The difference between metal film, magnetron film, and ceramic film

Ten cars, nine stickers. The first thing a new car owner does after receiving the car is to consider applying car film.

metal film

Currently, most of the films on the market are metal films,

Principle: Metal film utilizes the metal on the surface of the film to reflect a portion of sunlight (ultraviolet, infrared, visible light)

Single layer metal film: Sputtering aluminum, iron, titanium and other metals on the film to achieve thermal insulation effect

Advantages: cheap; Good privacy; Good insulation performance

Disadvantages: Poor transparency; Has an impact on the signals inside the car; Will cause secondary radiation; Will oxidize

Comment: Currently, this type of film is the most common on the market, with high cost-effectiveness, but it has an impact on GPS signals

Multilayer metal film (magnetron film): Using magnetron sputtering technology, materials such as nickel, silver, titanium, gold, ceramics, etc. are sputtered in multiple layers onto the film.

Advantages: High clarity, high insulation

Disadvantages: expensive; The same impact on GPS signals; Easy to oxidize

Comment: High end films commonly found in the market have good transparency and also have an impact on GPS signals.

Ceramic film: Ceramic film developed relatively late in the Chinese market. By sputtering ceramic materials onto the film, it achieves the effect of blocking heat (metal film is reflective)

Advantages: Good thermal insulation performance; High transparency; Stable quality; Do not block GPS signals

Disadvantages: expensive; Less selectivity; Many fake ones

Comment: In terms of overall performance, ceramic film is a good choice. Pay attention to distinguishing between explosion-proof films on the market that use organic IR and impersonate ceramic films. Organic IR is very easy to decompose, and its insulation function will quickly deteriorate.
