In the context of globalization, the domestic defoamer industry is undergoing 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, meeting the market's demand for green and environmentally friendly products. 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. Domestic enterprises are strengthening industry university research cooperation with universities and research institutions, promoting technological innovation and achievement transformation, and improving the technological level and market competitiveness of imported substitute defoamers.

With the rapid development of the domestic economy and the promotion of environmental policies, the demand for defoamers in the domestic market continues to grow. As an important component of the domestic defoamer market, imported substitute defoamers will usher in broader market opportunities. With the improvement of domestic import substitution defoamer technology and the increase of market awareness, domestic enterprises will actively expand their international markets and enhance their international competitiveness.

With the increasingly strict environmental policies, the demand for environmentally friendly imported substitute defoamers in the market will continue to grow. Domestic enterprises should seize this opportunity, increase research and development efforts, and promote green and intelligent development.

In the future, the domestic import of substitute defoamers will usher in a broader development prospect. With the improvement of technological level and the promotion of environmental policies, imported substitute defoamers will pay more attention to technological upgrading and performance improvement to meet the needs of high-end markets and special fields. At the same time, domestic enterprises should actively expand market channels, enhance the market awareness and competitiveness of imported substitute defoamers, and promote the healthy and orderly development of the domestic defoamer industry.
