Problems solved by technology

However, when the circuit board is used in an acid-base medium, in addition to the conventional performance of polyurethane, it is also required to have high corrosion resistance, but ordinary polyurethane materials have poor corrosion resistance, which severely limits the use of polyurethane circuit boards. service life and safety in use; in addition, with the development of miniaturization and intelligence of electronic appliances, higher requirements are put forward for the heat resistance of the circuit board materials used. The heat resistance of the existing polyurethane materials is not very good. Ideal, which further limits the application of polyurethane materials in circuit boards
