The KDX metallic reflective thermal insulation automotive film adopts a robust thermal insulation approach based on the principle of "replacing absorption with reflection" —utilizing Kangdexin's dual-chamber, twelve-target magnetron sputtering production line to deposit precious metals such as silver and titanium in molecular form layer by layer onto an optical-grade PET substrate, creating an 11–12-layer dense thermal reflection structure.
This structure blocks solar radiation from entering the vehicle by means of the directional reflection of the metal layers within the near-infrared wavelength range, rather than absorbing the radiation into the Automotive Window Film before gradually heating the glass. Taking the S70 window as an example: it offers a visible light transmittance of 75%, a visible light reflectance of 9%, UV barrier performance of 99%, and a total solar radiation barrier rating of 54%; for the dark-colored S15/S20 side and rear windows, the total barrier rating ran…
