With the rapid development of domestic industry, the demand for defoamers is also increasing day by day. However, for a long time, the domestic high-end defoamer market has been mainly dominated by foreign brands, and there is a certain gap between domestic enterprises in technology research and development and market competitiveness. In order to break this situation, although significant progress has been made in the research and development of imported substitute defoamers in China in recent years, it still faces many challenges.

In recent years, domestic enterprises have made significant breakthroughs in the research and development of defoamer technology. Through continuous technological innovation and process improvement, domestic enterprises have successfully developed various high-performance imported substitute defoamers, such as organosilicon defoamers, polyether defoamers, etc. These products have approached or reached the international advanced level in terms of performance, and can meet the needs of different industries. With the improvement of the performance of imported defoamers and the reasonable positioning of prices, their market share in the domestic market is gradually expanding. Especially in some fields that require high performance of defoamers, such as pharmaceuticals, food processing, papermaking, etc., domestic imported substitute defoamers have achieved a certain market share. The research and development of domestic imported substitute defoamers has also driven the development of related industrial chains. From raw material supply, production and processing to market sales, a relatively complete import substitution defoamer industry chain has been formed in China. This will help improve the market competitiveness of domestic enterprises and promote the further development of imported substitute defoamers.

Although significant progress has been made in replacing defoamers with imported ones domestically, there are still certain technical barriers compared to foreign brands. Especially in the high-end market, foreign brands still dominate with their advanced technology and brand influence.

With the continuous expansion of the domestic market for imported substitute defoamers, market competition is becoming increasingly fierce. Domestic enterprises need to continuously improve production efficiency and service levels while ensuring product quality to cope with fierce market competition. With the increasingly strict environmental regulations, the research and production of imported substitute defoamers in China are also facing enormous environmental pressure. Enterprises need to increase investment in environmental protection and adopt more environmentally friendly production processes and raw materials to meet environmental requirements.
