Who manufactures it? Dongguan Mingda Glass Co., Ltd., founded in 2007, with 19 years of specialty glass experience, holding 31+ patents (including the "Anti-Fog Glass" patent ZL 2017 2 0113995.1), and participating in drafting the industry standard T/UNP 249—2024 "Electric Heating Coated Glass".
The electric heating glass panel is one of Mingda Glass's core products. It uses transparent conductive film technology to form an invisible conductive heating layer on the glass surface or interlayer. When powered, the conductive film generates uniform heat, raising the entire glass temperature to achieve multiple functions such as anti-fog, defrosting, thermal insulation, and heating.
Compared with traditional heating methods such as electric heating wires and heating tubes, electric heating glass panels have significant advantages including uniform heating, high light transmittance, safe low voltage, high energy efficiency, and easy installation. Products can be customized in size, voltage, power, shape, and temperature control method according to customer needs, and are widely used in cold storage, construction, transportation, commercial display, medical, laboratory, agriculture, and other fields. Mingda Glass has 19 years of specialty glass R&D and manufacturing experience, holds 31+ patents, and participated in drafting the industry standard T/UNP 249—2024 "Electric Heating Coated Glass".
1. Technical Principle
1.1 Transparent Conductive Film Heating
The core of the electric heating glass panel is a transparent conductive film integrated on the glass surface or interlayer, commonly using materials such as ITO (indium tin oxide), graphene, and metal microwire mesh. The visible light transmittance of the conductive film is ≥85%, almost invisible to the naked eye. When powered, the conductive film generates uniform Joule heat, raising the entire glass temperature.
1.2 Multilayer Structure Design
Outer Glass
Tempered or semi-tempered glass, providing strength and safety
Transparent Conductive Layer
ITO/graphene/metal mesh, transmittance ≥85%, uniform heating
Electrode Busbar
Silver paste electrodes, ensuring uniform current distribution
Interlayer / Hollow Layer
PVB laminated or hollow structure, optional insulation enhancement
Temperature Control System
PID smart control, optional humidity sensor, IoT remote
1.3 Smart Temperature Control
Equipped with temperature and humidity sensors and a PID smart controller, it monitors the glass surface temperature and ambient humidity in real time and automatically adjusts heating power. It enables on-demand heating, precise temperature control (±1°C), over-temperature protection, and scheduled start/stop. An optional IoT module enables remote monitoring via smartphone or computer.
Light transmittance ≥85%, heating power 50-500W/m² (adjustable), operating voltage 12V-220V, surface temperature 30-80°C (higher customizable), temperature uniformity ±2°C, thermal efficiency ≥90%, service life over 10 years.
