Graphite paper is made of high carbon flake graphite through chemical treatment and high temperature expansion rolling. Its appearance is smooth, without obvious bubbles, cracks, wrinkles, scratches, impurities and other defects. It is the base material for the manufacture of various graphite seals. It is widely used in dynamic and static sealing of machines, pipes, pumps and valves in electric power, petroleum, chemical, instrumentation, machinery, diamond and other industries. It is an ideal new sealing material to replace traditional seals such as rubber, fluoroplastics and asbestos. .
The specifications of graphite paper mainly depend on its thickness. Graphite paper with different specifications and thicknesses has different uses. Graphite paper is divided into flexible graphite paper, ultra-thin graphite paper, sealed graphite paper, thermally conductive graphite paper, conductive graphite paper, etc. Different types of graphite paper It can play its due role in different industrial fields.
6 characteristics of graphite paper:
1. Ease of processing: Graphite paper can be die-cut into different sizes, shapes and thicknesses, and die-cut flat boards can be provided, and the thickness can range from 0.05 to 1.5m.
2. High temperature resistance: the maximum temperature of graphite paper can reach 400℃, and the minimum can be lower than -40℃.
3. High thermal conductivity: The maximum in-plane thermal conductivity of graphite paper can reach 1500W/mK, and the thermal resistance is 40% lower than that of aluminum and 20% lower than that of copper.
4. Flexibility: Graphite paper can be easily made into laminates with metal, insulating layer or double-sided tape, which increases design flexibility and can have adhesive on the back.
5. Lightness and thinness: Graphite paper is 30% lighter than aluminum of the same size and 80% lighter than copper.
6. Ease of use: The graphite heat sink can be smoothly attached to any flat and curved surface.
When storing graphite paper, pay attention to the following two matters:
1. Storage environment: Graphite paper is more suitable to be placed in a dry and flat place, and it is not exposed to the sun to prevent it from being squeezed. During the production process, it can reduce collisions; it has a certain degree of conductivity, so when it needs to be stored, it should be kept away from the power source. electric wire.
2. Prevent breakage: The graphite paper is very soft in texture, we can cut it according to the requirements, in order to prevent them from breaking during storage, it is not suitable for folding or bending and folding at a small angle. General graphite paper products are suitable for cutting into sheets.
