The operating environment of rail transit is complex, and the windows are subjected to environmental factors such as ultraviolet rays, temperature changes, humidity, and oxidation all year round. TPU bulletproof film has good ultraviolet resistance and can effectively prevent degradation caused by ultraviolet rays. After long-term exposure to sunlight, its physical properties remain stable, and it is not easy to become brittle or discolored, which can ensure the transparency of the windows and protect the passengers' vision.
Whether it is a cold winter or a hot summer, TPU bulletproof film can handle it calmly. It has a wide operating temperature range and can still maintain good performance under extreme temperature conditions. It can also maintain its functionality in an environment with alternating hot and cold, and will not fluctuate in performance due to temperature changes, greatly extending the service life of the windows.
In terms of humidity, TPU bulletproof film has low hydrophilicity and can effectively resist the penetration and influence of moisture. Even in a high humidity environment, it can maintain good mechanical properties and structural stability to avoid problems such as mold and corrosion caused by humidity. This is especially important for some rail transit vehicles that often operate in humid areas.
In addition, when exposed to oxygen in the air, TPU bulletproof film exhibits high oxidation stability and is not easily affected by oxidation reactions, further ensuring its long-term performance in various environments.
TPU bulletproof film has significant weather resistance advantages, providing reliable protection for rail transit window protection. With the continuous advancement of technology, TPU bulletproof film is expected to play a greater role in the field of rail transit and escort passengers' safe travel.
