    The thermal insulation film absorbs infrared rays by the thermal absorbing adhesive coated on the surface of the transparent polyester film to achieve thermal insulation, and the thermal insulating properties is degraded with time. The Window Film Transmission Meter LS181 is used to test the thermal insulation effect of the thermal absorbing film.
    The development of window film
    
Since the introduction of the automotive window film, it has experienced four stages of dyeing film, metal reflective film, thermal absorbing film and intelligent spectrum selective film, and the thermal absorbing film belongs to the third generation.
    The thermal absorbing film absorbs infrared rays by the thermal absorbing adhesive coated on the surface of the transparent polyester film to achieve the purpose of thermal insulation, but the thermal absorbed by the thermal absorbing glue can easily reach saturation, and when the thermal absorbed by the thermal absorbing rubber is saturated, the thermal absorbing rubber will re-radiate the absorbed thermal into the car in the way of infrared rays, making people feel more hot.
    The ultraviolet blocking rate of the absorbing film can reach 90%-100%, and the infrared blocking rate is also about 30%-95%.
    How to test the insulation effect of the thermal absorbing film?
    Linshang Technology has a variety of window film transmission meter, and we have found that the infrared blocking rate of the 950nm is generally higher for thermal absorbing film. In the window film sales process, we recommend using the window film transmission meter LS181 to test the absorbing film, which can get better infrared blocking data.

    Of course, in addition to testing the infrared blocking rate, this instrument can also test the ultraviolet blocking rate of 365nm and the visible light transmittance of 550nm.
    The LS181
window film transmission meter uses a parallel light path source design to test automotive films and large thicknesses of glass. With an accuracy of ±2% (testing colorless, transparent and homogeneous material), it is ideal for demonstrations and tests in automotive 4S stores and window film stores.
