Where is the ceramic membrane better than the metal membrane?

At present, the automotive film market is dominated by magnetron sputtering metal films. Metal thin film has good thermal insulation performance, especially the multilayer film structure produced by magnetron sputtering technology has reached the peak level in the field of thermal insulation.
Metal thin films have always had congenital defects, such as easy oxidation, shielding ETC, GPS signals, and high reflectivity. Although the price of ordinary single-layer metal film is cheap, but the heat insulation performance is general, and the effect of reflecting heat is not as good as everyone thinks. More by blocking the heat to achieve the effect of heat insulation.
The performance of the multi-layer film structure of the metal film is good, because silver, a highly oxidized metal, is sputtered to reflect heat energy. Although the thermal insulation performance has been improved, oxidation has become the biggest defect; in addition, because the metal layer is thicker than the ordinary metal film, the problem of shielding signal is particularly serious, and even affects the mobile phone signal; in addition, the construction is very difficult, and the metal wire is produced at every turn. Due to the complexity of the production process, the price of the product is very high.
The ceramic membrane concept: pioneered by a Singapore company's brand. Objectively speaking, the overall performance of the product is very good, but because Singaporeans operate the Chinese market and do not understand the Chinese market, the brand has been tepid and missed the Chinese market. The golden age of rapid development.
Ceramic is a general term for nitrogen oxides. Traditional ceramics consist of silica and other materials. The ceramic materials used in the explosion-proof membrane include indium tin oxide and titanium nitride, which have the characteristics of selective filtering of the solar spectrum. Function, heat insulation performance far more than metal, less reflective, excellent stability, after the removal of metal characteristics, will not shield the signal. Amber borrowed the concept of ceramics and introduced ceramic membranes.
