Mica shaped processing parts are made of high-quality mica plates as raw materials to produce various mica pads, mica flanges and mica stamping parts. Mica sheet in new energy vehicles is characterized by high temperature resistance, insulation performance, light material, high cost performance, easy assembly and other characteristics. It is widely used in battery module, battery pack cover plate, temperature monitoring, line protection and other aspects of new energy vehicles. When special circumstances occur in the vehicle, it can effectively delay or prevent the heat diffusion caused by battery explosion, and plays a vital role in protecting the life safety of vehicles and personnel.
