Graphite paper classification

Graphite paper classification

Graphite paper passes through a series of addition processes such as high carbon phosphorus sheet graphite, chemical treatment, high temperature expansion rolling and roasting. It has high temperature resistance, heat conduction, flexibility, resilience and excellent sealing performance. Graphite paper has excellent characteristics. According to its application, it can be divided into sealing graphite paper, thermal conductive graphite paper and conductive graphite paper.
1. Graphite paper for sealing
It has been widely used in electric power, chemical industry, instrument, machinery and other industries. It can replace traditional seals such as rubber and asbestos and be used as dynamic and static seals of machines, pipes, pumps and valves.
2. Heat conducting graphite paper
Thermal conductive graphite paper has excellent thermal conductivity and heat dissipation performance. It is mainly used in mobile phones, laptops and other electronic products.
3. Conductive graphite paper
It is commonly used in the production and processing of various conductive products.

Principle and industrial application of graphite paper

The heat conduction principle of graphite paper is that high temperature and heat conduct heat evenly along the two directions through the surface of graphite paper. Graphite paper can absorb part of the heat and take away the heat through the heat conduction on the surface of graphite paper, which plays the role of heat dissipation. The horizontal thermal conductivity of graphite paper is generally between w / m-k and the vertical thermal conductivity is between 10-20w / m-K, The thermal conductivity is directly proportional to the price of graphite paper.

Compared with traditional metal materials, the thermal conductivity of graphite paper is 3 ~ 5 times that of copper and aluminum. Ultra thin graphite paper is generally used for heat conduction applications of electronic equipment. Ultra thin graphite has low thermal resistance, 40% lower than aluminum and 20% lower than copper. Graphite paper can be cut into various shapes, and heat conduction graphite paper can be used for heat dissipation of electronic equipment.
