Embossed grey PP fibers Material Composition:

  • Primary Material : 100% virgin polypropylene copolymer (no recycled content).

  • Surface Treatment : Proprietary embossing technology for superior bonding with concrete matrices.

  • Color : Grey (UV-stabilized for outdoor applications).


Key Features & Advantages:

FEATURE
TECHNICAL BENEFIT
PERFORMANCE DATA
Embossed Surface
Enhances fiber-concrete adhesion, reducing slip and improving load transfer.
+35% bond strengthvs. smooth fibers (ASTM C1399).
Shrinkage & Crack Control
Reduces plastic and drying shrinkage cracks by 60–80%in slabs-on-grade.
Crack width <0.1 mm at4 kg/m³ dosage(EN 14889-1).
Corrosion Resistance
Immune to chloride, sulfate, and alkali attacks—ideal for marine/industrial environments.
Outperforms steel fibers insalt spray tests(ASTM B117).
Dosage Efficiency
3–10 kg/m³achieves comparable performance to25–40 kg/m³ steel fibers.
70% lower material costwhile meeting ASTM C1609 toughness requirements.
Workability & Safety
Non-conductive, lightweight (0.91 g/cm³), and eliminates steel fiber handling hazards.
50% faster mixingvs. steel fibers (no balling or segregation).

Note : PP fibers are optimal for 90% of industrial floors , while steel fibers are reserved for ultra-high-impact zones (e.g., airport       

              runways).


Recommended Dosage:

  • Slabs-on-Grade : 3–6 kg/m³ for crack control.

  • Precast Concrete : 4–8 kg/m³ to reduce handling cracks.

  • Marine Structures : 5–10 kg/m³ for corrosion-free durability.

  • Shotcrete : 6–10 kg/m³ to minimize rebound and cracking.


Why Choose Embossed PP Fibers?

1.Cost-Effective : 70% savings vs. steel fibers.

2.Durability : No rust, even in wet environments.

3.Ease of Use : Uniform dispersion without balling.

Ideal for : Warehouses, parking garages, tunnels, and decorative concrete.

Typical Application

Shotcrete, and engineering industries, concrete project,like:

◆Slab on Grade and elevated construction (distribution centers, warehouses, etc.)

◆Thin walled precast (septic tanks, vaults, walls, etc.)

◆Shotcrete for tunnel linings, pool construction and slope stabilization

◆Pavements and white-toppings

How should the fibre be used

The fibers are wrapped with water-soluble film and uniquely packaged in water soluble paper

boxes.Just throw the whole boxes of fibers into the concrete mixture, the boxes and film will dissolve

within seconds, leaving the fibers to disperse evenly throughout the mixture.
