Analysis of spectral properties of car solar films

A dual-beam ultraviolet/visible spectrometer (UV-Vis 8500) automatically controlled by computer was used to measure qualitatively and to analyze the spectral properties of car solar films of a certain brand in the market. The experimental results indicate that transparency characteristics of the ordinary series of solar films are well, but their violet insulation and heat insulation properties are moderate, and moreover, their thermal-proof property is not ideal. The heat insulation, violet-proof and transparency properties of the anti-crack series are all in normal level. The heat insulation and transparency properties of anti-crack and anti-wear series are moderate, however, their violet insulation characteristics are better than those of other series mentioned above. For the super front film, its transparency property is excellent, moreover, its violet insulation and heat insulation properties are quite well. In general, it can be concluded that the super front series are the best car solar films.
