Generally speaking, the following kinds of car films are favored in the market:
1. Gu Wei: Needless to say, it is recognized as an expensive membrane in the market at present, and its heat insulation effect and ultraviolet resistance are really good. Aside from the price factor, its film texture is soft and scratch resistance is not very good. As we all know, the curvature of the side window of the new Accord is large, which is easy to cause serious scratches on the film.
Advantages: good heat insulation effect, good anti-ultraviolet effect and few fakes.
Disadvantages: Soft texture, poor scratch resistance and high price.
Price: the front gear and the car body should be able to draw a price of 2500-3000 yuan, which is not worth it.
2. Johnson & Johnson: The price/performance ratio is good, but now fakes are rampant in the market, and it is difficult to distinguish authenticity. Johnson & Johnson's new security label was copied. However, Johnson & Johnson has a hard texture and good scratch resistance.
Advantages: good cost performance and good scratch resistance.
Disadvantages: There are too many fakes to distinguish.
Price: the front gear plus the body should be around 2000 yuan.
3. Ray-Ban: Many users, good quality, but few real goods.
Advantages: good transparency and various colors.
Disadvantages: There are many fakes on the market.
Price: the front gear plus the body should be around 2000 yuan.
4.3M: Fake films are also everywhere, with fewer colors, but the real film is a classic, and the effect of filtering ultraviolet rays is also good.
Advantages: Classic color.
Disadvantages: too many fakes, less colors and poor scratch resistance.
Price: front gear plus body is about 2000-3000 yuan.
5. Yuma: This brand belongs to the mid-range. Because it entered the market late, its popularity is not very high, but its effect is good and its scratch resistance is good. At present, manufacturers have controlled the supply of goods and delivered them to authorized stores. Basically, there are few counterfeit products.
Advantages: good cost performance, good scratch resistance, verified by authorized stores and factories, and few fakes.
Disadvantages: short shelf life, only six years.
Price: front gear plus body 1200 yuan.
6. Dragon Film: This brand is rarely mentioned, but the quality is really good, but because it has just entered the market and the price is high, the sales volume is not very good, and there are few agents who make this brand.
Advantages: Good user response quality.
Disadvantages: there are few dealers and it is not easy to find.
Price: 2500-3000 yuan
Consumers need to do some simple identification when choosing car film, and they can easily get six tricks to identify car film from the following six aspects:
1. Feeling:
The inferior film uses ordinary polyester film as the base material, because of its loose internal structure, easy dyeing and low strength, it has no elasticity, lack of toughness, no texture and easy wrinkling, which can't meet the basic requirements of safety and anti-theft of automobile film, while the high-quality film uses optical grade polyester film, which is mostly neutral in color, thick and smooth to the touch, compact in structure and high in strength, so it has high safety and excellent anti-theft performance.
2. Clarity:
The inferior films are mostly dyed films or aluminized films. As mentioned above, the substrate used is an ordinary substrate, which can not reach the optical level at all. The function of heat insulation or shading is realized by heat absorber, dye or high reflection. The chemical dyes or aluminized components in the film greatly affect the clarity and perspective of the film, and the dark film has poor visibility in rainy days or at night, which affects the driving safety. However, the high-quality film is made of optical quality substrate and magnetron sputtering process, and its atomic structure is denser.
3. Smell:
Inferior film usually uses inferior glue, which contains a large number of benzene and formaldehyde molecules, and will volatilize under sunlight, producing a strong pungent smell, while inferior glue is widely used because of its low cost. PSA glue is used for high-quality membrane, which is colorless and tasteless, and the cost is several times higher than that of inferior membrane. It is mainly used in a few industries such as food and medicine. Inferior film usually adopts dyeing process, so it contains a lot of chemical pigments. Under the irradiation of the sun, these pigments will be chemically decomposed, which may release toxic chemicals, seriously polluting the air inside the car and affecting the health of drivers and passengers.
4. Color:
Dyeing process is the main principle of inferior film, which is similar to cloth dyeing. Therefore, when these pigments are adsorbed on the film surface, not only the color uniformity and stability are poor, but also the color difference is serious, and it is easier to fade and become blurred. High-quality thin film is made by magnetron sputtering process, which absorbs precious and rare metal atoms such as gold, silver, nickel and titanium through strong magnetic field. It not only has uniform color, but also has natural space metallic color, high visibility and excellent permeability, which is very suitable for automobile glass.
5. Anti-scratch:
There is no scratch-proof layer on the surface of inferior film, which is easy to scratch when lifting the window or wiping it by hand; If you gently wipe with alcohol or gasoline for 1 min, the inferior film will change color, while the surface of the high-quality film has a professional scratch-resistant layer, such as the patented DUROGARD scratch-resistant layer on the surface of the canopy film, which is not only more scratch-resistant and difficult to scratch, but also will not change color after being wiped with alcohol or gasoline.
6. Technical parameters:
Visible light transmittance, visible light reflectance, thermal insulation and ultraviolet blocking rate are commonly used performance indexes of automobile film at present. According to the optical principle, the basic relationship between the first three indexes is: the higher the light transmittance, the lower the heat insulation rate; The higher the reflectivity, the higher the thermal insulation rate, and the high reflectivity will bring great hidden dangers to the safety of riding. Therefore, the three requirements of high light transmittance, high heat insulation and low reflectivity are the highest realm of automotive film technology today. Car owners must weigh and compare when choosing a car film, and they can't choose a highly reflective car film simply for high heat insulation.
