Automotive Solar Films refer to films pasted on the surface of automobile glass, commonly known as explosion-proof films. In addition to heat insulation and light isolation, they also have explosion-proof functions. High-quality explosion-proof films use special polyester films as substrates. , The film itself has strong toughness, and with special pressure sensitive glue, in the event of an accident, the film will be stuck firmly after the glass breaks without splashing and hurting people. Automobile explosion-proof film also has the function of one-way perspective and glare reduction.
Since the automobile solar film came into the market, it has successively gone through the four stages of "dyeing film", "metal reflective film", "heat absorption film, and intelligent spectrum selective film".
"Dyeing film" is a first-generation product, commonly known as tea paper. It is characterized by strong shading and simple installation; the disadvantage is that it is not heat-insulated, easy to fade, and easy to degummed.
"Metal reflective film" is a second-generation product. It uses a new type of viscose and a thicker film to improve the explosion-proof effect. It has a certain degree of heat insulation and sun protection. The heat insulation rate is between 20% and 60%. It is about 80%.
"Heat absorption film" is a third-generation product. Compared with the first two automotive films, the UV blocking rate of this film is increased to 90%-100%, and the infrared blocking rate is increased to about 30%-95%. The performance is stronger, so as to achieve the effect of reducing the thickness of the film and improving the explosion-proof performance. Adding an endothermic agent to the film to insulate through the principle of endothermic heat. When the heat absorption of the endothermic reaches saturation, it will not absorb heat again. After a long time of endothermic and exothermic heat, its performance will gradually decrease over time, and the glue will The chemical substances in the film will slowly radiate into the room as the film heats up, which is harmful to human health.
"Smart Spectral Selection Film" belongs to the fourth generation of products. It distributes a variety of precious metals evenly on the PET substrate through magnetron sputtering technology, selectively filters in visible light, blocks infrared and ultraviolet rays, has high heat insulation, high light transmission, High sun protection, low reflection, high toughness film increases glass explosion-proof coefficient, driving safer.
