Local companies are accelerating their entry into the electrochromic film market, and industry concentration is expected to continue to increase in the future.

Electrochromism (EC) refers to the phenomenon of stable and reversible color changes in the optical properties (reflectivity, transmittance, absorptivity, etc.) of materials under the action of an electric field or current. Materials with electrochromic properties are electrochromic Material. Electrochromic films refer to thin film products prepared from electrochromic materials. The main types include indium tin oxide (ITO) color-changing film, cobalt tetroxide (Co3O4) color-changing film, tungsten oxide (WO3) color-changing film, and vanadium pentoxide. (V2O5) color changing film, etc.

According to the“China Electrochromic Film Industry Market Monitoring and Future Development Prospects Research Report 2023-2027” released by the Industrial Research Center It shows that the electrochromic film has good ionic conductivity, excellent electrochemical redox reversibility, long service life, high color change sensitivity, strong chemical stability, wide working range, high coloring efficiency, and low cost. It is mainly used as thermal insulation window film, porthole sunshade film and other products in automobiles, aviation, offices, homes, banks, building curtain walls and other scenarios.

The emergence of electrochromic films can be traced back to the initial discovery of the electrochromic phenomenon in the early 18th century. Since then, under the background of accelerating related research processes in the 1960s, electrochromic films have gradually entered the early stage of industrialization. After long-term research and development, electrochromic films have now become a type of industrial material with wide applications and powerful performance, and its industry has entered a period of rapid development.

Among them, automobile glass is the main application scenario of electrochromic film. In this scenario, electrochromic film mainly plays the role of automatically adjusting the light transmittance of the glass, reducing and preventing dazzling conditions, thereby achieving the purpose of reducing driving safety hazards. At the same time, It can also achieve the purpose of lowering the temperature inside the car and reducing the power consumption of air conditioning. It is one of the advanced materials needed in the automotive field. Currently, driven by the continued growth of domestic automobile production and sales, the market demand for electrochromic films continues to increase.

As the potential of the domestic electrochromic film market continues to highlight, the number of companies in the market is increasing. The main companies include Jumei Film Technology, Huichuang Glass Technology, Xingye New Materials, BenQ Materials, Huake Chuangzhi Technology, and Kewei Thin film new materials, Taihongtong Optoelectronics Technology, Qiwei Optoelectronics new materials, etc. However, at present, most domestic electrochromic film companies are small and medium-sized enterprises, and the industry concentration is still relatively low.

Industry analysts said that Jumei Thin Film Technology is one of the leading companies in the domestic electrochromic film market , currently the company has 2 electrochromic film production lines and multiple slitting lines, and can achieve an annual production of 2 million vehicles with electrochromic film. In the future, as the technical level of leading local companies continues to improve and related research and development processes continue to accelerate, the concentration of the domestic electrochromic film industry is expected to continue to increase, and the industry has broad prospects for development.
