The excellent physical, mechanical, and electrical insulation properties, adhesive properties with various materials, as well as the flexibility of its usage process of epoxy resin are not possessed by other thermosetting plastics. Therefore, it can be made into coatings, composite materials, casting materials, adhesives, molding materials, and injection molding materials, and is widely used in various fields of the national economy.
Due to its unique advantages such as high insulation performance, strong structural strength, and good sealing performance, epoxy resin has been widely used in the insulation and packaging of high and low voltage electrical appliances, motors, and electronic components, and has developed rapidly. Mainly used for casting insulation packaging components for electrical appliances and motors. Manufacturing of overall fully sealed insulation packaging components for high and low voltage electrical appliances such as electromagnets, contactor coils, transformers, and dry-type transformers. It has achieved rapid development in the electrical industry. From normal pressure pouring and vacuum pouring, automatic pressure gel forming has been developed.
