China's leading manufacturer of reinforced polypropylene fibers, offering comprehensive fiber solutions.
Polyacrylonitrile fiber (often abbreviated as PAN fiber) is a high-performance synthetic fiber made from acrylonitrile monomers. Unlike generic PP fibers, its rigid molecular structure delivers exceptional tensile strength, alkali resistance, and thermal stability—making it the top choice for infrastructure projects where concrete must withstand extreme weather, chemical exposure, or dynamic loads.
As cited in the American Concrete Institute (ACI) 544.3R-19 Guide, PAN fiber outperforms most synthetic fibers in long-term durability, with a 25-year service life in concrete structures compared to 10-15 years for standard PP fiber. It’s also non-corrosive, eliminating the risk of rust staining common with steel fiber reinforcement.

| Product Type | Material | Tensile Strength (MPa) | Alkali Resistance (%) | Thermal Stability (℃) |
|---|---|---|---|---|
| High-Modulus PAN Fiber | 100% Virgin Polyacrylonitrile | ≥800 | ≥98 | ≤220 |
| Alkali-Resistant PAN Fiber | Coated Virgin PAN | ≥750 | ≥99 | ≤230 |
| Short-Cut PAN Fiber | Virgin PAN | ≥700 | ≥97 | ≤210 |
Polyacrylonitrile fiber has 2x higher tensile strength and 98% alkali resistance, compared to PP fiber’s 60% alkali resistance. This makes PAN fiber ideal for long-term infrastructure projects, while PP fiber is better for low-stress applications like residential concrete.
Yes. Our coated PAN fiber offers ≥99% alkali resistance, making it suitable for concrete structures exposed to harsh chemical environments (e.g., dams, sewage treatment plants). It meets ASTM C1116-19 standards for alkali resistance.
