Where Should Car Film Be Applied?
1 Answers
Car film refers to a thin layer applied to the front and rear windshields, side windows, and sunroof of a vehicle. Its primary functions include blocking ultraviolet rays, reducing heat, preventing injuries from shattered glass, and minimizing glare. Additionally, due to the one-way transparency feature of solar films, they serve to protect personal privacy. Car film is applied to the exterior glass surfaces of the vehicle. Wear-resistant layer: Composed of wear-resistant polyurethane, it resists friction damage from regular cleaning. PET safety base layer: Made from high-strength, high-transparency PET polyester and pigments through melt extrusion and biaxial stretching, it can also incorporate dyes to produce films of various colors. Metal insulation layer: Metal plating is a common insulation technique, where aluminum, silver, nickel, and other nanoscale metal layers with high infrared reflectivity are sputtered onto PET film using vacuum deposition or vacuum magnetron sputtering. Composite adhesive: Consists of weather-resistant, high-transparency polyurethane adhesive. UV absorption layer: Contains special UV absorbers to block 99% of ultraviolet rays. Transparent PET safety base layer: Made from high-strength, high-transparency PET polyester film, it sandwiches the metal layer to prevent oxidation and extend the film's lifespan.
