Are Bubbles in Car Window Tinting Film Harmful to Human Health?
1 Answers
Bubbles in car window tinting film can indeed be harmful to human health, with both indirect and direct hazards. High-quality window film not only significantly reduces UV radiation and lowers the interior temperature during summer but also protects privacy inside the vehicle. Indirect Hazards: When the tinting film bubbles, it releases a large amount of formaldehyde. The sealed environment between the film and the glass is compromised, allowing toxic gases to disperse inside the car. After prolonged exposure to sunlight, the formaldehyde levels in the car may rise due to the presence of formaldehyde in floor mats, films, and interior paint. Excessive formaldehyde in the car can irritate the respiratory tract and skin mucous membranes, posing health risks, and in severe cases, may even lead to leukemia and cancer. Direct Hazards: Large bubbles in the tinting film can obstruct the driver's view, making it difficult to judge objects ahead, potentially leading to accidents. Methods to Identify Quality Window Film: The first method is to "look." Hold the film up to sunlight and observe its transparency. Avoid films with very low transparency as they can impair visibility, affecting driving safety. The second method is to "feel." High-quality films reflect infrared rays, significantly reducing the interior temperature. To test the heat insulation, simply block the sun with the filmed glass and feel the difference with your face or hand. The third method is to "touch." Premium films are highly resilient and can hold shattered glass together, preventing injuries from flying shards. They also have strong impact resistance. In contrast, low-quality films feel soft, lack durability, and are prone to aging and brittleness.
