Shin-Etsu Chemical is developing a new series of thermal interface silicone rubber sheets for applications in electric vehicle components as high voltage device technology advances

TOKYO–(BUSINESS WIRE)–Shin-Etsu Chemical Co., Ltd., (Headquarters: Tokyo, President: Yasuhiko Saitoh) has developed a new thermal interface silicone rubber sheet, “TC-BGI Series”, for applications in electric vehicle components as the technology of high-voltage devices advances.

Currently, the demand for electric cars is increasing, starting with electric vehicles (EVs), and in the future, further widespread market growth is expected. Components used in electric cars need to be smaller and lighter, and to increase energy density, high voltage is needed for system voltage.

In order to meet these requirements, Shin-Etsu Chemical has continued to develop thermal interface silicone materials that can be used as heat dissipation measures for components of electric cars for which high voltage requirements are increasing.

This new product, “TC-BGI Series”, is a high hardness thermal interface silicone rubber sheet which has the combined characteristics of high voltage endurance and thermal conductivity which are achieved by means of our company’s technologies. , and this new product is available in 2 thicknesses: 0.2 mm and 0.3 mm.

The main features of this new product are:

1. It achieves voltage endurance assurance which is at the highest level in the industry. We can provide voltage endurance of 3kV with 0.2mm thickness and 5kV with 0.3mm thickness over the entire surface of a sheet. Additionally, we are in the process of developing a product that will provide voltage endurance greater than 4kV with 0.2mm thick sheet metal over the entire surface of the sheet metal.

2. It has a high thermal conductivity of 7W/m・K.

3. It has high hardness and at the same time high strength, and its workability is superior to that of the pad type.

4. Compared with non-silicone type, its long-term reliability is superior.

In order to enhance the performance and reliability of an automobile, heat dissipation material is essential, and various products and technologies to realize heat dissipation are being developed.

Shin-Etsu Chemical offers a very wide range of different types of silicone thermal interface materials. In addition to silicone rubber sheets, we offer pads, greases (oil compounds), fillers, liquid rubbers (adhesives and potting materials). Our wide variety of silicone thermal interface materials can meet the demand of various heat dissipation measurements.

Along with the development of these new products, Shin-Etsu Chemical is making progress to meet our customers’ various demands in areas such as technical support with thermal analysis technologies, and we manufacture and process according to the international standard for thermal analysis systems. automotive quality management (IATF16949:2016)-approved factories.
