Zhejiang Zhengxin Photovoltaic Technology Co., LTD.（ZXEVA) is specialized in solar photovoltaic research and new materials development, production, sales and service.
Zhengxin（ZXEVA) was founded in January 2011. With investment of around $RMB2.5 billion, we are planning to establish over 20 unique production lines to produce EVA film, and to reach the annual target of 5,000 million square meters. We hope to become a famous international EVA film manufacturer within three years .
The founder and our R&D team start to do the research programme of EVA film with the support of professors and experts from several famous Universities in 2003. In the past few years, we have done great contributions to Chinese EVA film development.
From 2011, we have been got ISO 9001, SGS and TUV certifications successfully. We commitment to our quality management systems, environmental safety, and rigorous adherence to the health and safety of our employees.
Now the core product (Z1261) of ZX is manufactured based on more than eight years customer feedback. ZX will continue to do innovation, and timely development of superior performance, cost-effective products to meet the requirements of customers from all over the world.
Our mission is: "Under the scientific management system, to keep researching and developing, to improve product performance and service life of photovoltaic products, to provide greater value for our customers and the whole community, and to become the one of the best leading suppliers of solar photovoltaic materials in the world. "
Our mission is : "honest and trustworthy, fair and legal, scientific management, quality first."
