Safety Building Window Film

Nowadays, with the advent of consumer upgrading, private cars have entered more and more ordinary families as a means of transportation, and it has become a standard after purchasing a car to apply appropriate car thermal insulation film to it.

Visible light transmittance, UV barrier rate, anti glare rate, thermal insulation rate... These common parameters of automotive thermal insulation films are no longer unfamiliar to consumers, and have become an important reference for purchasing automotive thermal insulation films.

The above performance indicators are important, but they ignore one of the most important performance parameters of automotive thermal insulation film - service life!

The service life is the basis for the optical performance parameters (transmittance, UV barrier, anti glare, thermal insulation, etc.) of the automotive safety explosion-proof thermal insulation film not to undergo significant attenuation during the use of the automotive thermal insulation film.

"The more expensive all automotive safety explosion-proof and thermal insulation films are, the better. Ultimately, it is important to learn to experience and compare the performance of automotive safety explosion-proof and thermal insulation films, and also pay attention to the service life of automotive safety explosion-proof and thermal insulation films.".

Service life of automotive thermal insulation film

How long is it?

Dye film

Features: heat absorption without insulation, short service life

Service life: about 1 year

First of all, let's talk about inferior films. This type of film is mainly a dyeing film. Its production method is to directly apply pigment to the surface of the substrate film, which is similar to our usual painting methods. Because no special technology is used to stabilize the film, it is very easy to fade, and its service life is basically around 1 year. However, because it is difficult to clean after fading, and some light transmittance is not good, So this kind of film is basically invisible now.

Vacuum thermal evaporation film

Features: Poor clarity, severe reflection

Service life: 2-3 years

Vaporization film is the most common film on the market today. It uses a vacuum evaporation technology. Its main production method is to melt and evaporate specific metals onto the substrate film at high temperatures. The biggest advantage of this method is that it is relatively uniform, with guaranteed light transmittance, and because metal atoms adhere to it, it also looks better after being affixed, looking like a mirror from the outside.

However, because it only allows metal atoms to naturally evaporate and adhere to the substrate film, its service life is not long, and generally it will fade after 2-3 years.

Sputtering film 

Features: High definition, stable thermal insulation

Service life: 5-10 years or more

Magnetron sputtering film is the most advanced film on the market, and films sold for thousands of yuan are generally made using this technology.

The production of this film requires using a low-pressure inert gas environment to allow high-speed electrical ions to impact metal or ceramic materials, allowing these materials to be sputtered onto the substrate film to form. Due to a certain sputtering force, the service life of this film will be much longer than that of the vapor deposited film. Generally, if used normally, the service life can be up to 5 years or more.
