Car Window Sun Control Tint Films

Window film, also known as solar film, is a one-way perspective film applied to the windshield and window glass for heat insulation, explosion prevention, and dizziness prevention. What is a high-quality solar film and how should it be selected?

In terms of hand feel, the difference in the quality of solar films is their tactility and usability. High quality solar films have many production processes, and their surfaces undergo multi-layer treatment, resulting in a smoother and more textured feel. The surface will not leave scratches after long-term use, and has good wear resistance; Poor quality car films are simply packaged and feel rough, thin, and brittle to the touch, leaving scratches after use and poor wear resistance.

From the perspective of perspective, high-quality solar films, regardless of color depth, have a high degree of perspective. Ordinary solar films are dyed and processed to achieve thermal insulation through color, so the color is relatively dark, and there is always a misty feeling when viewed from inside the car.

In terms of color, most of the inferior films on the current market are directly colored by adding pigment to the surface of the film using adhesive, and solar films produced using this adhesive coloring method often fade after exposure to sunlight. If the discoloration is severe, the original colored film can even become transparent. The high-quality solar film adopts a metal sputtering process, and is coated with high-grade metals such as nickel, silver, and titanium on a high tension natural film for coloring. It does not fade during daily use. When purchasing, the vehicle owner can spray a small amount of carburetor cleaning agent on the film to be tested, or pour a small amount of gasoline to graffiti on the film. At this point, the color of the high-quality film will not be scraped off, while the discoloration of the inferior film is quite serious.

In terms of smell, because the solar film is attached to the vehicle, the smell emitted by the solar film often affects the physical health of the people inside the vehicle. High quality thin film manufacturing processes are complex, highly technical, and can only enter the market through health and safety testing. Even if exposed to sunlight, it will not produce volatile substances harmful to human health. The manufacturing process of inferior film is simple, and the material cost is low. After tearing off the transparent adhesive layer, the smell is pungent, dizziness, and nausea can occur. Long-term use can cause serious harm to the human body.

In terms of thermal insulation, we need to test the thermal insulation protection of the solar film. The thermal insulation rate of high-quality solar films should reach over 80%, which is 3-4 times that of ordinary color films. High quality solar films can block ultraviolet rays by over 99%, providing effective protection. On the contrary, most common color films are only dyed from transparent films through adhesive, which has a poor ability to block ultraviolet rays. Sunlight can easily cause aging and discoloration of items inside the vehicle, and can also cause damage to the skin of passengers inside the vehicle. There is also a simple way to identify the UV resistance of solar films: first place a piece of RMB under the film, and then use the ultraviolet light of a banknote detector to test the banknote through the film. If the watermark on the banknote cannot be displayed, it indicates that the film can effectively block ultraviolet rays, otherwise, it indicates that the film has a poor ability to block ultraviolet rays.
