There are many brands and you can go to a car accessories store to choose a car film suitable for different vehicles.

Selection of car film:

1. Dyeing film. It refers to the lowest-grade car film. This film is thin, has no heat insulation, and is easy to fade. They are usually found in small shops and are very cheap. It only costs one or two hundred yuan to cover the entire car. "Fading of tooth waist" is its most striking feature. This kind of membrane is generally produced in Taiwan, my country.

2. Coating printing film. It is a unique craft in Korea. Generally thicker. This kind of film has better thermal insulation, but has slightly poor transparency.

3. Ordinary metal film. It is made by sputtering metal on the colorless original film layer. Generally, the metals used are aluminum, iron, etc. This kind of membrane is generally produced in India, Japan, the United States, etc. The most common one on the market is this metal film. However, this kind of film has average transparency and average heat insulation, but its price is not low. General beauty shops often use this kind of film to pass off as top-grade film. Many well-known brands are actually just ordinary metal films. Because they entered the market earlier, consumers mistakenly think that this film is a high-end film.

4. Nano ceramic membrane. High-end film is made by using nanotechnology to spray "silicon" particles onto the colorless original film layer. This film has good heat insulation and is clear. It is a new technology product and has the characteristics of not interfering with electronic signals and being environmentally friendly. . Generally produced in Japan.

5. Precious metal film. As the name suggests, this kind of film also splashes metal on the colorless original film layer, but the difference is that the splashes are precious metals such as chromium, titanium, and platinum. In addition, the sputtering method of this film is "magnetron sputtering". It's a complex process, and only the United States has the technology. The characteristic of this film is its pure color. The "UBO" sold by Li Car House and the "Weigu" on the market are this kind of film.

6. Double-layer precious metal film. Only the CPFILM factory in the United States has this highest-grade explosion-proof insulation film. This kind of film uses the latest magnetron sputtering (SPUTTER) process to spray precious metals such as titanium and platinum onto both sides of the colorless original film layer. Make this membrane have a double layer of metal. Therefore, it is low-reflective, maintains a constant temperature in the car, and reduces fuel consumption. Moreover, the color is crystal clear and has the characteristics of one-way light transmission. When viewed from the inside, it is crystal clear and transparent, and when viewed from the outside, it appears looming. The brand "Weibang" owned by Dingli Glass Functional Film Company is this kind of film. It can also effectively block 99% of ultraviolet rays and protect your skin.

7. Identify the quality of the film. The film with a delicate and not rough feel can feel its thermal insulation effect, the higher the thermal insulation rate. If you tear off the mask and rub it on the ground, the color will fade. It is an ordinary film, but it is an explosion-proof film.

8. Touch and feel: Inferior car wraps often feel thin and soft, lack sufficient toughness, and are prone to wrinkles, while high-quality car wraps feel thick and smooth. , with texture.

9. Smell with your nose; take out a small piece of car film, tear off the inner protective film, and use your nose to ask. Inferior car film will have a smell. It is not good to use glue for such car film. Don't buy it.

10. The car film that looks good to the eye has high perspective and strong clarity. Although the color of the film is dark, you will not feel blurred when you take a piece of film indoors and look out.

11. Use alcohol or gasoline; because the inferior film is dyed with glue, remove the inner protective layer of the film and then wipe the glue layer, and you will see fading. You can also peel off the transparent layer on the back of the car film and scratch it with a hard object. Inferior films will fade more seriously.

12. Check the authorization certificate of the car film shop and the technical parameters of the car film provided by the car film manufacturer. Usually, the more transparent the film, the lower the heat insulation; the more reflective the film, the lower the heat insulation. The higher. Films with high light transmittance, low reflectivity and good heat insulation are high-quality films with higher prices. Just like the "Tianji Car Film" film itself, it has high light transmittance, low radiance and good heat insulation. This is the result of certification obtained by more than 100,000 car enthusiasts.

13. Test the insulation effect. The heat insulation rate of high-quality explosion-proof film should reach about 60%. The heat insulation rate of inferior film is low and you will feel stuffy when sitting in the car. At the same time, it has poor ultraviolet shielding effect and cannot protect the items in the car and the passengers. role. Test method: Use a high-power incandescent lamp to simulate the source of sunlight and test the film's ability to block heat.

14. Anti-scratch; Anti-scratch is a basic performance of automobile film. When high-quality film raises and lowers the car window normally, the surface of the film will not be scratched, while inferior car film

There are obvious flaws in this aspect.

Test method: Put two pieces of film into the water, rub the fronts of the two pieces of film face to face with your hands for a few times, and see if there are any scratches on the surface of the car film.

Fifteen. The craftsmanship of the film technician; a professional film technician should have received technical training from the automotive solar film manufacturer and hold the relevant certificates of a professional automotive film technician. Before the film master applies the front and rear windshields The whole sheet should be used for paving, and the collage must not be separated. The solar film should be affixed to the car glass as much as possible.
