stress factors. Their shorter length allows for uniform dispersion within the mortar matrix, effectively controlling crack propagation.
12mm Polypropylene Fiber
12mm PP fibers are designed for thicker concrete structures, especially in load-bearing areas or zones with high stress concentration. The longer fibers enhance impact resistance, flexural strength, and crack control, significantly improving the structural performance of concrete.
18mm Polypropylene Fiber
18mm PP fibers are specially designed for large-scale and heavy-duty concrete projects. With their extended length, they provide superior toughness, energy absorption, and crack bridging performance, making them ideal for structures exposed to dynamic loads and harsh environments.
Packing
