Product details

The High thermal conductivity silicone sheet is a kind of thermal conductivity medium material made of organic silicon rubber as the matrix, auxiliary thermal conductivity filler material, flame retardant and other functional additives. It is specially produced for the design scheme of transferring heat through the gap, It has good thermal conductivity and resilience. High thermal conductivity silicone sheet, low thermal impedance, high thermal conductivity, insulation and flame retardant. High thermal conductivity organic silicon material, soft, good compressibility, and self-adhesive. The high thermal conductivity silicone sheet can be used to fill the gap and complete the heat transfer between the heating part and the heat dissipation part. The compression performance is very good: because the material of high thermal conductivity silica gel is very soft, it has very strong compression performance, and has thermal conductivity and insulation performance in use. Depending on the application environment and the scope of use, the thickness can be adjusted according to the actual situation. The flexibility of the application is improved, and the operability and maintainability can reach very good standards. Easy to install and reusable: The high thermal conductivity silicone sheet can meet the needs of a variety of industries. It can be easily installed according to the actual situation and can be used repeatedly, so that material waste can be avoided. In use, it has the effect of shock absorption and sound absorption. This feature has been widely recognized and can meet the needs of a variety of environmental uses. Air can be pushed out of the contact surface: Install a high thermal conductivity silicone sheet between the heat source and the radiator to directly push the air out of the contact surface to avoid affecting the heat transfer between the contact surfaces, because the air is poorly conductive, if the air is not discharged , It will naturally affect the heat transfer between the contact surfaces and cause the use effect to be affected. The material has good adaptability and is suitable for aluminum substrates of various shapes, with good thermal conductivity and no scraps. The application of high thermal conductivity silicone sheet is very wide, as long as it is related to the heat dissipation of electronic devices, it can basically be used. It is used for the interface heat dissipation, shock absorption and buffering of heating components. PCB circuit board, 5G communication industry, automotive electronics industry, power supply industry (power converter), solar industry, backlight industry, home appliance industry, LED industry (high-power LED lamps), high-end medical equipment, new energy vehicles, power batteries It has very important application purposes.

Product Qualification

The High thermal conductivity silicone sheet preparation method of the and the high thermal conductivity silicone sheet belong to the technical field of thermal conductivity materials. First, a silicone oil solution is prepared; then a crosslinking agent, flame retardant, weight reducing agent, reinforcing agent and carbon nanotubes are added to the silicone oil solution, at room temperature Stir for 30-60min; then place the stirred solution in a stainless steel mold and seal, and carry out crosslinking reaction at room temperature to obtain a solvent-containing high thermal conductivity silicone sheet; finally, the solvent-containing high thermal conductivity silicone sheet is dried to obtain a high thermal conductivity silicone sheet The present invention has the advantages of easy availability of raw materials, and the integration of heat dissipation and high mechanical strength; high thermal conductivity silicone sheet wafer prepared by the method has broad application prospects in the field of heat dissipation of electronic components.
 

Product features and applications

High thermal conductivity silicone sheet is also a thermally conductive soft silicone sheet. It is one of the heat transfer interface materials.  it is a kind of high thermal conductive medium material with excellent thermal conductivity, excellent fireproof property, good buffer property, controllable self-adhesion, selectable thickness, adjustable color, high performance-to-price ratio, low thermal resistance, high suitability, softness and elasticity, protection of sensitive electronic devices, a kind of high thermal conductivity media material with stable quality. It plays a good role in linking the air distance between the heating body and the heat sink, has high thermal conductivity and high pressure resistance,  it is the best first choice for thermal conductive material to remove the air layer. High thermal conductivity silica gel sheet has high thermal conductivity, good electrical insulation (only for insulating thermal silica gel sheet), wide use temperature, good use stability, low consistency and good construction simplicity. At the same time, it has low oil separation (towards zero), high and low temperature resistance, water resistance, ozone resistance, and climate aging resistance. Products are widely used, especially the use of high-end electronic products, such as: automotive electronic modules (engines and wipers) power modules, high-power power supplies; calculator applications (CPU,GPU,USICS, hard drive), LED-TV/PDP Wait. And the bottom or frame of the radiator, high-speed hard disk drive, RDRAM memory module, micro heat pipe radiator, automobile engine control device, communication hardware, portable electronic device, semiconductor automatic test equipment. TFT-LCD notebook computer, computer host. High-power LED spotlights, street lamps, fluorescent lights, etc. The heat-generating power devices (integrated circuits, power tubes, thyristors, transformers, etc.) of electronic products and electronic equipment are in close contact with heat dissipation facilities (heat sink, aluminum housings, etc.) to achieve better heat conduction effect. Power devices (power supply, computers, telecommunications) and any places that need to be filled for heat dissipation.
