How to distinguish the quality of car window films?
1 Answers
First, pay attention to the 'three rates', namely light transmittance, UV resistance rate, and heat insulation rate, to differentiate the quality of the film. Looking from inside the car, the light transmittance should be very clear, regardless of the film's color depth, ensuring good visibility during night and rainy conditions. For a simple assessment of heat insulation, car owners can use a sunlamp at an auto beauty shop to feel the temperature change after applying the film. Taking the former barrier film as an example, a slightly better car film should have a light transmittance of over 70%, a UV resistance rate between 98% and 99%, and a heat insulation rate above 48%. For side windows and rear bumpers, the film's light transmittance only needs to be above 60%. Secondly, the quality of the film can also be judged by touch. High-quality films feel thick and smooth, with sufficient toughness. On the other hand, inferior films are prone to wrinkling and are thin and soft. Huang Guiyong introduced a tip: if the quality of the film cannot be determined by touch, car owners can take a small piece of the film and scratch it on glass. If the film easily leaves marks or breaks, it indicates low quality and should not be used. Additionally, car owners can peel off the film and smell it. Inferior films often leave a large amount of benzene in the adhesive layer, emitting a pungent odor. Choosing such low-quality products can severely affect the health of car owners.
