Polyacrylonitrile fiber （PAN fiber） has higher tensile strength, larger initial modulus and stable chemical properties. Therefore, the fiber has acid and alkali corrosion resistance, light resistance and weather resistance, and has good dispersion and oil absorption.PAN fibers are suitable for fields that require high thermal load, chemical resistance, and UV stability. PAN fiber is also an economical alternative to aramid fiber.
