PAN Fiber for Concrete
Polyacrylonitrile Micro Synthetic Fiber for Concrete and Cementitious Systems
HPM® PAN is a polyacrylonitrile (PAN) monofilament micro synthetic fiber for concrete applications where fine-fiber distribution, material properties and crack-control requirements are important selection criteria.
It can be evaluated for high-performance concrete, precast elements, floors, shotcrete, mortar and other cementitious systems according to product dosage, fiber dimensions and project requirements.
What Is HPM® PAN Fiber?
HPM® PAN is a polyacrylonitrile micro synthetic fiber designed for concrete and cementitious materials. The product uses fine monofilament fibers that are distributed throughout the mix to provide micro-scale reinforcement within the cementitious matrix.

How HPM® PAN Fiber Works in Concrete
HPM® PAN uses fine monofilament fibers distributed throughout the cementitious matrix. The high fiber count created by the small fiber diameter allows microfibers to intersect developing cracks at multiple locations when adequate dispersion is achieved.
Micro-Scale Fiber Distribution
The fine PAN fibers are intended to provide distributed micro-reinforcement within the concrete or mortar matrix. Fiber distribution depends on dosage, fiber length, batching sequence, concrete workability and mixing conditions.
Crack-Control Role
Fibers crossing developing cracks can help limit crack opening at the micro scale. The actual crack-control performance depends on the concrete mix, fiber dosage, curing conditions and the applicable test method.
Product-Specific Performance
Any quantified improvement in shrinkage cracking, toughness, durability or other concrete properties should be confirmed using HPM® PAN product-specific test data.

Key Features of HPM® PAN
Fine Monofilament Fiber
Uses a fine polyacrylonitrile monofilament format for distributed micro-scale reinforcement in concrete and mortar.
Multiple Fiber Lengths
Available fiber lengths can be matched to different cementitious applications according to the current product specification.
Micro-Crack Bridging
Fine fibers can intersect developing cracks within the cementitious matrix when adequately dispersed.
High Fiber Count
The small fiber diameter provides a high number of individual fibers per unit mass compared with larger-diameter reinforcement fibers.
Product-Specific Dosage
Dosage should be selected according to the application, fiber length, concrete or mortar mix and required performance.
Broad Cementitious Application Range
HPM® PAN can be evaluated for concrete, mortar, precast, floors, overlays, shotcrete and selected high-performance cementitious systems.
Recommended Applications
High-Performance Concrete
HPM® PAN can be evaluated for high-performance concrete where fine-fiber reinforcement, matrix compatibility and project-specific crack-control requirements are important selection criteria.
Precast Concrete
PAN fiber may be evaluated in precast elements according to fiber length, concrete mix, production process, surface-finish requirements and required performance.
Industrial Floors and Slabs
HPM® PAN can be evaluated for slabs, floors and pavement-related applications where micro-scale crack-control objectives are part of the concrete design.
Mortar, Repair and Overlays
Shorter PAN fiber grades may be evaluated for mortar, repair materials and thin overlays where fiber length, dispersion and finish are compatible with the matrix.
Shotcrete and Underground Works
HPM® PAN may be considered for selected shotcrete applications where fiber distribution, pumping or placement requirements and project performance criteria have been confirmed.
Water-Retaining and Infrastructure Concrete
The product may be evaluated in tanks, basements, tunnels and other concrete structures where project-specific crack-control or durability requirements justify microfiber reinforcement.
Dosage and Mixing Guidelines
HPM® PAN dosage should be selected according to fiber length, concrete or mortar application, required performance, mix design and current product technical data.
Mixing procedures should provide sufficient time and distribution to incorporate the selected PAN fiber grade consistently throughout the cementitious matrix.

PAN and polypropylene are different polymer fiber materials with different physical properties, available dimensions and product formulations. Select between them according to the concrete application, required performance, dosage and product-specific test data.
Reinforcement Design Considerations
HPM® PAN is a micro synthetic fiber product and should not be treated as a universal replacement for structural reinforcement.
Where a project considers reduction or substitution of welded wire reinforcement or other conventional reinforcement, the decision should be based on structural design, applicable test data and project-specific approval rather than PAN fiber dosage alone.
Applicable Standards and Technical References
Applicable standards depend on the HPM® PAN product grade, intended application and destination market. Review the latest technical data and conformity documents before specifying the product.
Product documentation may reference standards for synthetic fibers and fiber-reinforced concrete. Confirm the applicable classification, test method and current edition in the controlled product documentation.
Packaging and Supply
HPM® PAN is available for project, precast, ready-mix and distributor supply. Packaging and available fiber lengths may vary according to product grade, project requirements, destination and order volume.

FAQ
HPM® PAN is a polyacrylonitrile monofilament micro synthetic fiber designed for concrete and other cementitious materials. It is used where fine distributed fiber reinforcement and project-specific crack-control requirements are being evaluated.
PAN fibers can be distributed through the cementitious matrix to provide micro-scale crack bridging. Their suitability depends on fiber dimensions, dosage, concrete or mortar mix and the performance required by the project.
Final dosage should follow the current HPM® PAN Technical Data Sheet and should be selected according to fiber length, application, concrete or mortar mix and required performance.
PAN and polypropylene are different polymer fiber materials with different physical properties and product formulations. Select between them using product-specific dimensions, dosage, technical data and project performance requirements rather than assuming one material is universally better.
HPM® PAN is a micro synthetic fiber and should not be treated as a universal replacement for structural steel reinforcement. Any reduction or substitution of conventional reinforcement should be supported by project design, testing and applicable approval.
