How to break the dependence on imported domestic defoamers?

Against the backdrop of global supply chain restructuring, the import substitution of domestically produced defoamers has become a focus of the industry. Although domestic enterprises have achieved phased results, how to move from "substitution" to "transcendence" still requires efforts from multiple dimensions such as technology, industrial chain, and market.

The first thing worth paying attention to is the current technological research and development progress of domestic defoamers. Domestic enterprises have improved their emulsification technology and compounding processes to enhance the foam inhibition durability of their products. Some organic silicon defoamer products have been used in the coatings and ink industries. In response to environmental protection needs, some companies have developed biodegradable defoamers using vegetable oil as raw material, filling the domestic gap. At the same time, the stability of defoamers in high-temperature and high-pressure environments has been improved through nanomaterial modification.

Secondly, there is the problem of insufficient collaboration in the industrial chain. Due to limitations in raw materials, outdated formulation processes, and insufficient research and development investment, the localization rate of core raw material industries is low, and some still need to be imported. Therefore, domestic defoamer companies should collaborate with raw material companies to reduce supply chain costs. In addition, in terms of market education, enterprises can collaborate with universities and research institutes to tackle the synthesis technology of key raw materials, and gradually replace imported products through domestic independent research and development of organic silicon defoamers.

Import substitution is not only a technical issue, but also a reconstruction of the industrial chain ecology. In the future, domestic defoamer companies need to continue investing in technological innovation, supply chain integration, and market education in order to truly achieve the transformation from "following" to "leading".
