The silicone emulsion industry has high barriers and the production technology level of local enterprises needs to be improved.

Silicone emulsion, referred to as silicone emulsion, refers to an emulsion composed of oil-in-water silicone oil, water and surfactants. Depending on the surface chemicals used, silicone emulsions can be divided into anionic, cationic, nonionic silicone emulsions, etc. Silicone emulsion is one of the important silicone products. It has good heat resistance, hydrophobicity, compatibility, film-forming properties, oxidation resistance and other properties. It is widely used in industry. The main application fields include textile, papermaking, Electronics, chemical industry, construction, leather, medicine, cosmetics, waterproof materials, etc.

Silicone emulsion is mainly prepared by mechanical emulsification method, suspension polymerization method, phase inversion emulsification method, phase inversion temperature emulsification method, etc. Among them, the suspension polymerization method is currently the main method for the production of silicone emulsion at home and abroad. The process flow refers to emulsifying the silicone oligomer first, and then adding the emulsion to a medium containing a catalyst at the polymerization temperature for polymerization to generate a silicone emulsion. process.

However, the current production of silicone emulsion through suspension polymerization has the disadvantage of long reaction time, which seriously affects its industrial development. Therefore, the production method of silicone emulsion needs to be continuously optimized and upgraded, and the key technical barriers are relatively high. At the same time, the production of silicone emulsion requires sufficient shear force to form a stable water-based continuous emulsion. It needs to be equipped with a variety of high-shear equipment such as tank mixers, dual planetary mixers, and high-pressure homogenizers, and the funds required for production are The investment is large.

According to the “China Silicone Emulsion Industry Market Monitoring and Future Development Prospects Research Report 2023-2027” released by the Industrial Research Center , the current silicone emulsion has high technical and financial barriers, and the industry entry threshold is high. The global market is mainly dominated by international leading companies with a long development time and sufficient technical experience reserves. The main companies include Elkem of Norway and Malaysia. Biolab International, Applied Materials of the United States, Shin-Etsu of Japan, Incai of the Netherlands, Wacker Chemical of Germany, etc. my country’s silicone emulsion industry started late, with a small number of companies in this field and a low market share. The main companies include Fluoropolymer Chemicals, Blue Star Silicone, Tuoli Technology, etc. In the future, local companies will need to increase their efforts. Technical research efforts.

Industry analysts said that silicone emulsion is one of the important segmented products of silicone materials, which can be used as defoaming agent, Release agents, lubricants, polishes, cleaners, etc. are used in many fields such as papermaking, chemical industry, and automobiles, and have a wide range of applications. Silicone emulsion is a technology- and capital-intensive industry. At present, the global market is still dominated by leading international companies. Key technologies of local companies have yet to be broken through. In the future, R&D and innovation will continue to be increased, and the industry has huge room for growth.
