How to Choose the Right Car Window Film?
1 Answers
The selection of car window film mainly depends on the following five aspects: 1. Light Transmittance: According to the 'Safety Technical Conditions for Motor Vehicle Operation (GB7258-2012)' of the People's Republic of China, the visible light transmittance of the front windshield and the areas of glass outside the windshield used for the driver's viewing area should be greater than or equal to 70%. Mirror-like reflective sunshade films are not allowed on any window glass. 2. Heat Insulation Rate: Unlike light transmittance, there are no national mandatory standards for the heat insulation rate of car films. Currently, high-quality car films have a heat insulation rate between 45%-65%. The better the heat insulation rate, the less likely the temperature inside the car will rise. 3. UV Protection Rate: Prolonged exposure to large amounts of UV rays can burn the skin and accelerate the aging of car interiors and dashboards, making the UV protection rate a very important indicator. 4. Heat Insulation Materials and Technology: Based on materials and technology, car films are divided into six categories: dyed films, coated printed films, ordinary metal films, nano-ceramic films, precious metal films, and magnetron sputtered films. The material and technology of the film directly determine its clarity, heat insulation, and UV protection capabilities. 5. Warranty Period: Over time, car films may develop bubbles, fade, or lose their heat insulation capabilities. A simple way to measure the quality of a car film is to look at its warranty period.
