Tinted Window Film For Car

It is almost a month into summer, and the temperature will gradually increase. Be prepared for the high temperature. A suitable window insulation film should be just needed. High quality insulation film can effectively block ultraviolet and infrared rays, reduce the temperature inside the car, and effectively protect the car and the driver.

The following experience, based on years of practice by older drivers and combined with scientific data, will teach you how to choose a suitable and good film for yourself and "avoid the pit.".

How to judge whether a membrane is good or not?

Three hardness indicators of thermal insulation film:

1. UV insulation rate

2. Total solar barrier ratio

3. Light transmittance

First of all, a thermal insulation film that meets the national standard must have a UV insulation rate of 99%. If it cannot even reach 99%, it is an unqualified product. Don't look at it. The higher the total solar insulation rate, the better the thermal insulation effect. However, when looking at the total solar insulation rate, it is also necessary to look at the transmittance parameter, because the film cannot be completely black, especially the front and side shields. Therefore, the requirements for thermal insulation films are high overall barrier efficiency and high light transmittance.

Which kind of metal film is better than ceramic film?

The two main series of window films are based on two heat insulation methods

Metal films achieve thermal insulation by reflecting heat.

For metallic materials, the metal components with the best thermal reflection effect are gold, silver, aluminum, nickel, and copper. Everyone is familiar with it

The "magnetron sputtering metal film" was developed through the upgrading of the "vapor deposition technology" under the general idea of reflecting thermal energy.

Ceramic membranes achieve thermal insulation through the absorption of heat by ceramic particles.

Current mainstream ceramic film: Its working principle is to attach heat absorbing materials such as titanium nitride (TiN material coated by magnetron sputtering), ITO (indium tin oxide plated by magnetron sputtering), ATO (tin antimony oxide antimony doped tin dioxide), etc. to PET to achieve the purpose of absorbing infrared rays.

Therefore, if the two films are exposed to the sun for a long time, the ceramic film will feel warmer to avoid the metal film. After sticking to the car, the ceramic film ceramic magnetic particles will slowly radiate their Siman energy into the car, such as Tesla Green Bean 3,

So if conditions permit, stick the metal film in one step. After all, ceramic film is not much cheaper

The car glass has a color (green or blue-violet), but does it have its own thermal insulation function?

This is not necessarily the case. It depends on the vehicle type. For example, the original glass of high-end vehicles (Range Rover, and Mercedes S-Class) contains a metal thermal insulation layer, and the glass will correspondingly appear green or bluish purple. The measured thermal insulation performance of these original glass products is indeed excellent. If it is not a high-end car, and the glass appears green, it is mostly due to the addition of chromium oxide dye by the manufacturer, the thermal insulation performance is no different from that of white glass.
