Smart glass is a new type of functional product that combines electronic technology with glass technology. It involves adhering a new type of liquid crystal material to basic materials such as glass and films, and then using circuitry and control technology to create an intelligent glass product. With the rapid development of fields like smart buildings and smart homes, the demand for smart glass is increasingly growing. Our company's self-developed EVA inter intermediate film for smart glass boasts ultra-high transparency, ultra-low haze, excellent dimensional stability, and resistance to environmental aging. It can be widely applied in high-end construction, smart homes, display cases, automotive glass, and other fields, providing innovative solutions for smart glass. Choosing our EVA intermediate film maximizes value.

Product Features

Strong Weather Resistance

Our TPU film also possesses exceptional weather resistance. From the scorching ground temperatures at hot desert airports to the extreme cold of minus dozens of degrees Celsius in the stratosphere, from the corrosive high humidity and salt spray during transoceanic flights to the intense UV radiation on polar routes, the molecular structure of Sheng ding's TPU protective film is specially designed to withstand high temperatures without softening, deforming, or causing adhesion failure, and to resist cracking at low temperatures that could affect optical performance. It consistently maintains material stability, providing solid protection for aviation glass. This ensures that the aircraft glass remains unscathed after long exposure to harsh environmental conditions, with its protective effectiveness undiminished.

High Transparency

This TPU protective film features high transparency, with a light transmission rate of over 90%, possessing the pure optical-grade characteristics. When installed on aircraft glass, such as airplane side windows, cockpit canopies, windshields, and other transparent components, it offers a clear view. It allows pilots to see as if looking directly into the sky with the naked eye, with the contours of clouds and details of landmarks clearly visible. Whether it's for ordinary cloud observation or for precise judgment of runway conditions during landing, the view is unobstructed without glare or ghosting to interfere with the pilot's line of sight, ensuring accurate and error-free flight operations.

Exceptional Adhesive Characteristics

The outstanding adhesive characteristics of our product are like an invisible super glue, firmly anchoring itself to the aerospace glass. Even under the intense vibrations during high-speed flight and frequent changes in air pressure, it ensures seamless bonding, without layering or separation. In the event of bird strikes or impacts from debris carried by air currents, which may damage the outer layer of glass, our thermoplastic polyurethane (TPU) film can restrain the fragments with its strong adhesive force, preventing them from spraying into the cabin and endangering personnel safety. It forms the last line of defense for aviation safety.

Exceptional Transparency and Haze Characteristics

This EVA intermediate is specifically designed for smart glass and other glass applications that require extremely high transparency, such as jewelry display counters, banks, photovoltaic solar panels, and more. It boasts ultrahigh transparency and ultra-low haze, offering strong work ability and ensuring that the smart glass provides a crystal-clear visual effect when switching between transparent and opaque states. Whether it's used in architectural glass curtain walls or partition decorations, its outstanding performance brings an unparalleled visual experience to users.

Wide Processing Adaptability

In terms of processing, Sheng ding EVA inter layer film has strong adaptability. It can be easily processed in both glass laminating furnaces and autoclaves, meeting various production needs. Thanks to its special technical formulation, the material's stability is extremely high, preventing glue overflow during the processing, which eliminates the cumbersome step of secondary cleaning required by traditional film processing, thus significantly increasing production efficiency.

Stable adhesion characteristics

Our EVA film for switchable glass has a strong adhesive force with the switchable film, ensuring a tight and seamless connection between the two. Additionally, its good dimensional stability maintains precise fitting without deformation or distortion under various complex environmental conditions such as high temperature, humidity, or cold. The excellent environmental aging resistance ensures that during long-term use, the adhesion strength and clarity of the film remain stable and unchanged. Even after extended periods, the switchable glass maintains its original appearance.
