The application range of epoxy resin insulating parts can generally be used at -60～100℃. The use of new resins, special curing agents and fillers can be used to formulate ultra-low temperature resistant adhesives (-196℃), high temperature resistant adhesives (350℃), conductive, and magnetic, Heat conduction, spot welding, strain, photosensitive, flame retardant, underwater glue and other special adhesives. Low toxicity, no physiological side effects, harmless to the human body, and can be formulated into environmentally friendly adhesives with low odor and non-toxicity. The toughness is not good, the brittleness is relatively large, and the toughening modification is usually carried out.

Due to its many unique advantages such as high insulation performance, high structural strength and good sealing performance, epoxy resin has been widely used in insulation and packaging of high and low voltage electrical appliances, motors and electronic components, and has developed rapidly. Mainly used for: pouring of electrical and motor insulation packaging. Manufacturing of integrally sealed insulating packages for high and low voltage electrical appliances such as electromagnets, contactor coils, mutual inductors, and dry-type transformers.

It has developed rapidly in the electrical industry. It has developed from normal pressure casting and vacuum casting to automatic pressure gel forming. It is widely used for potting insulation of devices equipped with electronic components and circuits. It has become an indispensable and important insulating material in the electronics industry. Electronic grade epoxy molding compound is used for plastic packaging of semiconductor components. Come to develop extremely fast.

Due to its superior performance, it has a tendency to replace traditional metal, ceramic and glass packaging. Epoxy laminated plastics are widely used in the fields of electronics and electrical appliances. Among them, the development of epoxy copper clad laminate is particularly rapid, and it has become one of the basic materials of the electronics industry. In addition, epoxy insulating coatings, insulating adhesives and electrical adhesives also have a large number of applications.
