Building sun film and car sun film What is the difference
2, car film and building film can be separated from ultraviolet light, but the absorption of UV layer structure is not the same, car film separated by ultraviolet layer, is a high-pressure plating single layer, building film separated by ultraviolet layer is a vacuum sandwich, containing trace plutonium, Harmful spectrum, tuned spectrum video, car film only in the UV UA play a role in the building film UA and VB are working.
Building film and car film are glass film, the basic substrate are PET, the structure and application process is basically the same, there are safe, explosion-proof, heat insulation effect, if the market that we can interoperate, this is a Consumption misunderstanding.
The difference is that:
1, the metal content requirements are not the same, the volume of cadmium nickel and titanium can not exceed 5%, the building film can not exceed 2.5%, in this request only in line with the overall requirements of environmental protection, because the general car for adults and healthy people, And people can not live long life in the car, and the building room, including pregnant women, babies and sick and sick people, rare metal radiation on the fetus, the baby's growth there is a certain impact, so the building film rare metal content can not exceed , Should follow the strict environmental protection standards.
3, building film and car film thickness is not the same, the building film insulation explosion-proof domestic usually 2mil-16mil between the general thickness of 2mil, 4mil, 4.5mil, 8mil
