3.Product features and applications of High conductivity heat dissipation natural graphite sheet single sided tape
High conductivity heat dissipation natural graphite sheet single sided tape, is made of graphite powder as the raw material, and the composite thermal conductivity material (natural graphite heat dissipation film has high thermal conductivity) is processed into thermal conductivity sheets of various thicknesses and specifications, which is convenient for forming and processing and has a thinner , It has the characteristics of better heat conduction and heat dissipation, low thermal resistance, long service life, simple replacement, easy operation and so on. The special properties of the high-conductivity heat-dissipating natural graphite sheet single-sided tape: 1. High temperature resistant type: the melting point of graphite is 3850±50ºC, the boiling point is 4250ºC, Even after very high temperature arc burning, the weight loss is very small and the coefficient of thermal expansion is very small. The strength of graphite increases with the increase of temperature. At 2000°C, the strength of graphite doubles. 2. Electrical conductivity and thermal conductivity: The electrical conductivity of graphite is one hundred times higher than that of general non-metallic minerals. The thermal conductivity exceeds that of metal materials such as steel, iron, lead. Thermal conductivity decreases with increasing temperature, even at higher temperatures, graphite becomes an insulator. The chemical composition of thermally conductive graphite sheet (highly conductive and heat-dissipating natural graphite sheet) (Thermal Flexible Graphite sheet) is mainly a single carbon (C) element, which is a natural element mineral. Graphite can conduct electricity because each carbon atom in graphite only forms 3 covalent bonds with other carbon atoms, and each carbon atom still retains 1 free electron to transfer charge. In the metallurgical industry, natural flake graphite can be used to produce refractory materials such as magnesia-carbon bricks and aluminum-carbon bricks due to its better oxidation resistance. Natural flake graphite has good lubricity and is often used as an additive in lubricating oil. High-conductivity heat-dissipating natural graphite sheet single-sided tape has been widely used in many fields such as electronics, lighting, aviation, PDP, LCD TV, NotebookPC, UMPC, Flat Panel Display, MPU, Projector, PowerSupply, LED lighting, etc. The combination of heat dissipation and heat insulation properties of the highly conductive heat dissipation natural graphite sheet single-sided tape has become an outstanding material choice for thermal management solutions.

4.Product details of  High conductivity heat dissipation natural graphite sheet single sided tape
High conductivity heat dissipation natural graphite sheet single sided tape, the main raw material of natural graphite, the process characteristics mainly depend on its crystalline form. Minerals with different crystal forms have different industrial values and uses. There are many kinds of natural graphite. according to the different crystal forms, natural graphite is divided into three types: dense crystalline graphite, flake graphite and cryptocrystalline graphite (earthy). There are mainly two types of flake graphite and cryptocrystalline graphite (earthy) in China. Natural graphite: The crystal development is relatively complete, the graphitization degree of flake graphite is more than 98%, the friction coefficient is small, the lubricity is the best, and the plasticity is the highest. For graphite powder of the same purity and particle size, the transmission of natural flake graphite The thermal performance and electrical conductivity are the best. For the first time in lithium batteries, flake graphite has a coulombic efficiency of 90%~93% and a reversible capacity of 340~370mAh/g, so it is the most mainstream negative electrode material. Highly conductive and heat-dissipating natural graphite sheet single-sided tape, conductive and heat-dissipating, small space occupation, light weight, uniform heat conduction in two directions, eliminating "hot spot" areas. Because carbon is a non-metallic element, but it has the electrical and thermal conductivity of metal materials, and has plasticity like organic plastics, and  such as special thermal properties, chemical stability, lubrication and coating on solid surfaces, etc. Some good process performance. Thus, it is known that the highly conductive heat dissipation natural graphite sheet single-sided tape is conductive, and the film polymer compound can be chemically used to obtain a graphitized film under high temperature and high pressure. The thermal conductive graphite sheet has a thermal conductivity in the range of 300-1500 W/m-K in the plane. Highly conductive heat dissipation natural graphite sheet single-sided tape has been widely used in the communication industry, medical equipment, SONY/DELL/Samsung notebooks, ZTE mobile phones, Samsung PDP, PC memory sticks, LED substrates and other heat dissipation. It is also widely used in smart phones, ultra-thin PCs, LED TVs, LED spotlights, downlights, bulb lights, high bay lights, etc.


5.Product Qualification of the High conductivity heat dissipation natural graphite sheet single sided tape
High conductivity heat dissipation natural graphite sheet single sided tape, the natural graphite is formed by the transformation of carbon-rich organic matter under the long-term action of high temperature and high pressure geological environment, which is the crystallization of nature. Highly conductive heat dissipation natural graphite sheet single-sided tape can be used for the manufacture of mobile phone circuit boards, Include a graphite sheet, the upper surface of the graphite layer is coated with a polyimide film, the upper surface of the polyimide film is coated with a coating layer, the upper surface of the coating layer is coated with a heat insulating foaming resin layer, and the lower surface of the graphite layer is coated with a thermal conductive silica gel layer. its structure design is reasonable. Through the setting of thermal conductive silica gel, the one-sided tape of high conductivity and heat dissipation natural graphite sheet can contact seamlessly with the parts to be dissipated, improve its heat transfer efficiency, have the directionality of heat conduction, and improve the strength of graphite lamin. so that it is not easy to fall powder and fracture phenomenon, prolong its service life.
