The car film is to put a layer of film on the front and rear windshield, side window glass and skylight of the vehicle, and this layer of film is also called solar film or explosion-proof heat insulation film. So, what are the types of car stickers? If the film is divided into categories according to the process, the general classification is only 4 generations: the first generation dyeing film (tea paper), the second generation metal film, the third generation multi-metal magnetron sputtering film, and the fourth generation nano ceramic membrane.
1. Dyeing film: Also known as tea paper, this type of automotive film is an earlier product and does not have the ability to block infrared and ultraviolet rays. The film surface is easy to age, easy to fall off, easy to fade, no explosion-proof performance, only has hidden performance. .
2. Metal film: On the colorless original film layer, common metals such as iron, aluminum, or stainless steel are vacuum-plated. This kind of automobile film has general transparency and general heat insulation, but the price is not low. Most beauty shops often use this film as a top film. Many well-known brands are actually just this kind of ordinary metal film. Since they entered the market earlier, consumers also mistakenly think that this film is a high-end film.
3. Multi-metal magnetron sputtered film: Use optical grade PET material to evenly sputter multiple layers of precious metals (silver, indium) onto the substrate under vacuum. The color is fine, the light transmittance, the clarity is higher, the heat insulation is higher than the single-layer metal film, the ultraviolet radiation and the explosion-proof are strong, the heat insulation rate is as high as 85%, it is the most advanced film production technology with good heat insulation performance.
4. Nano-ceramic membrane: high-grade membrane is made by spraying "silicon" particles onto the colorless original membrane layer using nanotechnology. This kind of membrane has good heat insulation and clearness. It is a new technology product and has no interference. Features such as electronic signals and environmental protection. It can solve the signal shielding problem of a small part of Japanese car metal film.
