Nowadays, the research and development of imported substitute defoamers has become an important trend in the domestic defoamer market. In recent years, domestic research institutions and enterprises have increased their R&D investment, committed to developing products that can replace imported defoamers. These imported substitute defoamers have continuously improved in performance and quality, gradually meeting the needs of different industries for defoamers.

However, the development of imported substitute defoamers still faces many challenges. Firstly, imported defoamers have significant advantages in terms of raw material selection and process stability, while domestically produced defoamers still need to be continuously improved in terms of performance and quality. Especially in the field of high-end defoamers, such as polyether modified polysiloxane defoamers, the research and development capabilities of domestic enterprises still need to be strengthened.

Secondly, the competition in the domestic defoamer market is becoming increasingly fierce. Imported defoamers have a significant market share in the domestic market due to their brand and technological advantages. Domestic enterprises need to strengthen technological innovation and market expansion to enhance competitiveness. At the same time, the government should strengthen industry supervision and policy guidance to promote the healthy development of the domestic import substitution defoamer industry.

In the future, with the improvement of environmental awareness and the continuous advancement of technology, the research and development of imported substitute defoamers will pay more attention to environmental performance and sustainability. Biodegradable defoamers, water-based defoamers, and other green defoamers will become the focus of research and development. At the same time, the application of new catalysts, green solvents and other technologies will also promote the performance improvement and preparation efficiency of imported substitute defoamers.
