Some main performance indicators of automotive glass PE film
Oct 17, 2019
Visible light transmittance: referred to as light transmittance, is used to measure the percentage of visible light passing through the glass, the front film is generally more than 70%, the side back gear is generally 5%-60%, the lower the percentage, the light transmission The worse the ability, the darker the relative film color.
UV blocking rate: high quality automotive film, this indicator is generally not less than 98%, high up to 100%. The high UV blocking rate can effectively prevent people in the car from being exposed to excessive ultraviolet rays and burn the skin, while many inferior membranes do not have this indicator, or far below the 98% standard.
Infrared blocking rate: Infrared is also a part of sunlight. Most of the heat of light is transmitted through infrared rays. Compared with automotive glass film, the higher the percentage, the better the heat insulation effect.
Total thermal insulation rate: The total thermal insulation rate of professional thermal insulation film can generally reach 40%-79%. It is a comprehensive value derived from the various indicators of the glass film. Some merchants often confuse the concept and often use the concept of "infrared blocking rate" to impersonate "insulation rate". This is not correct.
Visible light reflectance: Unlike visible light transmittance, higher reflectivity reflects the illuminated light directly, similar to a mirror. The higher the reflectance, the stronger the privacy of the glass film and the better the heat insulation.
