Differences between Architecture and Automotive Tinted Film

Many people think that architectural film and automotive film are similar, and use automotive film and architectural film interchangeably. In fact, this is a misunderstanding. If you use ordinary automotive film to stick to the glass of a building, the film will quickly develop due to long-term exposure to the sun. The adhesive backing deteriorates, the film layer peels off, fades, cracks, etc., seriously affecting the appearance of the building. Although both automotive film and architectural film are glass films, their basic substrates are PET, their structures and application processes are basically the same, and they both have safety, explosion-proof, and heat-insulating effects, there are many differences between them.

1. The functions of architectural film and automotive film are different:

Architectural films are mainly heat-insulating and anti-ultraviolet, and also have explosion-proof properties; automobile films are mainly safety-proof and anti-ultraviolet, and also have heat-insulating and anti-ultraviolet properties. Due to their different uses, there are certain differences in manufacturing processes and materials. According to purpose to use.

2. Architectural films and automotive films have different uses:

Architectural film refers to a kind of film specially used on architectural glass, while automobile film refers to a special film specially used on automobile glass. At the beginning of the production of glass film, it was specially developed to solve the energy crisis as a sunshade and heat-insulating energy-saving product affixed to the glass doors and windows of buildings. At that time, people discovered that it could be used in buildings, and later it was also used in buildings. On the car.

3. The production processes of architectural films and automotive films are different:

Generally, because the building is fixed, the visible light reflection of the film produced by the vacuum aluminum plating process is often very high, and the reflection of solar energy is also very high, thus obtaining a high solar energy control capability. Cars are not suitable for affixing highly reflective architectural films, because this will cause strong reflection on the side window glass and affect the viewing of the rear mirror. There will also be strong glare on the glass that affects the driver’s driving, so generally car films The reproduction process uses vacuum aluminum plating and a composite layer of colored film to eliminate reflections, and relies on the rapid flow of air to take away the heat absorbed on the glass during car driving, thereby obtaining a non-reflective and functional glass. High thermal insulation capacity. With the continuous advancement of technology and technology, the films currently produced by magnetron sputtering process take into account the ideal of reducing visible light reflection and having high heat insulation.

4. Architectural films and automotive films have different requirements for rare metal content:

The gold content of cadmium, nickel and titanium in the car film cannot exceed 5%, and the architectural film cannot exceed 2.5%. Under this requirement, it meets the overall requirements of environmental protection and ecology, because the people driving the car are generally adults and healthy people, and it is impossible for people to People who live in cars for a long time, and building rooms include pregnant women, infants, and the elderly, sick and disabled, if the content of rare metals exceeds the standard, the radiation will have a certain impact on the growth and intellectual development of fetuses and infants, so the rare metal content of the building film Scientific standards should be met and strict standards of ecological and environmental protection should be followed.

5. The structure of the UV-absorbing layer of automobile film and architectural film is different:

Both films can block ultraviolet rays, but the ultraviolet blocking layer of the car film is a single layer of high-pressure plating. The ultraviolet blocking layer of the architectural film is a vacuum interlayer, which contains trace amounts of plutonium, which can absorb harmful spectrum and smooth out the spectrum. In the car film It only acts on UA in ultraviolet rays, and architectural films act on both UA and VB.

6. The colloids of automobile films and architectural films are different:

Automobile films use ordinary adhesive (HPR), while most architectural films use clear glue (CDF), while safety films use special adhesive with stronger adhesiveness. Due to different properties, the service life of automobile films is about 3-5 years, while the normal use of architectural membrane is 25 years.

7. The color systems of automotive film and architectural film are different:

Automotive film colors are black, natural color, green, etc., while architectural film colors are rich and suitable for various building and partition decorations.

8. The safety of automotive film and architectural film is different:

The safety and explosion-proof performance of the membrane is only related to its thickness. The thickness of the automotive film is 1.5MIL, while the thickness of the safety film is 4MIL-15MIL, which is the true safety and explosion-proof film.

9. The performance indicators of automotive film and architectural film are different:

Architectural membranes generally have higher performance requirements than automotive membranes, so in addition to understanding their light transmittance and heat insulation rate, you also need to understand their reflectivity, U-value, shading coefficient and other indicators.
