1.Use and scope of application

The main raw material of graphite paper is natural flexible expandable graphite. Natural flexible expandable graphite is a non-metallic element, but it has the thermal conductivity of metal materials, and has high plasticity and chemical stability.

There are many specifications of graphite paper. According to the thickness of graphite paper, the specifications of graphite paper can be divided into: 0.025mm, 0.032mm, 0.05mm, 0.07mm, 0.1mm, 0.15mm, 0.2mm, 0.25mm and more than 1mm-5mm. Among them, graphite paper of 1mm-5mm or more needs to be customized.

With the rapid development of electronic products, the degree of refinement of chips is getting higher, faster and faster, and the volume is getting smaller and smaller. The heat generated by the chip is getting larger and larger, but the cooling space of electronic products is getting smaller and smaller. The requirements for materials are getting higher and higher. Whether it is a mobile phone, smart phone, tablet computer, or other digital product manufacturers, there is an urgent need for a highly reliable thermal conductive material. Graphite paper, also known as graphite heat sink, is a new type of thermally conductive heat dissipation material. Graphite paper has complete specifications. With its lighter, thinner, and higher thermal conductivity, it has solved smart phones, tablets, digital Heat conduction and heat dissipation of electronic products such as products and LED lamps.

4.Product Performance&Graphite paper thermal conductivity and heat dissipation principle

Thermal Transfer	Hot average temperature
Thermal transfer - transfer the heat from the heat source to the heat sink fast ( heat And the heat sink can not in the same interface )	Hot average temperature - the heat from point average temperature heat quickly spread to larger heat surface , thereby increasing the effective cooling area , to achieve rapid cooling effect .
