Precursor: The Foundation of Performance

Every high-performance carbon fiber begins with a precisely engineered precursor — and at Aksa Carbon, we control this process from chemistry to conversion.

Aksa Carbon |

Our proprietary PAN-based precursor is developed through advanced polymerization and spinning technologies, ensuring consistent molecular alignment, purity, and thermal stability.These properties directly translate into superior tensile strength, modulus and surface uniformity in the final carbon fiber.

Technical Specifications

As one of the few fully integrated carbon fiber producers worldwide, Aksa Carbon leverages decades of expertise in acrylonitrile chemistry, process optimization and fiber morphology control to achieve unmatched quality and scalability.
