Zhongling is a local window film brand in China, and its parent company, Dalian Accuride Nano Technology Co., Ltd., is one of the certified members of the International Window Film Association, with a number of core technologies and the world's most advanced vacuum magnetron sputtering and precision coating equipment, and the thermal insulation performance of its high-end products belongs to the first echelon of the industry.
 
Because Zhongling has high-end magnetron sputtering equipment, it can produce the most advanced magnetron sputtering film in the industry, which is also the main process used by Zhongling's window film products.
 
Mil (mil) is also known as milliinch, 1Mil = 0.0254mm, the thickness of the car window film is generally 1.5mil-2mil, and the car window film that exceeds 3 mil is rare. All window film thicknesses are above 3Mil, and some models can even reach 5Mil. Although a thicker window film can bring a good explosion-proof effect, its application surface is narrower. Due to the tighter window sealing strip of some models, the thickness of the car window film is too large, which may have a certain impact on the smoothness of the glass lifting, and long-term tight friction will also produce wave lines, affecting the driver's vision. In addition, the excessively thick window film increases the difficulty of construction for workers, and the skillful process of construction is also very demanding.
 
Thanks to magnetron sputtering technology, many of Zhongling's products perform well in visible light transmittance, solar blocking rate and ultraviolet blocking rate, etc., all products in the Zunyao Pro package, Zunyao package and zun package all use double silver 11-layer full magnetron sputtering process, the visible light transmittance of the front windshield glass can reach more than 70%, and the solar blocking rate is also more than 50%, however, the reflectivity in the front windshield model of the above three packages is higher, about 10%, which is not as good as foreign brands with the same process.
