Changzhou Yapu New Material Co., Ltd., founded in 2008, is located in Wujin District, Changzhou City. It specializes in the research, development, production and marketing of electrochromic materials and electrochromic lenses. It has a complete set of core patented technologies and sustainability of the product. Update the strong technology and production strength of iteration.
More+Electrochromic lenses are similar in structure to sandwiches,When a small current is applied, two conductive glass will form an electric field to change the color of the discoloured material,top electrifying and carry out the reduction reaction inside the material.

Electrochromic lenses
The solid-state EC material developed by Yapu is essentially different from the common liquid crystal dimming film material in the market. Because the liquid crystal is naturally not resistant to low temperature and UV aging, it is not suitable for automotive applications. At present, only EC, gentex, Magna and so on have the world's ability to develop materials.
The solid state (gel state) EC material developed by Yapu has good safety performance. The glass is still bonded together after breaking, and no sharp debris will fall off.
From the performance parameter comparison table, we can see that the main parameters of Yapu EC lens are the same as those of the mainstream foreign manufacturers, and some parameters are better than others.
After nearly 20 years of research and development, Yapu core team has opened up its own technical path in the fields of advanced EC functional materials, high performance sealing materials, magnetron sputtering target materials, photosensitive control algorithm, production process and manufacturing equipment R&D and design, and established a complete technical system, production system and quality system. Through the system optimization, the product achieves high quality and low cost.
We independently developed EC membrane materials with high stability in physical and chemical properties and excellent performance, which are suitable for different applications. It has the following basic performance characteristics:
①Resistant to uv aging, no yellowing;
②High and low temperature resistance to extreme environment;
③Cyclic deterioration;
④The fastest discoloring speed is less than 0.5 seconds;
⑤The maximum test cycle life is over 5 million times.
The self-designed multi-target integrated magnetron sputtering coating machine can simultaneously deposit composite films of metal, TCO and dielectric targets on glass substrates, and prepare EC device film electrodes with specific transmittance, reflectivity and optical absorption requirements. Independent research and development of target materials and membrane structure ensures that the obtained thin film electrodes meet the requirements of physical, electrochemical and optical properties at the same time.
Using self-designed environmental light detection technology, the wavelength distribution of different vehicle light sources can be accurately identified, and the sensitivity of human eyes to different wavelengths can be corrected. At the same time, the unique DC step-down technology is adopted to minimize the energy loss and effectively suppress the temperature rise of the control circuit/device. Different control modules can be integrated in the control circuit according to the different needs of users to achieve the purpose of expanding functions.
Variable color lenses with different color, shape and response rate can be developed according to the user's needs, which can be applied to a variety of application scenarios. Based on deep technical strength, perfect R&D system and quality control system, it can provide guarantee for continuous cost reduction, performance improvement and cost reduction and efficiency enhancement for users.
As glass is the basic material of modern society, its application is more and more extensive, and people's demand for discoloration of glass is increasing day by day.
The application range of electrochromic EC lenses can cover all aspects of our residence, travel, entertainment and so on.For example, this Japanese concept car launched at the Tokyo Motor Show in 2017 integrates all the central control information into an arc-shaped car inner screen. The obstacle to mass production is the glare, which increases the difficulty for drivers to read.
Through years of systematic research and development, the company has opened up its own technological path in the fields of advanced EC functional materials, high performance sealing materials, magnetron sputtering target materials, photosensitive control, optical device design, production process and manufacturing equipment R&D and design, and established a complete technical system, production system and quality system. Through the system optimization, the product achieves high quality and low cost.
Companies and individuals now have 48 domestic and foreign authorized invention patents, 14 utility model patents, and 34 invention patents and utility model patents in applications; in recent years, they have won the titles of "National High-tech Enterprise", "Jiangsu High-tech Enterprise" and "Jiangsu High-tech Enterprise". Electronic anti-glare mirror has won the title of "Jiangsu High-tech Products". The company has obtained IATF 16949:2016 certification, and its terminal customers are several mainstream domestic vehicle manufactory.
