Optical-grade TPU film, polyurethane TPU inter layer film being used in aerospace vehicle transparent components TPU film material professional manufacturer

The carefully crafted TPU protective film by Sheng ding is specifically designed for the sandwich glass process. It is used between two layers of glass and boasts high transparency, superior flexibility, and excellent adhesion. It can firmly connect the glass layers like an invisible bridge, buffering against external impacts and preventing glass shattering and splattering. It is widely used in the aviation field, laying a solid foundation for safety and performance.

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.
