The photovoltaic grade EVA market shows a tight supply and demand pattern, and Chinese companies are accelerating production expansion.

EVA, the full name is ethylene-vinyl acetate copolymer, which refers to a polymer material copolymerized by ethylene and vinyl acetate (VA). It has excellent flexibility, elasticity, wear resistance, transparency, and impact resistance. It has characteristics such as durability and aging resistance, and is widely used in photovoltaics, plastics, shoe materials, agriculture, electricity and other fields. Among them, photovoltaic grade EVA is the EVA resin used in the production of solar cell packaging films in the photovoltaic field.

Solar cell adhesive film is an important material used to protect batteries, isolate air, and bond photovoltaic cells, photovoltaic glass, and backsheets. It accounts for about 4% of the cost of photovoltaic modules. The photovoltaic cell adhesive film prepared from photovoltaic grade EVA has the advantages of good heat resistance, strong adhesion, good sealing, good environmental protection, easy installation, low cost, high photoelectric conversion efficiency, etc., and has now become the photovoltaic packaging adhesive film. Market mainstream products.

According to the “China Photovoltaic Grade EVA Resin Market Feasibility Research Report 2023-2028” released by the Industrial Research Center, currently in China Against the background of the booming development of the photovoltaic industry, the continuous expansion of the photovoltaic module market has led to an increasing demand for EVA film. As a key raw material for manufacturing EVA film, the demand for photovoltaic-grade EVA has increased accordingly. According to data from the China Photovoltaic Association, national photovoltaic module production will reach 288.7GW in 2022, a year-on-year increase of 58.8%. Against this background, the domestic photovoltaic-grade EVA market demand will exceed 1.3 million tons in 2022.

From the production side, the current domestic companies with mass production capabilities of photovoltaic-grade EVA mainly include Levima New Material Technology, Ningbo Formosa Plastics Industry, Jiangsu Sailbon Petrochemical, Shanghai Haiyouwei New Materials, Zhejiang Rongsheng Petrochemical, Jiangsu Dongfang Shenghong, Ningxia Baofeng Energy, Fujian Gulei Petrochemical, Xinjiang Dushanzi Tianli High-tech, etc.

With the gradual release of production capacity of local enterprises, my country’s photovoltaic-grade EVA production continues to increase. According to data from China Chemical Information Weekly, my country’s total EVA production capacity in 2022 will be 2.15 million tons/year, with an output of approximately 1.68 million tons. From the analysis of market supply and demand, my country’s photovoltaic grade EVA market currently shows a tight balance between supply and demand.

In order to alleviate the tight supply situation, most domestic photovoltaic-grade EVA companies are actively expanding production capacity. For example, in September 2022, Dongfang Shenghong started construction of a new 200,000-ton photovoltaic-grade EVA project; in May 2023, Yangzi Petrochemical-BASF built a new 300,000-ton/ Annual photovoltaic grade EVA announcement; In May 2023, National Energy Group Ningxia Coal Industry’s 100,000 tons/year EVA project started; In March 2023, Guangxi Huayi Energy and Chemical Industry’s 2×200,000 tons/year kettle + tubular tail process EVA device project was announced .

Industry analysts said that the current domestic planned production capacity of photovoltaic-grade EVA has exceeded 4 million tons, and most of them are expected to It will be successfully put into production before 2025. In the future, as related projects accelerate, the supply level of my country’s photovoltaic-grade EVA market will continue to improve, and the industry development trend will be positive.
