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.
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.
Excellent Transparency, Durability, and Stability
Our products boast optical-grade transparency, superior durability, and stability. They provide military equipment, such as tank glass, with an exceptionally clear field of view, enabling clear observation and accurate judgment in complex battlefield environments. Under varying temperature and humidity conditions, our TPU film maintains precise dimensions and specifications, without thermal expansion or contraction, or moisture absorption deformation that could affect the fit and assembly accuracy of equipment like bulletproof face masks, inserts, and shields. This ensures that in any situation, our products offer a tight, comfortable, and safe protection experience for the user.
Stable Protective Capability
With superior anti-aging properties, it effectively resists UV radiation, oxidation, and erosion from chemical substances. Even after prolonged use, it maintains the material's strength, flexibility, and transparency without showing signs of breaking, discoloration, or degradation. This significantly extends the service life of military equipment, reducing maintenance costs and replacement frequency.
Exceptional Compatibility and Flexibility
Our bulletproof TPU film also boasts outstanding processing adaptability and flexibility, making it easy to be compounded with various different material frames for face masks, base materials for inserts, and shield shells. It can be securely bonded using processes such as thermal pressing and extrusion, forming a tightly seamless protective whole. Moreover, our TPU inter layer film can easily adapt to various complex shapes of protective equipment, tightly conforming to both flat and curved surfaces without any distortion.
