About the car film had to say

Not yet to the scorching summer, the beauty-loving girls are ready for the summer sunscreen. Car friends, of course, will not be jealous of the car. Give the car a layer of protective film to give it a double sense of security. A good quality car film can filter part of the glare and effectively prevent some of the light from entering the car. However, at present, there are many mixed lights in the automotive film market, and fakes are rampant. Many may not be particularly good friends, and they will inevitably face difficulties in selection, even who fall into the trap. in. Here's what we have to say about car stickers.

First of all, we must make it clear that the over-thickness of the heat-insulating film may pose a potential safety hazard because it will block the driver's line of sight. The automotive insulation film is divided into front and rear windshield films and side windshield films. The most demanding insulation film is the front windshield. Due to driving requirements, the front windshield has the highest requirements for light transmittance. Ultraviolet penetration, can make the skin melanin deposition, resulting in black skin, excessive UV exposure is likely to cause skin aging and disease, but also easy to make the car equipment fade aging, but also should be blocked as much as possible. In other words, the focus of automotive film is to isolate ultraviolet and infrared rays from the sun. At present, there is no direct relationship between the heat insulation effect and the color depth of high-quality automotive insulation film (especially the front-shield film, with clear top).

Secondly, most of the current films are multi-layer composite films, and metal films refer to films that contain metal thermal insulation. This layer of metal heat insulation layer is treated with a special process on a PET film (PET polyester-based film) and coated with a metallic nano-metal layer of aluminum, silver, and nickel. Aluminum, silver, and nickel were selected because of their high electrical conductivity, shallow depth of penetration, and high reflectivity to infrared rays. Metal foils do cause the GPS signal in the car to be blocked, which is determined by the nature of the film itself. If you need to ensure the smooth flow of signals, you can choose non-metallic film.

Finally, we must tell everyone some "traps." The manufacturing cost of automotive film is very low, basically there is no threshold limit. Many small workshops also started to produce so-called car films. Some of them used to make huge profits. They even sprayed plastic cloths with different colors of plastic to become car films. When a car film is purchased, car owners must not go to the street because they are greedy for a small amount of money. Stores, must choose a regular brand shop, choose the sun film transmittance of more than 85% of the best, depends on whether there is a brand authorization certificate, authorization period expires. Different brands of car foil prices are also different, but the same brand sold in different shops, sometimes there are large differences in prices. Therefore, car foil to shop around or first check the information on the Internet, and then comprehensive assessment, and according to their actual purchasing power, which products to buy again, to prevent falling into the business car sticker price trap. To distinguish between the heat-absorbing film and the heat-insulating film, we must stand on the same side of the illumination light and feel the temperature of the light reflected from the film surface by hand. If the heat-absorbing film has only a small amount of heat energy, it will be reflected. Prolonged test exposure will reveal shortcomings in thermal insulation.

Although the summer is clear, but it also makes us hot, we need to pay attention to more security issues, we must always polish their eyes, no matter what you choose, or that sentence is not necessarily the most expensive, but it must be the most appropriate of.
