Auto Film Can Be Divided Into Four Categories
Auto Film can be divided into four categories.
The first Auto Film is coated and composite process film, the main role is to block the intense solar light, this kind of Auto Film is earlier production, basically does not have the role of heat insulation, early called the Sun paper, also known as tea paper.
The second kind of automobile film is the dyeing film, the market sees the dyeing automobile film mostly is the deep dyeing craft, to the deep dyeing technique raises the endothermic agent, absorbs the sunlight the infrared rays achieves the heat insulation effect. Because it also absorbs visible light, resulting in visible light penetration rate is not enough, coupled with its own process limited, poor clarity. Another major weakness of this type of film is that the insulation function decays quickly and is easily faded and relatively inexpensive.
The third kind of automobile film is the vacuum heat evaporation film, uses the vacuum heat evaporation process, is the aluminum layer evaporates on the base material, achieves the heat insulation effect. This is also commonly referred to as the metal film field, with a longer lasting thermal insulation, but the weakness is not high clarity, affect the visual field of comfort, another major weakness is reflective higher.
The fourth kind of automobile film is metal magnetron sputtering film. This is the highest technology of the glass film, produced in the late 1990s, experienced a variety of technological innovations. Using the principle of electric field and magnetic field, the metal particles are uniformly sputtered on the high tensile pet substrate by high speed. In addition to the products with good metal texture and stable thermal insulation properties, the magnetron sputtering process has the same clarity and low reflective and lasting luster as other processes.
