Tungsten wire is suitable for heating elements of electrically heated glass windows due to its high temperature resistance and resistance effect. Its working principle is to embed ultra-fine tungsten wire into the glass interlayer, generate resistance heat by powering on, and evenly heat the glass surface, thereby achieving functions such as rapid defrosting, anti-fogging and temperature regulation. This technology can be applied to automobile windshields and rearview mirrors, aircraft windows and smart glass for buildings.
