Polyacrylonitrile PAN Short Fibers for Bitumen & Concrete
Our polyacrylonitrile PAN short fibers are high-modulus synthetic reinforcing fibers for bitumen and concrete. With 13±1μm diameter, this PAN fiber features high tensile strength, excellent acid & alkali resistance, and UV stability. It effectively controls early-age cracks in asphalt mixtures, SMA pavement, bridge decks, airport runways, and mortar. Our PAN staple fiber disperses well and resists high temperatures in hot mix asphalt. We offer custom lengths and packaged specifications. We supply reliable anti-crack PAN fiber for road and construction projects worldwide.
PAN Short Fibers is an advanced organic fiber aimed at modern projects and construction. It offers many advantages, including high modulus, high tensile strength, acid resistance, alkali resistance, anti-corrosion, good dispersibility, high oil absorbency, and good chemical stability. It also performs well in bad weather and under strong light.

PAN Short Fibers Applying instructions
Compounding amount: generally, 1.0kg/m3, fiber in cement mortar is enough. Particularly, it depends on the design.
The proper amount of fiber in bitumen concrete depends on the traffic flux:
When the traffic flux is below 5000, the admixture quantity is 1.5~2.0kg/ton,
when the flux is about 5000~60000, the quantity is about2.5~3.0kg/ton,
when the flux exceeds 60000, the quantity is about 3.5kg/ton.
PAN Short Fibers Packing
0.9kg or 1.0kg per small bag, 20kg per big bag.
Also can be 1 kg per small bag, 20- 25 kg per compound paper bag.

Sodium Naphthalene Sulfonate (SNF) based admixtures are widely used as high-range water reducers in modern concrete production. By improving cement particle dispersion, SNF helps reduce water demand by around 18% to 28% while maintaining good workability and strength development. Its unique chemical
Global ocean freight keeps rising, with South America routes hit hardest. Traditional liquid PCE superplasticizer only has 40‑50% solid content. Water fills much of the container space, driving up logistics costs and increasing the risk of performance degradation during long‑distance hot sea transport. This article covers three main PCE forms: liquid, powder, and flake, and highlights the merits of flake or powder PCE superplasticizer. Cost simulation based on a 40'GP container shows that high‑solid solid‑form PCE greatly reduces freight cost per ton of active substance. With stable performance, long shelf life, low storage requirements, and good compatibility with ready‑mix concrete and dry mortar, it is a preferred cost‑saving solution for concrete admixture importers and distributors amid surging ocean freight.
