The difference between automotive film and architectural film
1 Different gums: Automotive film is made of ordinary adhesive (HPR), while most of the building film is clearing rubber (DSA), while the safety film is made of special adhesive. Because of different properties, automotive film The service life is about 5-10 years, and the building membrane is normally used for 25 years.
2 color system is different: the color of the automobile film is black, natural color, green, etc., and the architectural film is rich in color, suitable for various buildings and cut decoration.
3 Safety: The safety and explosion-proof performance of the membrane is related to its thickness. Automotive film thickness is 1.5 mils, while safety film thickness is typically 2 mil-15 mils.
4 Performance: Building membranes and automotive membranes have different requirements for various indicators depending on the application. For example, the front glass of the car, the national standard for the film after the film can not be less than 70%. Some buildings use membranes with higher reflectivity, but they are not usually used on cars. 
5 If ordinary car film is applied to the building glass, the long-term exposure of the building will quickly lead to deterioration of the film backing, film peeling, fading, cracking, etc., which seriously affect the aesthetics of the building.
