Why do bubbles form on car film?

　　When buying a car, many car owners will excitedly apply a film to their beloved car. Some are given by the 4S store, and some are bought from car decoration stores. Regardless of the method, after two or three years, some films may have bubbles. It's embarrassing, although it doesn't affect driving safety, it always feels awkward. Today, let's talk about how to eliminate these bubbles to remove your annoyance.

　　It can block ultraviolet rays. Ordinary car windows only block about 19% of ultraviolet rays. Over time, ultraviolet rays (UV) from sunlight will cause permanent damage to the skin through the front and side windows, and the leather, fabric, and accessories in the car will fade in a short time. Quantum film contains UV blockers, with a UV blocking rate of 99.9%, and a lifespan of up to ten years, improving your health index and keeping your car's interior bright and new.

　　Another point is privacy and security. Quantum film has a one-way perspective function. The outside cannot see the inside of the car, but the inside can clearly see the outside. This is very effective in enhancing the privacy of the vehicle, making the car an extension of your personal private life. At the same time, the quantum film has a thickness of 3 mils and a puncture resistance of up to 13 kg, which is twice that of ordinary front windshield films, providing super safety and explosion protection.

　　The car film is a dyed film. This type of car film mostly uses deep dyeing technology and adds heat absorbers to absorb infrared rays in sunlight to achieve heat insulation. The heat insulation effect is very poor, and the visible light transmittance is poor. In rainy or nighttime conditions, it is basically impossible to see clearly when reversing. Another disadvantage of this film is that the heat insulation function decays quickly. After one or two summers, the color of the film basically fades and becomes transparent and easily bubbles!

　　Therefore, car film is applied to the inside of the glass, which can first avoid damage caused by the external environment. Secondly, if an accident occurs while driving and the car glass is broken, a good quality car film will generally stick to the glass fragments to prevent the driver and passengers from being injured by the glass fragments a second time, and also improve the safety of the driver and passengers.

　　The lifespan of sun films varies depending on their quality. There are two manifestations when the lifespan expires: 1. Severe fading, 2. Bubbling and bulging. If the sun film bubbles, please tear it off immediately and replace it with a new film! Bubbling sun films release a large amount of formaldehyde, especially after being exposed to strong sunlight! Long-term use of bubbling sun films will seriously damage the health of passengers in the car, and may even cause cancer.

　　Some car films are not installed properly. That is to say, the technician who installs the car film is not skilled enough or careless and did not install the film well. So have you noticed that the parts that are prone to bubbling are mainly concentrated on the rear windshield? Why is this? Reason one, there are many heating wires at the rear windshield, which will affect the construction to a certain extent, so it is easier to have small bubbles. Reason two, due to the existence of heating wires, heating the rear windshield will cause the car film to heat up, which will also cause bubbles in the car film.

　　Therefore, it is recommended that car owners avoid washing their cars within three days after applying the car film to prevent the film from falling off due to undried water. The rear window defogger should also be avoided for a week, as undried water can also have an adverse effect on the defogger. After installation, you can use a damp towel, sponge, or soft cloth to wipe the film surface. In addition, after a period of time after applying the film, you will find that there is hazy water vapor inside. This is a normal phenomenon during the drying process of the sun film, and it will gradually disappear after a while.

　　However, if there are many large bubbles, this method is unnecessary. It is recommended that you tear it off and reapply it. This is because if a large number of bubbles appear, it is obviously a quality problem with the car film. If it is not replaced, in the summer high temperature, there will be a bad smell emanating into the car, and it will also affect the reversing vision. High-quality car films often have good wear resistance, and the film layers use special high-performance resin adhesives, with excellent adhesion, so that the edges of the film and the edges of the glass are only 2 mm apart and are not easily worn off, and the scratch-resistant coating makes it have strong scratch-resistant performance and a long lifespan, making it easy to maintain. Raising and lowering the windows can easily scratch the film surface. Inferior films will be scratched after one or two months. Choosing high-quality car films can avoid this situation.

　　So what should you do if the car film bubbles after being exposed to the sun? Experienced repairmen suggest that if the bubbling area is large, it is recommended to reapply a new one. If there are not too many bubbles and the bubbles are not large, you can open a small hole and then use a scraper and a hair dryer to slowly scrape it flat.

　　If there are only a few small bubbles, it's even simpler. Just pierce them with a needle and press them flat. When choosing car films, the price generally ranges from 1000 to 3000 yuan due to different brands and quality. Inferior car films will have bubbles and curled edges after being applied for a period of time, so it is still recommended that you apply better ones; and it is best to have professionals apply the film.
