Cool Polymers Inc. has developed a thermally conductive polymer for heat-sink applications.
The Warwick, R.I., firm said CoolPoly is 100-500 times more thermally conductive than standard plastics. It can be injection molded to replace nonconductive plastics and metal parts in electronics, medical, automotive, lighting and industrial equipment.
Cool Polymers claims CoolPoly´s heat transfer is similar to that of aluminum and other metals, but it weighs 40 percent less than aluminum. It is composed of mainly nonmetallic reinforcements, such as carbon and ceramic, in an engineering resin matrix.
Other properties that promise broad application are low coefficient of thermal expansion and elimination of hot spots to provide better dimensional stability.
