Battery Thermal Runaway Protect Mica sheet winding insulation mica materials
Mica sheet is a high temp insulating material made of quality mica materials and high-performance organic silicon resin after the melting and laminating process, widely used in electrical appliances such as toasters, hair dryers and warm air blowers, etc and other electric heaters which require high temp electro insulation.
