Tight Weave Carbon Cordage


Tight Weave Carbon Cordage is a new product manufactured from our high-quality carbonized polymer thread (tow) woven into a “3D layup”. The resulting weave increases the density, tensile strength, and resistance to abrasion. Increased density produces a braid with higher electrical conductivity, making this cordage an excellent choice for flexible heaters in vacuum heat treating applications. The maximum service temperature in an oxidizing environment is 400℃ and in vacuum 2400℃. Material is stocked and ready for shipment.

Product Documentation


  • 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.


  • 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.
