Vacuum pressure impregnation (VPI) resin is mainly used in the motor field. Bofei Electronics is a leading company in the domestic industry.

VPI resin, vacuum pressure impregnation resin, refers to a resin formulated from epoxy-modified heat-resistant unsaturated polyester resin, special curing agent, reactive diluent and other materials. VPI resin has excellent insulation, heat resistance, dielectric properties, chemical stability, impregnation processability and other characteristics. It can be widely used in optical modules, high-voltage motors, wind power motors, communications and other fields, and the market demand is huge.

VPI resin can be widely used in motor insulation scenarios due to its excellent properties. Against the background of the steady rise in prosperity of the domestic machinery manufacturing industry, the replacement speed of high-voltage motors and engines continues to accelerate, and the power density continues to increase, which in turn prompts the continuous upgrading of motor insulation material requirements. Traditional insulation materials can no longer meet the current requirements for continuous upgrading of motor insulation materials. As a result, the advantages of VPI resin with high thermal conductivity, high insulation, and high heat resistance have gradually emerged and are widely favored by the market.

According to the “2023-2028 Vacuum Pressure Impregnation (VPI) Resin Industry Market In-depth Research and Investment Prospects Forecast Analysis Report” released by the Industrial Research Center shows that at the same time, in the field of wind power motors, VPI resin also has broad market development space. Wind turbines are the core components of wind power towers. In order to ensure the continuous and stable operation of wind power towers, wind turbines have higher requirements for the insulation materials required for the stator and rotor. Therefore, VPI resin has gradually become popular due to its excellent environmental protection and insulation properties. Becoming the mainstream insulation material in the wind turbine market. As domestic wind power installed capacity continues to increase, the demand for VPI resin continues to increase.

VPI resin is a type of high-end insulation material, which is difficult to produce and has high technical barriers. For a long time, its production technology has been monopolized by international companies, and the level of localization is low. International VPI resin companies mainly include Germany’s Allentas, Germany’s SynFlex, Germany’s Allnex, Austria’s Constantia, the United States’ Axalta, and Switzerland’s VonRoll.

However, in recent years, as local companies have gradually conquered a number of key technologies, the process of domestic substitution in my country’s VPI resin market has continued to accelerate. Currently, the main companies entering the VPI resin market in my country include Suzhou Jufeng Electrical Insulation System Co., Ltd., Zhejiang Rongtai Technology Enterprise, Zhejiang Bofei Electric Co., Ltd., etc.

Industry analysts said that Bophi Electronics is the leading company in my country’s VPI resin industry and the company focuses on electrical The research and development, production and sales of polymer composite materials such as insulation materials. At present, high-quality environmentally friendly VPI resin products such as environmentally friendly wind power VPI impregnating paint and wind power VPI impregnating paint have been widely used in the wind power field and have partially replaced imported products. . In the future, as the technology of local enterprises continues to improve, the process of domestic substitution of VPI resin in my country is expected to continue to accelerate, and the industry has broad prospects for development.
