The output of the capacitor film industry continues to grow and the market development will continue to improve in the future.

Capacitive film refers to electrical grade plastic film used as dielectric material for film capacitors. According to different materials, it can be divided into polyester capacitor film, polypropylene capacitor film, polystyrene capacitor film, polycarbonate capacitor film, polyimide capacitor film and other types; according to the thickness, it can be divided into 2.0μm capacitor film , 2.5μm capacitive film, 2.8μm capacitive film, 3.5μm capacitive film, 3.8μm capacitive film, 4.5μm capacitive film and other types. At present, the capacitive films used in the domestic film capacitor market are mainly 3.5μm, 3.8μm, and 4.5μm thick, and are gradually moving towards 2.5μm and 2.8μm thick capacitive films.

According to the “China Capacitor Film Industry Market Monitoring and Future Development Prospects Research Report 2022-2026” released by the Industrial Research Center, In recent years, the number of new expansion projects in my country’s capacitor film industry has increased, and the scale of capacitor film production has continued to expand. At the same time, domestic research on theoretical technology and production processes of capacitor films has continued to deepen, and advanced technologies and processes are increasingly being used in actual production, driving the In order to improve the efficiency of domestic capacitor film production, my country’s capacitor film production has increased year by year. Among them, in 2020, my country’s capacitor film production was 152,700 tons; in the first half of 2021, my country’s capacitor film production was 85,000 tons.

From the perspective of competition in the capacitor film market, in China, after decades of development, my country’s capacitor film industry has considerable production scale and R&D strength. The industry has formed such companies as Hebei Haiwei Group Electronic Materials Co., Ltd., Anhui Tongfeng Electronics Co. Co., Ltd., Zhejiang Dadongnan Co., Ltd., Anhui Tongfeng Electronics Co., Ltd., Nantong Baizheng Electronic New Materials Co., Ltd. and other advantageous enterprises. At the same time, there are still some small and medium-sized production enterprises in the capacitor film industry. The production scale is at the thousand-ton level. Generally speaking, competition among enterprises is relatively fierce.

From the perspective of the development prospects of the capacitive film industry, first of all, capacitive film is an important functional film material and is a new material industry among the strategic emerging industries supported and developed by the country. Secondly, capacitive film is the core dielectric material of film capacitors. Its market demand is closely related to the market demand of film capacitors and its downstream application industries. Film capacitors are mainly used in electronics, home appliances, communications, electricity, LED lighting, new energy, etc. industries, the demand for film capacitors in these industries is still growing. Thanks to this, the consumer demand in the capacitor film industry will continue to grow.

Industry analysts said that although the capacitor film industry still has room for development in the future, investors in the capacitor film industry need to pay attention to the price fluctuations of its upstream raw materials. risks, the risk of relying on imports of main raw materials, market competition risks and technical risks. At the same time, companies need to pay attention to the industry’s cutting-edge application technologies and products, and actively develop capacitive film products that can meet the needs of cutting-edge fields.
