FR Top-Grade Polyacrylonitrile (PAN) Fiber Manufacturer
Improve Concrete Durability & Crack Resistance with High-Performance PAN Fiber
Tenabrix® Polyacrylonitrile Fiber (PAN Fiber) is engineered to enhance concrete strength, reduce cracking, and improve long-term structural performance.
Ideal for bridge decks, industrial flooring, tunnels, airport pavements, and other demanding concrete applications.
Why PAN Fiber?
Concrete fails in ways you can't see — until it's too late
Micro-cracks form long before visible damage appears. By the time you notice, repair costs have already spiraled. PAN fiber reinforcement stops this cycle at the source.
Without PAN Fiber
× Micro-cracks propagate unchecked, reducing structural lifespan by 30–50%
× Steel fiber corrodes in humid or chemical environments — costly replacements
× Fatigue failure under cyclic loads (bridges, runways, industrial floors)
× Higher long-term maintenance costs erode project profitability
× Inconsistent concrete performance across temperature extremes
With PAN Fiber
√ 3D fiber network arrests micro-cracks at formation — up to 80% reduction
√ Corrosion-proof — outperforms steel fiber in wet, acidic, and marine environments
√ 2–3× improvement in fatigue life under repeated loading conditions
√ Lower lifecycle costs: fewer repairs, longer service intervals
√ Stable performance from -40°C to 200°C — one fiber, all climates

Key Benefits
Why choose Tenabrix PAN Fiber
Every feature translates to a measurable business outcome. Here’s what that means for your bottom line.
Superior Crack Control
Forms a 3D micro-reinforcement network that prevents plastic shrinkage cracks during curing — reduces early-age cracking by over 80%.
High Tensile Strength
≥ 500 MPa tensile strength improves structural integrity under heavy loads — ideal for industrial flooring and bridge decks.
100% Corrosion-Proof
Unlike steel fibers, PAN fiber never rusts. Performs reliably in marine environments, chemical plants, and high-humidity tunnels.
Custom Lengths
Available in 3, 6, 12, and 18 mm lengths. We help match the right fiber size to your application for optimal dispersion and performance.
Excellent Dispersion
Fine 14–18 μm diameter ensures uniform distribution throughout the concrete mix — no clumping, no weak spots.
Global Supply Chain
500-ton daily stock, 6 automated production lines, 7–10 day worldwide delivery. Consistent quality, batch after batch.
Where It’s Used
PAN Fibers had shown excellent performance in multiple applications
Every feature translates to a measurable business outcome. Here’s what that means for your bottom line.
Industrial Flooring
Resists heavy forklift traffic, prevents shrinkage cracks, extends maintenance-free service life.
Bridge Decks
Absorbs cyclic traffic loads and thermal stress — reduces spalling and rebar corrosion.
Tunnel Linings
Controls early-age cracking, withstands high humidity, and provides long-term structural stability.
Airport Runways
Enhances fatigue resistance under repeated aircraft loading — fewer closures, safer operations.

Common Questions
Frequently Asked Questions
What is the minimum order quantity (MOQ)?
We don’t impose a minimum. Whether it’s just a few pieces or a full production order, we’re ready to support you with the quantity that fits your needs.
Do you offer free samples?
Yes. We provide free samples so you can test fiber dispersion, mix compatibility, and performance before placing a bulk order. Shipping costs may apply depending on your location.
Can you customize fiber length or packaging?
Absolutely. We offer OEM services including custom fiber lengths (beyond the standard 3/6/12/18 mm), branded packaging, and private labeling. Minimum quantities apply for custom runs.
How does PAN fiber compare to steel fiber on cost?
PAN fiber typically costs 20–40% less per cubic meter of reinforced concrete compared to steel fiber. Additionally, PAN fiber eliminates corrosion-related maintenance costs and requires no special handling equipment.
What certifications do your products hold?
Our PAN fiber is manufactured under ISO 9001 and B/T19001-2016 quality management systems. Products are tested to ASTM, CABR, and ICBO protocols. Full certification documents are provided with each shipment.
