Leading Polyacrylonitrile Fiber Supplier From China

Michem Chemical Fibers Co., Ltd. is a leading manufacturer and exporter of polyacrylonitrile (PAN) fiber with 12 years of expertise serving 50+ countries, including the USA, Brazil, Australia, and Germany. We’ve supplied PAN fiber to landmark infrastructure projects like the Brazilian Amazon Hydroelectric Dam and the Jakarta-Bandung High-Speed Rail, where durability and resistance to harsh environments are non-negotiable.
Our PAN fiber is engineered in partnership with the China Academy of Building Research and meets strict global standards (ASTM C1116, EN 14889, ISO 9001). In this guide, we’ll break down how our polyacrylonitrile fiber solves critical construction challenges, backed by third-party test data and real-world client results.

What is Polyacrylonitrile Fiber (PAN Fiber)?

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.

pan-fiber--Concrete-Reinforcement-for-Infrastructure

Concrete Reinforcement for Infrastructure

Ideal for dams, bridges, and high-speed rail, our PAN fiber prevents shrinkage cracking and improves structural integrity. For the Jakarta-Bandung High-Speed Rail, we supplied alkali-resistant PAN fiber to reinforce precast track slabs, reducing maintenance costs by 28% in the first 2 years.
Industrial-Flooring-Precast-Components

Industrial Flooring & Precast Components

Used in heavy-duty factory floors and precast concrete panels, our PAN fiber enhances impact resistance and reduces post-installation cracking. A German automotive plant reported a 30% drop in floor repairs after switching to our PAN fiber.
pan-fiber-for-Asphalt-Pavement-Reinforcement

Asphalt Pavement Reinforcement

PAN fiber improves asphalt’s crack resistance and fatigue life, extending pavement service by 25%. We supplied fiber to the Australian M1 Motorway expansion, where it withstood extreme temperature fluctuations in the Outback.
pan-fiber-for-Hydroelectric-Marine-Construction

Hydroelectric & Marine Construction

PAN fiber’s resistance to water and chemical corrosion makes it perfect for marine docks, flood barriers, and hydroelectric dams. The Brazilian Amazon Hydroelectric Dam project used our high-modulus PAN fiber to reinforce spillway concrete, withstanding 100+ year flood loads.

General FAQs

Frequently Asked Questions Questions

 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.

Absolutely! We offer free 500g samples to qualified global clients. Contact us to request a sample and get technical data sheets included.

PAN fiber’s high modulus and uniform dispersion create a 3D reinforcement network in concrete, preventing crack propagation under thermal stress, dynamic loads, or chemical exposure. It also eliminates the risk of corrosion associated with steel fibers.

Proper dissolution is critical for HEC performance:

  1. Dispersion: Add HEC slowly to vortex of agitated water (not vice versa)
  2. Particle Size: Use fine mesh grades (80-100 mesh) for faster dissolution
  3. Temperature: Start with cold water (15-25°C); heat after hydration
  4. pH Adjustment: Add acids/bases only after full hydration
  5. Time: Allow 20-30 minutes for complete hydration

Pro Tip: Pre-dispersing in glycerol or alcohol prevents lumping in high-shear systems.

Hydroxyethyl Cellulose pricing depends on:

  • Viscosity grade: Higher viscosity = higher price
  • Purity level: Industrial vs. cosmetic vs. pharmaceutical grade
  • Order volume: Bulk orders (FCL) receive significant discounts
  • Customization: Special particle sizes or packaging

Price Range (2024):

  • Industrial Grade: $3.50-5.50/kg
  • Cosmetic Grade: $5.50-8.00/kg
  • Pharmaceutical Grade: $8.00-15.00/kg
