Ultra-Fine Polypropylene Fiber for Concrete | PIONEER®
Ultra-Fine Polypropylene Fibers with Low Dosage and High Performance
Achieve superior crack resistance, improved durability, and smoother finishing in concrete and mortar with PIONEER® ultra-fine polypropylene fibers. Designed for high-dispersion performance at low dosage, these micro PP fibers deliver exceptional crack control for both new construction and repair applications.
What Is PIONEER® HPM® UF PP Ultra-Fine Fiber?
PIONEER® HPM® UF PP is a high-performance ultra-fine polypropylene fiber engineered for concrete and mortar reinforcement. Manufactured from 100% virgin polypropylene, these micro monofilament fibers (≈18 μm diameter) provide an extremely high fiber count per cubic meter, forming a dense 3D network that:
-
Minimizes plastic shrinkage cracking
-
Enhances concrete durability
-
Maintains excellent workability and smooth finishing
-
Integrates seamlessly in plaster, renders, repair mortars, and industrial floors
Ideal for precast elements, overlays, SCC (self-compacting concrete), industrial slabs, pavements, and dry-mix mortars.

How Ultra-Fine Polypropylene Fibers Improve Concrete Performance
Ultra-fine PP fibers disperse uniformly throughout concrete and mortar, forming a high-density micro reinforcement network that significantly enhances performance:
-
Plastic Shrinkage Crack Control
The micro-scale diameter allows fibers to arrest early-age cracks more efficiently than standard PP fibers.
-
Smooth Surface Finishing
Their ultra-thin profile ensures no protrusion, making them ideal for visible surfaces, overlays, and industrial floors.
-
Enhanced Durability
Improves resistance to permeability, freeze–thaw cycles, and micro-cracking.
-
Ideal for Dry-Mix Applications
The small fiber size ensures excellent flowability in premixed products and bagged mortars.
