Thermal pads have a wide range of applications and local companies have independent research and development capabilities.

Thermal pad refers to filling the air gap between the heating device and the heat sink or metal base. Thermal conductive pads have the characteristics of high thermal conductivity, good compressibility, good softness, and high elasticity, and are widely used in electronic and electrical, automobile manufacturing and other fields. According to different raw materials, thermal pads can be divided into two categories: silicone-free thermal pads and thermal silicone pads.

Thermal silicone gaskets are currently the most widely used thermal gaskets. They use silicone oil as the main raw material and have the advantages of high temperature resistance, good insulation, high thermal conductivity, and aging resistance. However, long-term use can easily cause silicone oil to leak, causing environmental pollution. Silicone-free thermal pads use special resins such as acrylic acid as the main raw material. They have the advantages of green environmental protection and controllable rigidity, but the production cost is relatively high.

Thermal pads have a wide range of applications, including electronics and electrical, automobile manufacturing, etc. In the electronic and electrical fields, thermal pads can be used in semiconductor automatic test equipment, micro heat pipe radiators, memory modules and other products; in the automotive manufacturing field, thermal pads are mainly used in automotive thermal management systems to conduct heat from power batteries. to the liquid cooling tube to achieve the heat dissipation effect. As downstream demand continues to grow, the development space of the thermal pad industry continues to expand. According to the “2023-2028 China Thermal Pad Industry Market In-depth Research and Development Prospects Forecast Report released by the Industrial Research Center, The global thermal pad market size will reach 7.23 billion yuan in 2022, a year-on-year increase of 8.2%.

The global thermal pad market is mainly concentrated in European and American countries. Manufacturers include the American Laird Technology Group (LAIRD), the American 3M Company, the American Parker Company (Parker), the American Bergquist Company (Bergquist), and the French Saint-Gobain Group (SAINT- GOBAIN), German Henkel Group (Henkel), British Boyd Company (Boyd), etc. The American company Beggs is the world’s leading thermal pad company, and its independently developed SIL-PAD thermal insulating pad series products rank among the world’s leading companies in sales.

The main manufacturers of thermal pads in my country include Shenzhen Aochuan Technology Co., Ltd., Dongguan Shengyuan New Material Technology Co., Ltd., Shenzhen Huaneng Zhiyan Electronics Co., Ltd., Shenzhen Jinling Tongda Electronics Co., Ltd., Shanghai Alade Industrial Co., Ltd., Kunshan Yuling Thermal Technology Co., Ltd., Guangzhou Zhongshi Technology Co., Ltd., etc. In recent years, driven by positive factors such as national policy support, the independent research and development capabilities of my country’s thermal pad companies have continued to improve. Zhongshi Technology focuses on the R&D, production and sales of absorbing materials, thermal conductive materials and shielding materials. The company’s independently developed thermal pads can be used in millimeter wave radars.

Industry analysts said that thermal pads, as a representative product of thermal conductive materials, have the characteristics of high thermal conductivity and good compressibility. Widely used in many fields. As market demand is gradually released, the development space of the thermal pad industry continues to expand. There are many thermal pad manufacturers in my country. With the continuous improvement of independent research and development capabilities, the industry will gradually develop in a high-end direction.
