PFOAM™

PFOAM has exceptionally high thermal conductivity comparable to that of copper and aluminum with significant weight savings.

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

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

  • Thermal management heat sinks manufactured from graphite foam 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 any harsh environments
  • Non-flammable in bulk form and oxidation resistant in most oxidizing atmospheres
  • EMI and 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 any environmental degradation in any challenging environment
  • Highly fire resistant
