What is Carbon Cordage?
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℃.
Tight Weave vs. Regular Weave
Our new 24K Tight Weave Carbon Cordage is fabricated from the same high quality carbon tow used on our standard cordage. The yarn is then set on a series of bobbins and woven into a “3D” layup resulting in a weave with excellent tensile strength and abrasion resistance. The increased density of our tight weave produces a braid with higher electrical conductivity and strength, making this product an excellent choice for flexible heaters in vacuum heat treating applications. The Standard weave is a looser twisted layup with less mechanical strength. If you need a different size, grade, or outgassing, please contact us directly for a quote.
Benefits
- High strength and lightweight.
- Excellent thermal stability and good corrosion resistance.
- High tensile and chemically inert to most chemicals from pH 0-14, excluding strong oxidizers like nitric or sulphuric acids.
Applications
- Sewing or banding carbon or graphite felts in vacuum inert atmosphere furnaces or pump packing.
- Wrapping of parts to provide insulation on certain sections and to hold parts in place.
- Quick repair applications where bailing wire will not work.
- Can also be used as heating cables due to the material’s electrical conductivity.
