What are the classifications of defoaming agents and which manufacturers produce them?

Surfactant-based defoaming agents are a class of surfactants that reduce liquid surface tension to suppress bubble formation and stability. Common types include nonionic, anionic, and cationic surfactant defoamers. 5) Biological Defoaming Agents: These agents primarily utilize substances derived from microbial fermentation—such as enzymes, microbial cells, and fermentation broths. They exhibit excellent biodegradability and environmental compatibility, and are widely applied in certain specialized fields. Selection of an appropriate defoaming agent must consider specific application requirements and process conditions, while strictly adhering to relevant safety protocols and environmental protection regulations. Major foreign defoaming agent manufacturers: 1. Dow Chemical Company: A global leader in chemical manufacturing, offering diverse defoaming agents and surfactants. 2. BASF SE: One of the world’s largest chemical companies, providing a broad portfolio of defoaming agents—including organic and mineral oil-based types. 3. Evonik Industries AG: A German chemical company supplying various defoaming agents, including polymer- and surfactant-based formulations. 4. Momentive Performance Materials Inc.: A global leader in specialty chemicals, offering a wide range of defoaming agents and surfactants. 5. Shin-Etsu Chemical Co., Ltd.: A Japanese chemical company providing multiple defoaming agent types—including organic and polymer-based variants. 6. Air Products and Chemicals, Inc.: A U.S.-based chemical manufacturer supplying diverse defoaming agents and surfactants. Major domestic defoaming agent manufacturers: 1. Three Gorges Chemical Group Co., Ltd.: Operates multiple subsidiaries dedicated to R&D, production, and sales of defoaming agents. 2. AkzoNobel (China) Investment Co., Ltd.: As a global leader in chemicals, supplies various defoaming agents in the Chinese market. 3.
