Zenithnano offers an ultra-thin PET material featuring high infrared reflectance, high visible light transmittance and attractive appearance. Using the principle of metal magnetron sputtering, Zenithnano has developed a "triple-silver" process based on existing window films, which outperforms the traditional "single-silver" process. The maximum infrared reflectance can reach 95%, with visible light transmittance up to 75%. It blocks infrared rays to the maximum extent while maintaining visible light transmission. Based on research on metal properties, Zenithnano has developed heat-insulating window films in a variety of colors. Customers can select suitable infrared reflective film colors according to specific scenarios and personal preferences.
