HPM UF PP Ultra-Fine Polypropylene Fiber
Ultra-Fine PP Microfiber for Concrete and Mortar
HPM UF PP is an ultra-fine monofilament polypropylene fiber designed for concrete, mortar and other cementitious applications where fine fiber diameter, high fiber count, dispersion and surface-finish requirements are important.
What Is HPM UF PP Ultra-Fine Fiber?
HPM UF PP is an ultra-fine monofilament polypropylene microfiber manufactured from polypropylene for use in concrete, mortar and related cementitious materials. Its fine diameter increases the number of fibers distributed through the mix compared with coarser PP fibers, making it suitable for applications where crack-control, dispersion and surface-finish requirements are important.
Typical applications include precast concrete, overlays, industrial floors, SCC, repair mortars, plaster, render and dry-mix mortar, subject to the current product TDS and project requirements.

How Ultra-Fine Polypropylene Fibers Work
The fine diameter of HPM UF PP allows a high number of individual fibers to disperse through concrete or mortar. This dense fiber distribution can help interrupt early microcrack development and support cohesion, while the small fiber size may also be useful in applications where surface finish and fine dispersion are important.
Final performance depends on fiber length, dosage, mix design, application and project conditions.

Key Benefits
Ultra-Fine Fiber Geometry
Fine fiber diameter supports a high number of individual fibers within the mix.
High Fiber Distribution
Fine monofilaments can provide dense distributed micro-reinforcement throughout concrete or mortar.
Fine Surface Finish
Small fiber dimensions can be useful where visible fiber protrusion and finish are important considerations.
Chemical Resistance
Polypropylene offers resistance to many alkaline and chemical environments, subject to product documentation.
Easy Integration
Fibers can be incorporated into concrete or mortar using the recommended batching and mixing procedure.
Recommended Applications
Precast Concrete
For selected precast applications where fine fiber distribution and surface finish are important.
Mortar, Plaster and Render
Suitable for selected cementitious mixes requiring fine fiber dispersion and crack-control support.
Dry-Mix and Repair Mortars
Fine fiber dimensions can be useful in bagged mortar and repair formulations where dispersion is a key requirement.
Floors, Overlays and Toppings
For selected thin-section or finish-sensitive applications where early-age crack control is required.
SCC and Fine Concrete Systems
May be evaluated where fiber dispersion and flowability are important, subject to mix compatibility and current technical guidance.

FAQ
HPM UF PP uses a finer fiber diameter, providing a higher number of individual fibers within the mix compared with coarser PP microfiber products.
It is designed for early-age crack-control applications. Final performance depends on dosage, concrete or mortar mix, environmental conditions and project requirements.
HPM UF PP should not be treated as a universal replacement for structural reinforcement. Any substitution should be supported by project design and required performance.
The current product page lists 0.45 kg/m³ as a typical dosage. Confirm the final dosage in the current TDS and according to project requirements.
It may be suitable for selected SCC and precast applications where fine fiber dispersion and finish are important. Compatibility should be confirmed with the mix and current technical guidance.
