Bisphenol A epoxy resin has a wide range of applications and the number of companies in my country continues to grow

Bisphenol A-type epoxy resin is a polymer compound refined by condensing bisphenol A and epichlorohydrin under alkaline conditions, washing with water, and removing solvent. Bisphenol A-type epoxy resin has the advantages of good heat resistance, excellent mechanical properties, and resistance to chemical corrosion. It is widely used in many fields such as petrochemical industry, aerospace, construction engineering, and automobile manufacturing.

Bisphenol A-type epoxy resin can usually be divided into two types: solid and liquid. Solid bisphenol A epoxy resin has a high average relative molecular weight and can be used to produce wind power composite materials, automotive primers, printed circuit boards, etc.; liquid bisphenol A epoxy resin refers to a liquid appearance at room temperature , bisphenol A-type epoxy resin with high fluidity and low viscosity, which can be used to produce coatings, electronic packaging materials, etc. With the growth of market demand for segmented products, the prosperity of the bisphenol A epoxy resin industry will further increase.

The preparation method of bisphenol A-type epoxy resin can be divided into one-step method and two-step method. The one-step method refers to using epichlorohydrin and bisphenol A as raw materials, and the finished product is obtained through a condensation polymerization reaction. This method has the advantages of simple operation process and short time consumption; the two-step method can be subdivided into two categories: catalytic polymerization method and bulk polymerization method. Catalytic polymerization is the mainstream preparation method. It refers to the phase reaction of epichlorohydrin and bisphenol A under the action of a catalyst, and the finished product is obtained through closed loop. This method has the advantages of high yield of finished product and good quality of finished product. my country Domestic bisphenol A-type epoxy resins such as E51 and E54 are produced using this method.

According to the “2023-2028 China Bisphenol A Epoxy Resin Industry Market In-depth Research and Development Prospects Forecast Report》shows that bisphenol A-type epoxy resin is widely used in many fields such as petrochemical industry, aerospace, construction engineering, and automobile manufacturing. In the petrochemical industry, bisphenol A epoxy resin can be used to produce adhesives; in the aerospace field, bisphenol A epoxy resin can be used to produce aircraft coatings and structural parts; in the construction engineering field, it can be used to produce coatings; In the field of automobile manufacturing, it can be used to produce automobile braking systems, engines and bodies, etc.

Bisphenol A-type epoxy resin is the most widely used epoxy resin in the world. Attracted by market prospects, the number of companies in this industry in my country continues to grow. Luxi Chemical Group Co., Ltd., Blue Star Chemical New Materials Co., Ltd., Wuxi Akoli Chemical Co., Ltd., Jinan Shengquan Group Co., Ltd., etc. are the main manufacturers of bisphenol A epoxy resin in my country.

Industry analysts said that bisphenol A-type epoxy resin has excellent performance and is widely used in many fields. It will be gradually released in the future with downstream demand. , the industry development speed will further accelerate. In recent years, with the continuous improvement of independent research and development capabilities of local enterprises, the prosperity of my country’s bisphenol A-type epoxy resin industry has continued to improve, and the quality of domestic products has occupied a competitive advantage in the global market.
