The automotive thermal insulation film currently on the market is divided into a heat absorbing film and a reflective film from the principle of heat insulation. Different films have a unique transmittance for light sources of different wavelengths. Therefore, we need to choose the right window tint checker when testing.
The heat absorbing film absorbs infrared rays by the heat absorbing adhesive coated on the surface of the transparent polyester film to achieve heat insulation, and the reflective film is a metal or nano ceramic material on the transparent polyester film to reflect infrared rays. For thermal insulation purposes. Different films have a unique transmittance for light sources of different wavelengths. Therefore, we need to choose the right window tint checkers when testing.
The difference between the heat absorbing film and the reflective film
The heat absorbing adhesive of the heat absorbing film can absorb heat energy (infrared rays in the solar spectrum), but the heat absorbed by the heat absorbing gel can easily reach saturation. When the heat absorbed by the heat absorbing gel is saturated, the heat absorbing rubber will regain the absorbed heat. Radiated into the car in the far infrared, making people feel hotter. The reflective film reflects the infrared rays outside the vehicle, and there is no problem of secondary radiation, thereby fundamentally solving the problem of heat insulation.
Linshang Technology has 11 years of experience in the window tint checkers industry. Based on years of experience, we have found that the heat absorbing film has a higher infrared blocking rate at 950 nm, while the reflective film has a higher infrared blocking rate at 1400 nm.
Therefore, when selling the thermal insulation film, if it is necessary to show the better infrared barrier performance of the thermal insulation film, we recommend that customers confirm the type of thermal insulation film before buying a meter. Here we are going to introduce the customer to a LS110H window tint checker for reflective film.
LS110H window tint checker application
The LS110H window tint checker uses a 1400nm infrared LED light source, which can be applied to various occasions through the split design of the main and auxiliary machines during testing. For more product information, please refer to "LS110H Window tint checker".
