PocoFoam - Thermo Management Materials

PocoFoam is a revolutionary advancement in thermal management. This unique material is a lightweight, porous graphite foam with exceptionally high thermal conductivity and very efficient thermal energy transfer characteristics. PocoFoam is produced through a patented foaming process that creates a structure of highly graphitic aligned ligaments within the foam's cell walls. These ligaments are the key to the material's high thermal conductivity. They perform like high performance graphite fibers, wicking heat away from its' source. PocoFoam has proven to be 3 to 9 times more thermally conductive than typical lightweight carbon foams. PocoFoam also demonstrates thermal conductivity up to 10 times higher than metallic foam materials, such as aluminum foam. Since this exciting new material is an advanced open cell foam, weight savings are significant when compared to conventional thermal management materials like aluminum or copper. When compared to aluminum, samples of graphite foam are five times lighter yet demonstrate equal or greater thermal conductivity. In addition, with an active service area of more than 4 m 2 /g, PocoFoam's heat transfer efficiencies have been shown in laboratory testing to be significantly greater than aluminum or copper. Unlike traditional materials, PocoFoam is resistant to attack by most acids. This graphite foam can be purified when contamination is a concern. As the demand for smaller, lighter and more efficient thermal management systems increases, the need for advanced material solutions follows. PocoFoam's unexpected combination of thermal management properties and physical characteristics provide exciting design opportunities for new and existing applications. With PocoFoam, radical changes in the design of heat sinks, thermal spreaders and heat exchangers are on the horizon.
