Which is better, metal film or ceramic film?

Ceramic membrane is good, and the front bumper is the most important glass part of the car. The choice of thermal insulation film can not be ignored. Ceramic membrane has better filtration performance for visible light, and metal membrane is bound to be green because it is metal, which has a slight impact on the reception of ETC and the navigation of the original vehicle, and needs additional treatment, while ceramic membrane has no impact.

Difference between metal film and ceramic film of automobile front fender;

The best choice of front barrier film is magnetron sputtering multilayer metal film and nano-ceramic film, which have good selective transmittance for visible light, but there are also differences.

Thermal insulation: Metal film thermal insulation material is a variety of precious metals with selective light transmission, while ceramic film thermal insulation material is a ceramic material (metal oxide without metal) with strong absorption of infrared and ultraviolet rays. As far as thermal insulation is concerned, the performance of ceramic membrane is 80% of that of metal membrane.

Transmittance: The ceramic membrane has a better filtering effect on visible light, and the color is lighter when viewed from the outside. Because the metal film is metal, it will inevitably be green, and the color will be darker from the outside, but there is no difference from the inside.

Influence signal: Both of them have no influence on the cell phone signal, but the front metal film has a slight influence on the reception of ETC and the navigation of some Japanese cars, which requires additional treatment, while the ceramic film has no influence.
