Thermal conductive silicone sheets have wide application fields and good industry development prospects

Thermal silica gel sheet, also known as thermal silica gel sheet, thermal silica gel gasket, thermal silica gel pad, is a thermal conductive dielectric material that uses silica gel as the base material, adds various auxiliary materials such as metal oxides, and is synthesized through a special process. Thermal conductive silicone sheets have the advantages of good insulation performance, good thermal conductivity stability, and good compression performance. They are widely used in automotive machinery, electronic products, household appliances and other fields. According to different properties and materials used, thermally conductive silicone sheets can be divided into glass fiber thermally conductive silicone sheets, strong adhesive thermally conductive silicone sheets, ordinary thermally conductive silicone sheets, silicone cloth-backed thermally conductive silicone sheets, etc.

The main preparation process of thermally conductive silicone sheets includes raw material preparation, tablet molding, cutting, plasticizing, inspection, etc. Molding is the core link. Currently, calendering and flat plate pressing are the most commonly used molding processes for thermally conductive silicone sheets. Calendering is suitable for continuous production and has the advantages of high work efficiency and good finished product quality, but it has high operating costs. Flat press molding usually uses a flat vulcanizer to complete the molding operation. The production process is relatively simple, but the work efficiency is low.

Silicone is the base material of thermally conductive silicone sheets, accounting for nearly 60% of its production costs. my country is a major producer of silica gel, and its production areas are concentrated in Guangdong and other places. In recent years, as technology has matured, my country’s silicone production has been exported overseas while meeting local market demand. According to statistics from the General Administration of Customs of China, my country’s silica gel export volume reached 130,000 tons in 2021, a year-on-year increase of 11.1%. The sufficient supply of raw materials lays the foundation for the development of my country’s thermally conductive silicone sheet industry.

According to the “2023-2028 China Thermal Silicone Sheet Industry Market In-depth Research and Development Prospects Forecast Report released by the Industrial Research Center, Thermal conductive silicone sheets are used in a wide range of fields, including automotive machinery, electronic products, household appliances, etc. In the field of automotive machinery, thermally conductive silicone sheets can be used to dissipate heat from new energy vehicle battery packs. According to statistics from the China Association of Automobile Manufacturers, my country’s new energy vehicle production will reach 7.058 million units in 2022, a year-on-year increase of 96.9%. With the rapid development of the new energy automobile industry, the market size of my country’s thermally conductive silicone sheet will continue to expand.

There are many thermally conductive silicone sheet manufacturers in my country, and the market competition is relatively fierce. Jiangsu Keqiang New Materials Co., Ltd., Dongguan Yi’an Technology Co., Ltd., Shenzhen Huatianqi Technology Co., Ltd., Hubei Huitian New Materials Co., Ltd., etc. are major players in my country’s thermally conductive silicone sheet market.

Industry analysts said that thermally conductive silicone sheets have excellent comprehensive properties and are widely used in various major fields. As market demand continues to grow, thermal conductivity The silicone sheet industry will usher in broad development prospects. my country is a major silica gel producer with sufficient output and raw material advantages that provide favorable conditions for the development of the thermally conductive silicone sheet industry. In the future, as local companies continue to innovate in production technology, the output and quality of thermally conductive silicone sheets in my country will further improve.
