Polypropylene fiber

LVJIAN^® Polypropylene Fiber is a chopped fiber produced from polypropylene material through masterbatch addition, blending, spinning, drawing, and special processes including anti-static and UV resistance treatments. It is a specialized fiber for concrete and mortar that effectively controls cracks caused by shrinkage, drying shrinkage, and temperature changes in concrete and mortar. It significantly improves crack resistance and impermeability, impact and abrasion resistance, and increases concrete toughness, thereby extending service life.

● High strength and elastic modulus, beneficial to concrete's mechanical properties.

● Strong bonding with cement surface; hydrophilic treatment facilitates cement paste adhesion and improves strength.

● Excellent dispersibility, no agglomeration, effectively ensuring crack resistance performance.

● Chemically stable fiber with strong acid and alkali resistance.

1 Concrete Construction 

Reduces concrete cracks, enhances impermeability and toughness, thereby extending building service life. Particularly effective as a crack-resistant and impermeable material in concrete corrosion pools, basement projects, roofing, water storage tanks, and external wall plastering; increases fracture resistance in precast concrete panels, pipes, and reduces shrinkage and settlement cracks.

2 Tunnels  

Suitable for shotcrete on walls and ceilings in tunnels, mines, subways, and civil defense projects. Concrete rebound and fallout is reduced to no more than 4-5%.

3 Swimming Pools  

Suitable for dams, water storage tanks, canals, and swimming pools. Reduces cracking, lowers permeability, and enhances corrosion resistance.

4 Overpasses & Bridges 

Suitable for docks, highways, bridges, street concrete pavements, airports, and other applications requiring high fatigue resistance, impact resistance, and durability.
