Solid Pyrolytic Graphite Raw Material & Machined Components

GMI manufactures ultra pure (greater than 5ppm) Pyrolytic graphite using a high temperature Chemical Vapor Deposition (CVD) process. The material is grown onto a substrate giving it a layered composition. This also means it has different properties in different planes. In the C plane (across its layers) it has low thermal conductivity, acting as an insulator. In the A-B plane (with the layers) it has very high thermal conductivity, acting as a superb conductor.

Properties
• High Purity
• High Density
• High Strength
