Hydroxypropyl methyl cellulose application range of a wide range of domestic substitution process accelerated.
In the global market, the hydroxypropyl methyl cellulose industry in Europe and the United States started earlier and developed for a long time. It has a large scale and a large number of strong production enterprises, including DOW Chemical Company and Hercules Company.
Hydroxypropyl methyl cellulose (HPMC) is also known as cellulose hydroxypropyl methyl ether, which belongs to non-ionic cellulose mixed ether, the appearance of white or white powder, soluble in water, soluble in the appropriate proportion of ethanol/water, propyl alcohol/water and trichloroethane and other solvents. Hydroxypropyl methyl cellulose has the characteristics of transparency, thickening, water retention, film formation, cohesiveness, dispersion, PH stability and so on, can be used as thickening agent, stabilizer, dispersant, film forming agent, emulsifier and so on.
Hydroxypropyl methyl cellulose production process mainly includes one - step etherification and step - by - step etherification. The one-step etherification method is applied earlier, which is the production mode of hydroxypropyl reaction and methylation reaction at the same time, and it is the production process which accounts for a relatively high proportion in industrial production. Stepwise etherification method is to carry out hydroxypropyl reaction and methylation reaction separately. Its industrial application time is short, but the product performance is better.
Hydroxypropyl methyl cellulose downstream applications in a wide range of fields. In the construction industry, hydroxypropyl methyl cellulose is mainly used as water retaining agent, retarder, binder; In the coating industry, mainly used as stabilizer, thickening agent, dispersant; In the petrochemical industry, mainly used as stabilizer, emulsifier, water retention agent; In the ink industry, mainly used as thickening agent, dispersant, stabilizer; In the synthetic resin industry, mainly used as release agent, softener, lubricant; In the pharmaceutical industry, mainly used as coating material, slow release agent, stabilizer, adhesive.
In the early stage of development, hydroxypropyl methylcellulose is mainly used in the construction industry and paint industry, with the continuous progress of production technology, its application field is constantly expanding, and gradually to food, medicine and other high value-added products. In the global market, the hydroxypropyl methyl cellulose industry in Europe and the United States started earlier and developed for a long time. It has a large scale and a large number of strong production enterprises, including DOW Chemical Company and Hercules Company.
According to the new thought world industry research center released the 2020-2024 China hydroxypropyl methyl cellulose industry market depth research and development trend prediction research report shows that compared with European and American countries, hydroxypropyl methyl cellulose industry in China starts late, many smaller enterprises, production equipment is relatively backward, the low level of technology, With the production of low-end products, the early market is mainly occupied by foreign enterprises. In order to realize import substitution, the research and development investment of hydroxypropyl methylcellulose industry in China increases constantly, leading enterprises improve technology level, and products already have high-end market competitiveness, and the domestic process of hydroxypropyl methylcellulose market is accelerated.
New industry analysts said that as the economy continues to grow, the quality of national life continues to improve, the Chinese market demand for hydroxypropyl methyl cellulose continues to increase. Since then, the market demand for hydroxypropyl methylcellulose in China is mainly concentrated in construction and coatings. With the development of downstream industry, food and medicine began to expand rapidly. In the future, the construction, food and medicine industries will be the important driving force to promote the growth of hydroxypropyl methyl cellulose market in China.
