In the electrical and electronic industry, polymers are mainly used as materials for insulation, shielding, conduction, and magnetic conduction. In the field of communication, the demand for polymer materials has been widely used in various types of terminal equipment, as well as the development of society. Production of high-performance materials such as optical fibers and optical discs. China's electric power producing countries, the industry's demand for polymer materials is relatively large. The polymer material is light, insulating, corrosion-resistant, high in surface quality and easy to shape and process. This is the best material for producing various household appliances, and household appliances are the essential daily necessities for people, and the development of polymer materials electrical industry. It won't stop.
