      Company profile

Zhejiang Dilong Photoelectric Material Co., Ltd is a new energy technology enterprise specializing in the research, development, production and sales of EVA film packaging materials for solar cells. The company is located in Lin'an, a beautiful national forest park city in the western suburbs of Hangzhou. The production base is located in Linglong Industrial Park, Lin'an City, 2 kilometers away from the Linglong exit of Hangzhou-Huizhou Expressway, 30 kilometers away from the provincial capital Hangzhou, and only 170 kilometers away from the scenic Huangshan Mountain in Anhui. The transportation is very convenient.

The company was established in 2009 with a registered capital of 30 million yuan. The existing standardized workshop of 20,000 square meters is planned to be implemented to form an annual production capacity of 360 million square meters of film that is compatible with 210/182 components.

Since its establishment, the company has cooperated with domestic and foreign universities and research institutes, and invested 3 million yuan to establish a product research and development center according to provincial standards, independent research and development, continuous innovation, research and development of new products, new technologies and new processes. The product quality is stable, and all its technical indicators have passed the testing requirements of TUV, UL and CQC certification, and obtained six utility model patent certificates and one invention patent certificate.

High light transmission and yellowing resistance solar cell EVA encapsulated corneal products won the Lin'an Science and Technology Development Plan project; solar cell EVA film and back layer protective film production technology transformation project was rated as Hangzhou's key industry (industrial and information technology special) project. In 2013, he participated in the formulation of the construction industry standard of the People's Republic of China: ethylene-vinyl acetate copolymer (EVA) film for building photovoltaic modules; in 2015, he participated in the formulation of the national standard of the People's Republic of China: vinyl acetate in ethylene-vinyl acetate copolymer for photovoltaic modules. Ester content test method Thermogravimetric Analysis (TGA); in 2018, participated in the formulation of Zhejiang Manufacturing Group Standard: ethylene-vinyl acetate copolymer (EVA) film for photovoltaic module encapsulation.


Development path
