CFOAM® 35 HTC

CFOAM® 35 HTC has exceptionally high thermal conductivity comparable to that of copper and aluminum with significant weight savings.

CFOAM® 35 HTC graphite foam is a graphitized, lightweight, highly-oriented and open-cell carbon foam produced from mesophase pitch feedstock. CFOAM® 35 HTC graphite foam has exceptionally high thermal conductivity comparable to that of copper and aluminum with significant weight savings. In addition to its high thermal conductivity, CFOAM® 35 HTC also demonstrates high electrical conductivity, high strength and a low coefficient of thermal expansion. CFOAM® 35 HTC is also easily machinable, chemically inert, corrosion free, resistant to harsh environments, and resistive to oxidation up to 400°C.

We manufacture and produce CFOAM® 35 HTC at a scale, cost, and commercial output rate to penetrate already identified markets including, but not limited to:

  • Thermal management heat sinks for LED lighting, reducing weight, and increasing life
  • Lightweight and efficient heat exchangers for commercial military aircraft
  • Industrial heat exchangers for enhanced thermal heat transfer in single or multi-phase industrial heat exchanger products
  • Electronics component cooling
  • Automotive applications providing enhanced cooling in a smaller, lighter weight unit
  • Solar improving photovoltaic panel efficiency

Features

  • High thermal conductivity per unit weight
  • Low coefficient of thermal expansion
  • High compressive strength
  • Lower weight relative to aluminum (1/6th) and copper heat sinks (1/22nd)
  • Inert in corrosive and harsh environments
  • Non-flammable in bulk form and oxidation resistant in most oxidizing atmospheres
  • Acoustic shielding

Benefits

  • High thermal conductivity and high thermal diffusivity enables superior rate of heat dissipation in thermally critical applications
  • 22x lighter than copper and 6x lighter than aluminum
  • Inert characteristics enable high resistance to environmental degradation in challenging environments
  • Highly fire resistant
