What Is LANDU NOVASTAR™ Polyacrylonitrile (PAN) Fiber?
NOVASTAR™ Polyacrylonitrile (PAN) Fiber is a high-performance synthetic, bundled monofilament fiber designed to reinforce asphalt and concrete compositions. Produced from 100% polyacrylonitrile, it exhibits high strength-to-weight ratios, excellent dimensional stability, and outstanding chemical resistance.
Its micro-scale monofilament structure enhances asphalt-aggregate bonding, controls microcracking, and improves overall fatigue resistance. The fiber's uniform dispersion ensures even reinforcement throughout asphalt or concrete mixtures, eliminating weak zones and improving flexibility under thermal and dynamic loads.
Unlike conventional polypropylene fibers, PAN Fiber retains its integrity even at temperatures above 200°C, offering superior heat resistance, which is critical for hot-mix asphalt applications.

Key Benefits of NOVASTAR™ Polyacrylonitrile (PAN) Fiber
Outstanding Crack Resistance
PAN Fiber forms a dense micro-reinforcement network within asphalt and concrete, bridging potential crack points and distributing mechanical stress evenly. This prevents early cracking from temperature variations, heavy loads, or dynamic impacts.
Improved Asphalt-Aggregate Adhesion
Surface-treated fiber strands increase the interfacial bonding area between asphalt binder and aggregates, preventing stripping and improving mixture cohesiveness under thermal cycling.
High Temperature & Chemical Stability
With a melting point exceeding 200°C, PAN Fiber remains stable during asphalt mixing and compaction processes, maintaining its reinforcement effect throughout production. It resists degradation from alkalis, acids, oil residues, and bitumen, ensuring consistent long-term performance.
Enhanced Rutting and Fatigue Resistance
By reinforcing the internal matrix, NOVASTAR™ PAN Fiber significantly improves resistance to rutting, plastic deformation, and fatigue failure, leading to longer-lasting pavements even in high-traffic or high-temperature zones.
Excellent Dispersion and Workability
Engineered for consistent dispersion, the fiber mixes smoothly into both asphalt and concrete without clumping, maintaining uniform distribution for predictable mechanical performance.
Extended Service Life and Cost Efficiency
Better adhesion, reduced cracking, and improved stability translate into lower maintenance frequency and cost over the life cycle of paved surfaces.
