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
