Polyoxypropylene glycol (PPG) has a wide range of application fields, and most of the global production capacity is concentrated in the Asia-Pacific region.

Polyoxypropylene glycol (PPG), also known as polypropylene glycol, is a mixture of starter propylene glycol and catalyst (potassium hydroxide) added to the kettle for preparing the catalyst. After a series of processes, propylene oxide is added to make the ring Propylene oxide is continuously polymerized and reaches a certain molecular weight. After steaming out the remaining propylene oxide, the polyether mixture is transferred to the neutralization kettle, and then the product is obtained through neutralization, filtration, refining and other processes. Polyoxypropylene glycol is a type of polyether polyol. As a chemical product, polyoxypropylene can be used to produce polyurethane adhesives, elastomers, sealants, lubricants, waterproof materials and other applications in automobiles, medicine, construction, cosmetics, etc. and other fields.

Polypropylene oxide is produced through the ring-opening polymerization of propylene oxide and is a soft foam polyether. Under normal circumstances, polyoxypropylene glycol appears as a clear colorless or light yellow transparent oily liquid, which is soluble in most organic solvents such as toluene, ethanol, and acetone. Polyoxypropylene glycol with a higher molecular weight is insoluble in water. Polyoxypropylene glycol is a type of polyether polyol. It has good water resistance, flexibility, and low cost. Therefore, polyoxypropylene glycol has become a commonly used oligomer polyol in the development of water-based polyurethane in my country. Alcohol raw materials.

According to the “2021-2025 China Polyoxypropylene Glycol (PPG) Industry Market Monitoring and Future Development Prospects Research Report” shows that in 2020, the global polyoxypropylene glycol market size will be around 10.8 billion yuan. Globally, the polyoxypropylene glycol market is mainly concentrated in Asia-Pacific, North America and Europe, among which the Asia-Pacific region is the largest in the world. The polyoxypropylene glycol production and consumption market accounts for nearly 60% of the total consumption.

In the international market, the main suppliers of polyoxypropylene glycol include Germany’s BASF, KKPC, Dow Chemical, Japan’s Asahi Glass Co., Ltd. and Mitsui Group Chemicals. With their technology, brand and quality advantages, leading companies occupy the leading position in polyoxypropylene glycol. Major market share. Polyoxypropylene glycol is a secondary processing product of propylene oxide. my country is a major producer of propylene oxide. There are many domestic companies with polyoxypropylene glycol production capabilities, including Shandong Blue Star Dongda Chemical and Shanghai Gaoqiao Petroleum. Chemical industry, Hebei Yadong Chemical Group, Jiangsu Luyuan New Materials, Jiangsu Zhongshan Chemical, Hangzhou Dianhua Group Auxiliary Chemical, Jiangsu Haian Petrochemical, Tianjin Dagu Fine Chemical and many other companies.

Industry analysts said that polyoxypropylene glycol has good water resistance, flexibility, low cost and price, and it can be used It produces polyurethane adhesives, elastomers, sealants and other products, with downstream applications involving automobiles, construction, medicine and other fields. my country is the world’s largest chemical country. There are many domestic companies with polyoxypropylene glycol production capacity. However, due to technical and process limitations, in the international market competition, foreign leading companies still occupy the majority of the high-end polyoxypropylene glycol market. share.
