Self-Dispersing Polypropylene Fibers for Crack Control | PIONEER®
Engineered for Tangle-Free, Uniform Dispersion in Dry-Mix Mortars
What Are PIONEER® HPM® SD PP Self-Dispersing Fibers?
PIONEER® HPM® SD PP is a self-dispersing monofilament polypropylene fiber engineered for dry-mix mortar systems. With a triangular cross-section and advanced anti-static treatment, the fibers disperse instantly and evenly—eliminating clumping issues that traditional polypropylene fibers cannot avoid.
This high-dispersion, tangle-free fiber helps manufacturers achieve:
-
Consistent crack resistance
-
Enhanced micro-crack control
-
Improved durability and cohesion
-
A stable 3D reinforcement network inside mortar matrix
-
Backed by 22+ years of fiber reinforcement expertise, PIONEER® delivers reliable, cost-effective solutions for global mortar and plaster producers.

Uniform 3D fiber distribution
-
Improved plastic shrinkage crack resistance
-
Enhanced toughness & impact resistance
-
Longer service life of mortar formulations
-
Invisible appearance in thin coatings & plasters

Need Better Crack Control Than Polypropylene Fiber?
Polypropylene fiber is widely used for basic crack control in concrete, especially for plastic shrinkage. It is a practical and cost-effective solution in most standard applications.
However, for projects requiring reduced visible cracking, higher durability, and long-term performance, its effect after hardening can be limited.
Upgrade to Rimix™ NanoRebar
Rimix™ NanoRebar is an advanced micro fiber designed for more efficient crack control.
Its ultra-fine diameter creates significantly more fibers per m³, increasing the chance of stopping micro-cracks early.
With higher strength and modulus, it works in both the plastic and hardened stages, helping improve crack resistance, toughness, and overall concrete reliability — not just early shrinkage control.

Higher Efficiency, Same Cost Level
At roughly half the dosage, NanoRebar delivers more reinforcement points and stronger performance, while maintaining a comparable cost per cubic meter.
It’s a simple upgrade from polypropylene fiber — achieving better crack control without increasing total project cost.

FAQ
Self-dispersion fibers refer to specially treated concrete reinforcement fibers that can rapidly disperse and distribute uniformly throughout the concrete mix once added to the mixer. They do not form clumps or fiber balls, ensuring efficient mixing and a more consistent reinforcement effect across the entire concrete matrix.
These fibers enhance crack resistance by controlling plastic shrinkage, reduce microcrack formation, and improve toughness. Because they disperse automatically, they provide more consistent reinforcement compared to traditional fibers that may ball or agglomerate.
Yes. Self-dispersion fibers eliminate common issues like fiber balls and uneven distribution. They can be added directly into the mixer or during batching, simplifying the mixing process and reducing mixing time.
Self-dispersion fibers are ideal for ready-mix concrete, precast components, industrial flooring, shotcrete, overlays, mortar, and any projects requiring rapid batching or high dispersion consistency. They are especially useful in high-volume plants where mixing efficiency matters.
No. Properly engineered self-dispersion fibers maintain good workability and finishability. Because they disperse uniformly, they do not create fiber clumps that interfere with surface finishing, making them suitable for slabs, pavements, and architectural surfaces.
