Tenabrix - Reliable PAN Fiber Supplier
Polyacrylonitrile Fiber, also known as PAN fiber or acrylic fiber, is a fine, light yellow synthetic fiber widely recognized for its exceptional strength and durability. It is also the primary raw material for carbon fiber production. At Tenabrix, we manufacture premium Polyacrylonitrile Fiber to enhance the crack resistance, structural integrity, and long-term performance of concrete and cement-based materials.

China's Leading Polyacrylonitrile Fibers Manufacturer
PAN fibers should be properly tested with your specific concrete mix before full-scale application. They are best dispersed using sand and aggregate friction to form an even reinforcement network throughout the concrete matrix.

Maximize Concrete Performance with the Benefits of Tenabrix Polyacrylonitrile Fiber
Enhanced Concrete Durability
Reduces the formation and propagation of micro-cracks, extending the lifespan of concrete structures exposed to harsh environments.
High Tensile Strength
Provides exceptional tensile resistance, improving structural integrity and enabling concrete to withstand heavy loads.
Corrosion Resistance
Unlike traditional steel fibers, PIF resists corrosion, making it ideal for concrete in moist, acidic, or otherwise aggressive conditions.
Improved Fatigue Resistance
Increases the fatigue life of concrete, making it suitable for cyclic load-bearing structures such as bridges, highways, and airport pavements.
Polyacrylonitrile Fibers Deliver Outstanding Performance Across Applications
Industrial Flooring
Polyacrylonitrile fibers enhance the toughness and crack resistance of concrete floors in industrial settings. They help prevent shrinkage and micro-cracks caused by heavy machinery, forklifts, and continuous foot traffic. The result is a long-lasting, low-maintenance surface that maintains structural integrity and smoothness over time.
Bridge Decks
PAN fibers improve the tensile strength and fatigue resistance of concrete in bridge decks, helping them withstand repeated traffic loads, vibration, and temperature variations. By controlling micro-cracking and reducing maintenance needs, these fibers extend the service life of bridges and enhance overall safety.
Tunnel Linings
In tunnel construction, polyacrylonitrile fibers provide superior crack control and impact resistance, protecting the lining from early-age cracking and long-term stress. Their corrosion resistance ensures stability in high-humidity environments, making tunnels safer and more durable under constant structural and environmental loads.
Airport Runways
PAN fibers strengthen concrete against thermal stress, cyclic aircraft loads, and environmental wear. By minimizing micro-cracking and improving fatigue resistance, they enhance runway performance, reduce maintenance frequency, and ensure safety under demanding operational conditions.
