Macro structural Synthetic polymer PP Polypropylene hybrid fiber for concrete

Polypropylene Hybrid Fiber – Introduction

Polypropylene Hybrid Fiber is a high-performance macro-synthetic fiber manufactured from virgin polymers.

It combines twisted fiber and mesh fiber to deliver superior structural reinforcement.Engineered for durability and versatility, this fiber           

 exhibits high tensile  strength, excellent dispersion, outstanding corrosion resistance .


Polypropylene Hybrid Fiber Key Features & Benefits

Superior Dispersion – Ensures uniform distribution within concrete/mortar matrices.

High Tensile & Shear Strength – Enhances load-bearing capacity and structural resilience.

Crack Resistance – Reduces micro/macro-cracking in hardened concrete.

Fatigue & Corrosion Resistance – Prolongs service life in harsh environments.

Exceptional Toughness – Improves impact resistance and deformation tolerance.

This fiber is an optimal solution for modern construction challenges, balancing cost-efficiency with long-term performance.

Polypropylene Hybrid Fiber Primary Applications

◆ Infrastructure:

     Roads, bridges, tunnels, and underground waterproofing  systems.

◆ Construction:

     Industrial & civil structures (roofing, walls, basements,   swimming pools).

◆ Durability Solutions:

     Crack prevention, fatigue resistance, and long-term structural integrity.


Polypropylene Hybrid Fiber in Concrete: Performance & Applications

Key Performance Benefits

  1. Crack Control & Structural Reinforcement

    • Reduces Plastic shrinkage cracks  by up to 70-90% (ASTM C157).

    • Controls macrocracks (width <0.1 mm) and macrocracks in hardened concrete.

  2. Improved Durability

    • Freeze-thaw resistance:Increases cycles to failure by 30-50% (ASTM C666).

    • Abrasion resistance:Reduces surface wear by 20-40% (ASTM C944).

  3. Enhanced Toughness

    • Impact resistance :Improves by 3-5x vs. plain concrete (ACI 544 testing).

    • Post-crack behavior:Maintains load-bearing capacity after cracking.

  4. Workability & Homogeneity

    • Reduces bleeding/segregation by 40-60% , ensuring uniform mix consistency.


Recommended Applications
