It is a polymer material silicone gasket that combines heat dissipation and electromagnetic wave countermeasures. It is suitable for the electronic field with heat dissipation and absorption needs. It is specifically designed to use gaps to transfer heat and absorb electromagnetic radiation. It can fill gaps, complete heat transfer between heating and cooling parts, and also serve insulation, shock absorption, sealing, and electromagnetic interference elimination functions. It can meet the design requirements of equipment miniaturization and ultra-thin design, has high processability and usability, and has a wide range of thickness applications. It is an excellent thermal conductivity and absorption filling material. It has certain flexibility, excellent insulation, compressibility, and natural surface viscosity, which can meet the requirements of automated production and convenient product maintenance, providing a good solution for thermal conductivity and electromagnetic shielding of electronic communication products.
