In today's highly competitive manufacturing industry, a technology that utilizes the synergistic effect of vacuum and pressure is quietly enhancing the reliability and performance of products across various sectors. This technology is vacuum pressure impregnation technology.
Vacuum pressure impregnation technology is an advanced process that uses vacuum technology and applies pressure to fill liquid impregnation liquid into the micro-pore defects of the workpiece. After curing, it forms a solid whole with the workpiece, thereby sealing the micro-pores.
This technology, through the synergistic effect of vacuum and pressure, can effectively solve the porosity problem inside materials, enhance the sealing performance, insulation and mechanical strength of products, and has become an indispensable manufacturing process in many industries.
Vacuum pressure impregnated transformers are important applications in the electrical and electronic industry. According to market research reports, the market size of vacuum pressure impregnated transformers in China has reached hundreds of millions of yuan, and the global market size has also reached a considerable scale. It is expected that the global market size of vacuum pressure impregnated transformers will reach a new height.
Vacuum pressure impregnated resin, as a high-end insulating material, plays a crucial role in this field. It refers to a resin formulated from materials such as epoxy-modified heat-resistant unsaturated polyester resin, special curing agents, and reactive diluents.
VPI resin features excellent insulation, heat resistance, dielectric properties, chemical stability and other characteristics, and can be widely used in optical modules, high-voltage motors, wind power motors, communications and other fields.
Traditional insulating materials can no longer meet the continuous upgrading requirements of motor insulating materials at present. The advantages of VPI resin, which features high thermal conductivity, high insulation and high heat resistance, are gradually emerging and widely favored by the market.
