Soft Felt

Carbon felt and graphite felt are designed for use as high temperature insulation in vacuum furnaces and inert gas furnaces. Our PAN based carbon and graphite felt is light in weight and has low thermal conductivity. It can be used in oxidizing temperatures up to 400 °C and in vacuum or protective atmospheres up to 3200 °C.

The carbon and graphite felts are processed from a rayon precursor and fired to graphitizing temperatures. Primarily used as high temperature insulation in inert or vacuum atmospheres offering high stability through rapid thermal cycling.

Distinctive Characteristics：

• High stability with low shrinkage
  • Low density and thermal mass
  • Greater efficiency in heating and cooling
  • Low thermal conductivity
  • Uniformity throughout the material
  • Available in different lengths, widths, and thickness
  • Can be halogen purified to reduce impurity levels into the ppm range
