Shanghai Mac Corporation is a leading Polyacrylonitrile fiber manufacturer and supplier.

Polyacrylonitrile fiber is a high-performance synthetic fiber made from 100% polyacrylonitrile via wet spinning or dry-jet wet spinning. Its core value lies in serving as a high-efficiency reinforcement and functional material that disperses uniformly in cement-based materials, composite materials and textile substrates, effectively resisting cracking, enhancing tensile strength and improving structural stability. As a core precursor for carbon fiber production, it is also the foundational raw material for high-performance carbon fiber with high strength and modulus. It cannot be replaced by conventional synthetic fibers in high-end reinforcement scenarios, and it physically optimizes the mechanical and functional properties of base materials, significantly improving their durability, heat resistance and structural integrity. Polyacrylonitrile fiber is a key functional additive and raw material in modern high-performance concrete, advanced composite materials, aerospace components, textile reinforcement and new energy material fields for crack control, structural reinforcement and high-performance material preparation.
