Zhejiang Jingtai Glass Technology Co., Ltd.: Electro-Heated Glass Technology Leads to a New Era of Clear Vision

Zhejiang Jingtai Glass Technology Co., Ltd., a company deeply rooted in the field of specialty glass, has recently made significant progress in the research and development of electro-heated glass. As a national high-tech enterprise, the company, with its advanced production processes and strict quality control system, is committed to providing professional window defogging and defrosting solutions for various harsh environments, marking a further improvement in the company's layout in the field of functional specialty glass.

## Technical Principle: Intelligent Heating Reshapes the Visual Experience

Electrically heated glass, also known as electrothermal glass, is a laminated glass product that heats up when electricity is applied. Its core working principle is based on the generation of heat by current passing through a high-resistance element: extremely fine tungsten or constantan wires are embedded on one side of the interlayer of the laminated glass, or a transparent conductive film is coated on the inner surface of the glass, allowing the glass to be heated evenly when electricity is applied.

The electro-heated glass developed and produced by Jingtai Glass uses high-quality automotive-grade float glass as the base material, and is precisely bonded together with two or more pieces of tempered glass using PVB or special films. The heating element is fully embedded within the interlayer, ensuring excellent light transmittance while avoiding the risk of external contact. The glass itself possesses thermistor properties, allowing for intelligent connection to a temperature control system to automatically adjust the glass surface temperature. The maximum temperature can reach 40-60℃, and the wide voltage range meets the needs of various application scenarios.

## Superior Performance: A Technological Achievement of Multifunctional Integration

Jingtai Glass's electrically heated products, with their outstanding performance characteristics, have become the ideal choice for many special environments:

**Frost Removal Function**: After being powered on, the glass surface temperature rises to 35-40℃, remaining above the air dew point, effectively preventing frost, condensation, and ice formation on the glass surface. This feature ensures that the glass surface remains frost-free even under harsh conditions such as an ambient temperature of 25℃, humidity of 75%, and a freezer temperature of -20℃.

**Excellent Optical Performance:** Utilizing conductive wires or films as the heating medium, the product boasts approximately 80% light transmittance, ensuring excellent light transmission and distortion prevention. This allows observers to see clearly, realistically, and with high resolution.

**UV Radiation Protection:** The glass possesses highly efficient UV absorption capabilities, effectively blocking UV rays from entering indoor spaces or cockpits, reducing health hazards to personnel and facilities.

**Superior Safety Performance:** Employing a sandwich structure composed of organic and inorganic materials, the product maintains its integrity even after breakage, preventing shards from flying or penetrating, providing exceptional safety.

## Diverse Applications: From Extreme Cold Sentry Posts to Freezing Windows

With its powerful defogging and defrosting performance and reliable safety features, Jingtai Glass's electrically heated products can be widely used in various special environments requiring protection against condensation and icing:

**Transportation Sector:** Locomotive windshields, aircraft windows, ship cockpit observation windows, and automotive windshields, providing drivers with a clear view and ensuring driving safety.

**Industrial Equipment:** Cold storage observation windows, low-temperature test chamber windows, environmental test chambers, high and low temperature shock chambers, constant temperature and humidity chambers, and other refrigeration and freezing equipment.

**Security Facilities:** Border guard post observation windows, bank safe anti-fog windows, etc.

**Civilian and Commercial:** Doors and windows for buildings in extremely cold regions, display cabinets, freezer/refrigerator display windows, sunroom defogging and snow removal equipment, etc.

## Quality Assurance: Rigorous Processes Create Reliable Products

Behind the high-quality electrically heated glass is Jingtai Glass's relentless pursuit of excellence in production processes. The production process of electrically heated glass is similar to that of laminated glass, and the company strictly controls every step:

**Clean Environment Control:** Impurities in the product are a major cause of quality issues. The company uses high-quality PVB film and maintains a clean environment during the lamination process to prevent lint and airborne dust from contaminating the finished product.

**Strict Inspection of Raw Glass Sheets:** Strict inspection of raw glass sheets is conducted. Scratched glass is not allowed to proceed to the next process to prevent intentional scratching.

**Prevention of Delamination Issues:** Strict control of environmental humidity, glass surface cleanliness, interlayer material cleanliness, and autoclaving temperature effectively prevents lamination of the laminated glass.

**Product Inspection Before Delivery:** Each completed product undergoes a 48-hour frequent temperature-increasing test to ensure stable and reliable product performance.

## Future Outlook: Adapting to Standard Upgrades and Expanding the Market

With the continued development of downstream industries such as automotive and aviation, the demand for electrically heated glass in my country is increasingly significant. In May 2025, the State Administration for Market Regulation and the Standardization Administration of China released two industry standards: *Environmental Test Methods for Electrically Heated Aviation Glass (GB/T45664-2025)* and *Electrically Heated Aviation Glass (GB/T45825-2025)*, both officially implemented on December 1, 2025. Under the favorable environment of gradually improving industry standards, the high-quality development of my country's electrically heated glass market is further accelerating.

Zhejiang Jingtai Glass Technology Co., Ltd. will continue to uphold the development philosophy of "innovation, quality, and safety," keep pace with industry standard upgrades, increase R&D investment, and continuously optimize the performance of its electrically heated glass products. Relying on its profound technological accumulation and rigorous quality system, the company will provide customers in various fields such as aviation, automotive, shipbuilding, and refrigeration with superior electrically heated glass solutions, safeguarding clear vision with technological strength and contributing "Jingtai" power to the high-quality development of the specialty glass industry.
