Car Film Quality Judgment

One look at the color. Usually, anti-riot films are made of lighter green, sky blue, gray, brown, natural colors and other colors that are more comfortable for the eyes. The color of the explosion-proof membrane is uniform and soft, without any uneven color difference, and the scenery will naturally not change color when viewed from inside the car. Ordinary color film melts the color directly into the adhesive film. After tearing off the upper plastic paper and scraping the adhesive surface hard, the color will fall off. In addition, ordinary color film will fade if you hold it on the ground and wipe it gently.
Second smell. The residual solvent in the adhesive layer of inferior membranes has a high benzene content and will have an odor. However, good membranes have been professionally treated before leaving the factory and have less odor. Experts warn that smelling this odor for a long time will seriously affect the health of car owners.
Three question indicators. The so-called explosion-proof film must have the functions of heat insulation, explosion-proof, and ultraviolet protection. Therefore, when consumers choose, they can consult the sales staff in detail to determine whether the quality is true or false.
Four touch feel. Generally, the thickness of safety explosion-proof film is not less than 1.5mil, so it feels thick and smooth to the touch. In addition, because its surface has been hardened, it generally will not scratch the surface. However, ordinary color film is thin and brittle due to insufficient thickness. When the glass is shaken, marks will be left on the film.
