As a car protection product, car stickers are loved by many car owners. They are basically installed when they buy a car, but there are also some Xiaobai who don't understand and pay attention to these car aftermarket products. After buying a car, they know that many cars running on the road actually have a layer of film on the glass, but they basically don't know what the film is for, Lack of some basic knowledge about automobile thermal insulation film, especially about inferior film. I don't know how to avoid it. The following small series summarizes several characteristics of inferior automobile thermal insulation film for you.

1、易划伤。因为车窗会被经常升起或者是降下来，质量好的汽车隔热膜表面都有一层防刮层，劣质的膜没有，所以很容易在使用的过程中产生划痕，影响美观。

1. Easy to scratch. Because the windows are often raised or lowered, there is an anti scratch layer on the surface of high-quality automobile thermal insulation film, but there is no low-quality film, so it is easy to produce scratches in the process of use, affecting the appearance

2、不清晰。玻璃车窗是我们车内人观赏外部景物的主要通道，尤其是对驾驶员来说，他会通过玻璃来正确的判断路况，但是劣质的汽车贴膜贴上去以后会有雾蒙蒙的感觉，清晰度不高，有的看物体甚变形。

2. Not clear. The glass window is the main channel for people in our car to watch the external scenery. Especially for the driver, he will correctly judge the road conditions through the glass, but after the inferior car film is pasted, it will feel foggy, the definition is not high, and some look at objects and even deform.

3、会起泡。劣质的隔热膜采用的材料低廉，并且经过阳光的暴晒后释放出甲醛，苯等对身体有害的气体，如果夹在玻璃跟膜之间排不出去，就会形成气泡，难看还影响视线。

3. Blisters. The inferior thermal insulation film adopts low-cost materials, and releases formaldehyde, benzene and other harmful gases to the body after exposure to the sun. If it is sandwiched between the glass and the film, it will form bubbles, ugly and affect the line of sight.

4、有刺鼻的气味。劣质的汽车隔热膜的胶层中会有大量的甲醛、苯等，为的就是能够延长汽车隔热膜的使用寿命，但是这些物质不稳定，会释放出大量刺鼻的气体，揭开膜的保护层以后就可以闻到。夏季高温天气时，异味更强烈，损伤人体健康。

4. It has a pungent smell. There will be a large amount of formaldehyde, benzene, etc. in the adhesive layer of inferior automobile thermal insulation film, in order to prolong the service life of automobile thermal insulation film, but these substances are unstable and will release a large amount of pungent gas, which can be smelled after uncovering the protective layer of the film. In high temperature weather in summer, the peculiar smell is stronger and damages human health.

5、掉色。劣质汽车隔热膜着色层在粘胶层里面，用手指扣刮粘胶层就会有掉色的现象，其实如果你使用一段时间，隔热膜经过紫外线照射一段时间以后，还会有褪色的情况。

5. Fade. The colored layer of inferior automobile thermal insulation film is in the adhesive layer. If you scrape the adhesive layer with your fingers, there will be color fading. In fact, if you use it for a period of time, the thermal insulation film will fade after ultraviolet irradiation for a period of time.
