1. Ultraviolet blocking coefficient
The higher the ultraviolet blocking coefficient, the better the filtering effect of the film on ultraviolet rays, which can effectively prevent ultraviolet rays from damaging objects in the car and human skin.
2. Infrared blocking coefficient
The infrared blocking coefficient indicates the heat-shielding effect of the film. The higher the value, the better the heat-insulating effect. It can significantly reduce the temperature in the car and improve driving comfort.
3. Visible light transmittance
Visible light transmittance indicates the transparency of the film. High transmittance can ensure clear vision when driving, especially for the film on the front glass. Light transmittance oman number data should meet national standards.
4. Overall solar radiation blocking coefficient
The total solar blocking coefficient indicates the overall solar protection effect of the film. The higher the value, the better the comprehensive thermal insulation property of the film.
III. Selection of regular brands and channels
1. Brand reputation
Choose a well-known brand for better quality. Products from well-known brands have better guarantees in terms of performance, durability and after-sales service.
Pay attention to the performance indicators of automotive films
