In the context of globalization, the domestic defoamer market is undergoing an important transformation from relying on imports to independent research and development and import substitution. With the improvement of domestic technology and the promotion of environmental policies, the research and development of imported substitute defoamers has become a hot topic in the industry. In recent years, domestic enterprises have made significant progress in technological innovation in the field of defoamers. By introducing, digesting, absorbing and innovating, domestic enterprises have developed various high-performance imported substitute defoamers, such as bio based defoamers, high-efficiency and low toxicity defoamers, etc.

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. With the increasingly strict environmental policies, domestic enterprises are accelerating the research and development of environmentally friendly imported substitute defoamers to meet the market's demand for green and environmentally friendly products.

In the future, domestic imported substitute defoamers will pay more attention to technological upgrades and performance improvements to meet the needs of high-end markets and special fields. With the continuous expansion of the domestic defoamer market, imported substitute defoamers will actively expand domestic and international markets and enhance international competitiveness. Environmentally friendly imported substitute defoamers will become the mainstream direction of future development, and domestic enterprises will increase their research and development efforts to promote green and intelligent development.

Significant achievements have been made in the research and development of domestically imported substitute defoamers, but there is still a need to strengthen technological innovation and market expansion to enhance international competitiveness. In the future, with the improvement of technological level and the promotion of environmental policies, the import substitution of defoamers will usher in a broader development prospect.
