Ultra-Fine Polypropylene Fiber for Concrete | PIONEER®
Ultra-Fine Polypropylene Fibers with Low Dosage and High Performance
Achieve superior crack control and durability in your concrete projects with PIONEER® ultra-fine polypropylene fibers at lower dosage
What Is PIONEER® HPM® UF PP Ultra-Fine Fiber?
PIONEER® HPM® UF PP is a high-performance ultra-fine polypropylene fiber designed for fiber-reinforced concrete and mortar applications. Using 100% virgin resin, these micro monofilament fibers have a diameter as small as 18 microns, delivering the highest fiber count per cubic meter for exceptional crack control while maintaining smooth finishes and workability. Ideal for infrastructure, industrial floors, precast elements, and repair mortars, these fibers form a dense 3D network that minimizes plastic shrinkage cracking and extends service life.

How Polyacrylonitrile (PAN) Fibers Enhance Asphalt Pavements
Discover how ultra-fine pp fiber reinforcement transforms concrete and mortar by reducing cracking and increasing durability.
These ultra-fine fibers disperse evenly throughout concrete and mortar, creating a high-density reinforcement network that controls plastic shrinkage cracking while maintaining the workability and smooth finish of surfaces. The small fiber diameter allows seamless plastering and troweling, making them ideal for overlays, industrial floors, pavements, repair mortars, and dry-mix products where surface quality matters.
