Window films, car wraps, and color-changing films are the more common types of car films nowadays, which respectively bring heat insulation, protection, and color change to the car. The functions are different, and the product structure is also slightly different. Today, let's take a look at the structural comparison of the three membranes.
1. Window film
Window film, also called heat insulation film and solar film, is mainly installed on car side windows, sunroofs, rear windows, etc. Now the industry is also paying attention to the application of front guard film.
Window film is mainly divided into two types according to different insulation materials, namely metal film and ceramic film.
Among them, the metal film with better performance is mainly plated on the PET substrate through the magnetron sputtering process. Depending on the metal coating, there are single-layer silver and multi-layer silver.
Ceramic insulation films generally apply nanoceramics to the substrate through a coating process.
2. Car clothing
Car cover mainly refers to invisible car cover, also called paint protection film. It is named invisible because of its transparent properties. With the development of application needs, car clothing gradually overlaps with color-changing film, and categories such as colorful car clothing and real paint film appear. The main feature is that TPU film is used as the base material.
Structurally, the car clothing film is composed of upper and lower layers of release film, functional coating, glue, and TPU base film.
3. Color changing film
Color-changing films are mainly used to meet the need to change the color of cars. In the early days, they were mostly popular in modified cars and second-hand car renovations. Now, thanks to the market development of new energy vehicles and the growth of personalized needs of young car owners, the market potential of color-changing films has been The industry is optimistic about it.
The structure of the color-changing film is closely related to the process. There are two main types: calendering and casting. Calendering is more common. The structure is similar to that of car clothing. The main difference lies in the different base materials.
The above is a brief analysis of the structure of the three films of window film, car clothing and color-changing film. Currently, many automotive film companies have the R&D, production and sales capabilities of the three films. In the future, it is expected that the three films will go hand in hand and jointly bring a variety of aspects to the automotive aftermarket. product experience.
