Flame retardant epoxy resin has excellent performance and broad application prospects

Flame retardant epoxy resin, also known as self-extinguishing epoxy resin, refers to epoxy resin containing flame retardant groups or mixed with flame retardants. Flame-retardant epoxy resin has the advantages of high temperature resistance, good electrical insulation properties, good water resistance, and good flame retardancy. It is widely used in electronic and electrical, photovoltaic power generation, chemical industry and other fields. According to different preparation methods, flame retardant epoxy resin can be divided into two categories: additive flame retardant epoxy resin and reactive flame retardant epoxy resin.

Added flame retardant epoxy resin usually blends the flame retardant directly with the epoxy resin to improve the flame retardancy of the epoxy resin. Additive flame retardant epoxy resin has the advantages of low production cost and convenient operation, but there is no chemical reaction during the preparation process, so it has poor mechanical properties and low flame retardant efficiency. Reactive flame-retardant epoxy resin is made from halogen- and phosphorus-containing monomers and has excellent flame-retardant effects. It is expected to become a mainstream product in the flame-retardant epoxy resin market in the future.

Epoxy resin is the main raw material of flame retardant epoxy resin. Epoxy resin refers to a polymer containing more than two epoxy groups in the molecule. It is widely used in coatings, electronic and electrical, building materials and other fields. As the severe situation of the COVID-19 epidemic gradually comes under control, my country’s epoxy resin production has increased. In 2022, my country’s epoxy resin output will reach 1.496 million tons, a year-on-year increase of 9.1%. Benefiting from the sufficient supply of raw materials and the mature production technology of local enterprises, the development speed of my country’s flame retardant epoxy resin industry will further accelerate.

According to the “2023-2028 China Flame Retardant Epoxy Resin Industry Market In-depth Research and Development Prospects Forecast Report released by the Industrial Research Center It shows that flame retardant epoxy resin can be used in electronic and electrical, photovoltaic power generation, chemical industry and other fields. In the electronic and electrical field, flame-retardant epoxy resin can be used to produce semiconductor packaging materials, flame-retardant copper-clad laminates, etc.; in the field of photovoltaic power generation, flame-retardant epoxy resin can be used to produce special glue for solar cell backsheets. As downstream demand continues to grow, the market size of flame-retardant epoxy resin will expand.

The main manufacturers of flame-retardant epoxy resin in my country include Hongchang Electronic Materials Co., Ltd., Hunan Baili Engineering Technology Co., Ltd., Yangzhou Chenhua New Materials Co., Ltd., etc. Hongchang Electronics is my country’s leading flame-retardant epoxy resin company. In recent years, the company has focused on the development of green and environmentally friendly flame-retardant epoxy resin. According to the company’s annual report, the company achieved revenue of 4.45 billion yuan in 2021, a year-on-year increase of 77.8%.

Industry analysts said that flame-retardant epoxy resin has excellent performance and has broad application prospects in many fields. With the gradual release of market demand, The development trend of the industry will continue to improve. The sufficient supply of raw materials and the improvement of technical level have laid a good foundation for the development of my country’s flame retardant epoxy resin industry. It is expected that in the future, companies with green and environmentally friendly flame-retardant epoxy resin production capabilities will occupy a larger space in the market.
