Carbon cordage is braided using carbonized polymer thread also known as tow. The raw material for the fibers is made from PAN or Rayon. The continuous fibers are manufactured and then carbonized through a series of rollers, combined into bundles, and collected into spools for easy use. The cords are comprised of 4,000 to 36,000 individual filaments in a braided structure. Maximum service temperature in an oxidizing environment is 400℃ and in vacuum 2400℃.
