In today's increasingly fierce global competition, the domestic defoamer industry is facing an important transformation from relying on imports to independent research and development and import substitution. Domestic enterprises have achieved significant results in technological innovation in the field of defoamers, and have developed various high-performance imported substitute defoamers. These products not only have excellent defoaming performance, but also have good environmental performance and biodegradability.

Domestic enterprises are actively seeking domestic substitution of raw materials to reduce production costs and enhance market competitiveness. Through independent and collaborative research and development, a domestically produced supply chain for defoamer raw materials has been initially formed in China, providing strong support for the research and development of imported substitute defoamers.

The domestic import substitution of defoamers has initially formed a certain market scale and achieved import substitution in some fields. In the future, with the continuous expansion of the domestic market and the promotion of environmental policies, the market prospects for imported substitute defoamers will be even broader.

Although domestic enterprises have achieved significant results in technological innovation in the field of defoamers, there are still some technical bottlenecks, such as the research and development of high-efficiency and low toxicity defoamers, and the localization of raw materials for substitution. The domestic defoamer market is fiercely competitive, and imported substitute defoamers are facing competition pressure from domestic and foreign enterprises. With the increasingly strict environmental policies, domestic imported substitute defoamers need to meet stricter environmental requirements, which puts higher demands on the research and production capabilities of enterprises.

In the future, domestic enterprises should increase research and development investment, strengthen technological innovation, break through technological bottlenecks, and improve the performance and quality of imported substitute defoamers. Domestic enterprises should actively expand their market channels and enhance the market awareness and competitiveness of imported substitute defoamers. Domestic enterprises should strengthen environmental management, raise environmental awareness, promote green and intelligent development, in order to meet the market demand for environmentally friendly imported substitute defoamers.
