Bisphenol S (BPS) is an important substitute for bisphenol A and its application fields are constantly expanding.

Bisphenol S, also known as 4,4′-dihydroxydiphenylsulfone, or BPS for short, is a chemical substance with the molecular formula C12H10O4S. It appears as white needle-like crystals and is easily soluble in aliphatic hydrocarbons and soluble in ethanol and isopropyl alcohol. , acetonitrile, acetone, etc., insoluble in toluene and water. Bisphenol S is an important chemical raw material that can be widely used in dyes, leather, pesticides and other fields.

Bisphenol S is a close molecular analog of bisphenol A (BPA). The two are relatively similar in properties and uses. Bisphenol A is an organic compound with two hydroxyphenyl groups. It is mainly used as a raw material for the synthesis of polymer materials such as epoxy resin, polycarbonate, and polysulfone resin. It can also be used as a plasticizer, stabilizer, and barrier agent. The use of fuels and terminal applications include daily necessities, food packaging, rubber, etc. However, in recent years, as relevant research has deepened, bisphenol A has been found to be seriously harmful to children’s physical development. Therefore, plastic baby bottles, food packaging and other products containing bisphenol A have been banned in China, the United States, Canada and other countries. Use and sale.

Bisphenol S is an important substitute for bisphenol A. It has excellent heat resistance, light resistance, and oxidation resistance. It can be used in daily utensil manufacturing scenarios where the use of BPA is prohibited or restricted, such as food packaging and plastic food cans. Lining etc. In addition, bisphenol S has a wide range of uses, such as being used as a raw material in the manufacturing of polymer materials such as polycarbonate, epoxy resin, polyester, phenolic resin, and as a leather kneading agent in the leather manufacturing process. It is used as a dispersing agent in dye manufacturing and as a fixing agent in the textile field.

According to the“Bisphenol S (BPS) Industry Market In-depth Research and Investment Prospects Forecast Analysis Report 2023-2028” released by the Industrial Research Center It shows that with the continuous expansion of application fields, the current global bisphenol S market demand is continuing to increase and the scale is expanding. The global bisphenol S market size will be approximately US$750 million in 2022, a year-on-year growth of approximately 13%.

Globally, the major companies in the field of bisphenol S production include Japan’s Konishi Chemical, Japan’s Soda Daily Chemicals, Germany’s BASF and other international companies, as well as Jiangyin Changsheng Chemical, Jiangyin Wenjun Chemical, Haining Huangshan Chemical, Yunan Xinhao Chemical New Materials, Chinese companies such as Yancheng Huada New Materials, Pingdingshan Runze Chemical, Lianyungang Newtech Chemical, etc.

Industry analysts said that bisphenol S is an important organic chemical raw material and can be widely used in In the fields of medicine, plastics, dyes, etc., there is broad market development space. At the same time, because bisphenol S has similar properties to bisphenol A, as the hazards of bisphenol A gradually become more apparent, bisphenol S has become a key alternative material. Its application fields have continued to expand, and market demand has continued to increase. From the perspective of domestic production, the number of enterprises with bisphenol S production capacity in my country is currently relatively small, and most of them are small and medium-sized enterprises. There is still considerable room for growth in the industry in the future.
