Yuanwang™ PAN Fiber
PAN fiber, also known as acrylic fiber. It is made from polyacrylonitrile or copolymers containing more than 85% acrylonitrile. It can also be used as a raw material for polyacrylonitrile carbon fiber.
Although it appears fluffy, PAN fiber effectively prevents cracks after concrete hardens.
✅ It helps solve water leakage problems in buildings.
✅ It significantly extends the service life of structures.
✅ It is specially designed for use in construction materials like asphalt, concrete, and cement.
As a leading Chinese manufacturer of concrete additives, Yuanwang Group established its fiber division in 2020. The company started R&D on high-strength PAN fiber.
Yuanwang™ optimized the production process and improved the technology. We also developed testing methods and set quality standards. As a result, our scale production of high-strength PAN fiber production has now been realized.
Polyacrylonitrile Fiber Structure
PAN fiber is mainly made from a polymer with a molecular weight of around 100,000. It contains more than 85% acrylonitrile monomers. Its structure is a linear polymer chain.
To improve performance, comonomers like vinyl acetate or methyl acrylate are often added. Typical PAN fibers show a core–sheath composite structure. During processing, both structure and function can be adjusted. This allows the fiber to meet different application needs.
For example, PAN fiber made from acrylonitrile, methyl acrylate, and acryl sulfonic acid has the following structure:

Yuanwang Polyacrylonitrile Fiber Advantages
The side chains of PAN fiber contain many polar nitrile groups (–CN). These groups form strong polar interactions on the fiber surface. This improves bonding with the cement matrix in concrete.
It enhances stress transfer and helps stop crack propagation. It has a higher elastic modulus compared with polypropylene fibers. It has excellent UV resistance, high-temperature resistance and cold resistance.
Great Tensile Strength. Polyacrylonitrile fiber is a popular ingredient when reinforcement is needed in construction areas.
> Thermal Stability. Polyacrylonitrile based fiber can stand high temperatures without compromising strength and durability.
> Chemical Resistant. PAN widely used for other concrete or cement applications where chemical exposure is a concern.
Yuanwang Factory Production Process
1. Raw Material Preparation
Polymerization Reaction: Acrylonitrile (AN) is used as the main monomer and copolymerized with other monomers to produce copolymerized polyacrylonitrile resin.
2. Dissolution and Spinning
Dissolution: The copolymerized PAN resin is dissolved in a solvent to form a suitable spinning solution.
Spinning: The fiber is formed through wet spinning, dry spinning, or dry-wet spinning methods.
3. Post-Treatment
Washing: Removes residual solvents and impurities.
Stretching: Achieves the required fiber strength and length.
Drying: Removes moisture from the fiber.
Heat Setting: Stabilizes the fiber to ensure its shape and performance.
4. Special Treatments (e.g., Carbonization)

Polyacrylonitrile Uses - Yuanwang PAN Fiber
Yuanwang polyacrylonitrile fiber has many advantages, such as high tensile strength and UV resistance.
Yuanwang PAN reinforced fiber is also used in asphalt, concrete or cement. It improves the tensile, anti-fatigue, and bending strength of concrete. Adding fiber to cement helps to prevent the cracking of building materials
Concrete Formula with Polyacrylonitrile Fiber
Yuanwang supports OEM formula customization. Our team can assist in selecting additives and designing formulas based on your construction requirements.
>> Cement Concrete Dosage
The dosage of fiber per cubic meter of concrete is generally 0.5-1.0kg. However, the fiber dosage can be adjusted based on the variation in the amounts of sand, stone, and cement and the anti-cracking requirements of the project.
>> Asphalt Concrete Dosage
The recommended dosage of PAN fiber in asphalt concrete is typically around 0.3-0.5% by weight of the asphalt binder. This dosage can vary depending on the project requirements and the asphalt mix used.
