Pyrolytic Graphite

Highly Ordered Pyrolytic Graphite is a unique form of graphite decomposition of a hydrocarbon gas at very high temperature in a vacuum furnace. Ultra-pure product which is near theoretical density and extremely anisotropic. The material is deposited as graphene and grown onto a substrate giving it a layered composition with anisotropic properties. It has different properties across different planes. In the C plane (across its layers) it has low thermal conductivity, acting as an insulator. In the A-B plane it has very high thermal conductivity, acting as a superb conductor.

Highly Ordered Pyrolytic Graphite is a specialized with unique thermal, electrical and chemical properties including superior EMI performance. These materials have applications where extreme temperature up to 6000°F (3300°C) and corrosive environments exist, conducting heat across its (a-b) planar surface like copper and insulating like ceramics in the (c) thickness direction. As a result of our proprietary finishing process we achieve extremely low particulates and chemical resistance to fluorine-based gases that provide solutions to problems in plasma and semi-conductor etching systems. PG has been highly diamagnetic, conducive to enhanced imaging process for medical applications.

Pyrolytic Graphite Sheet is a heat spreading material with high thermal conductivity. This material is lightweight and highly flexible. It can be cut into custom shapes, making it extremely useful for applications with limited space. In addition, it has excellent thermal conductivity properties, 600 to 800 W/(m-K), which is twice as high as copper and three times as high as aluminum. PGS can also be used as a clean and efficient alternative to silicone grease.
