From October 22 to 24, 2019, the annual meeting and exhibition of China Society of Automotive Engineering (2019saecce) with the theme of "automobile plus, collaborative innovation" opened in Shanghai as scheduled. Auto Cafe] will have a dialogue with several industry experts and leaders of auto enterprises to discuss the policies, technologies and trend of auto market in the current environment. The following is the interview record of Yao Jingyu, Minister of strategic planning department of seeper intermediate membrane: the intermediate membrane used by Yao Jingyu, Minister of strategic planning department of seeper intermediate membrane, laminated glass of automobile, full name of polyvinyl butyral in Chinese. We are headquartered in Japan, with the full name of "Shuishui Chemical Co., Ltd." and a history of more than 70 years. Production includes ordinary diaphragm, sound insulation membrane, heat insulation membrane, head up display wedge membrane, panoramic gradient intermediate membrane, and other high-performance diaphragm. The market share of seeper intermediate film in China is about 70%. The main customers are Fuyao Glass, Saint Gobain, AGC and other auto glass factories. The products are widely used in joint venture brands such as,,, and other independent brands such as GAC. First of all, it is a safety issue. The car requires that the front windshield must be laminated glass. In case of collision, the front windshield will crack like a spider web and attach to the middle membrane to prevent passengers from flying out and causing injury. Secondly, with the improvement of vehicle performance, we have developed many high-performance diaphragms. The sound insulation film can greatly reduce the noise and improve the comfort of the passengers in the car; the heat insulation film can greatly cut off the ultraviolet and infrared rays in the solar radiation and reduce the temperature in the car; the wedge-shaped film for head up display can make the image clear; the panoramic gradient middle film can make the car modeling more fashionable, and this scheme was first adopted. Generally speaking, it is to develop products suitable for future automobiles from the aspects of intelligence and environmental protection. For example, in summer, it needs to be insulated, and in winter, it needs to adapt to the environment to meet the needs of passengers; in the daytime, the skylight glass can be used for sunshade, and in the evening, it can become the starry sky, etc.; in the highway, it needs to be isolated from the wind noise, and in the tunnel, it needs to be isolated from the noise in the tunnel. China is the world's largest automotive consumer market, and Chinese consumers are also very willing to try new technologies. We hope that in the future, we can not only develop new technologies and create new business models according to the needs of Chinese consumers. At present, the raw materials are still from abroad, and the current stability of the materials is not very good. If the quality can be improved in the future, then we will also consider the domestic materials.
