A new topic for the future development of polymer insulation materials is to further improve the heat resistance of materials, develop new materials with F-class, H-class and higher heat resistance; develop ultra-low temperature insulation materials for superconductivity; and develop insulation materials with excellent water resistance. And radiation-resistant, freon-resistant insulation materials; develop high-frequency dielectric materials with high temperature resistance and good processing performance, and develop insulation materials with other special properties (such as heat conduction, high purity, photosensitive, etc.).
