my country’s EVA resin production technology is basically mature and the market size is gradually expanding

EVA resin refers to an ethylene derivative using ethylene and vinyl acetate (VA) as raw materials, with a VA content of less than 40%. As one of the downstream products of ethylene, EVA resin has become the fourth largest ethylene series polymer after low density polyethylene (LDPE), linear low density polyethylene (LLDPE), and high density polyethylene (HDPE). Compared with other ethylene derivatives, EVA resin has the advantages of non-toxic, soft, low temperature resistance, impact resistance, excellent optical properties, etc., and has a wide range of applications.

At present, the EVA resin production process has gradually matured and can be roughly divided into solution polymerization, medium pressure suspension polymerization, high pressure continuous bulk polymerization, emulsion polymerization, etc. Among them, the high-pressure continuous bulk polymerization method has become the mainstream production process in the industry due to its advantages of low cost and high production efficiency. The high-pressure continuous bulk polymerization method can be further subdivided into kettle method, tubular method, etc. according to different reactors. At present, the kettle method accounts for the largest proportion of the overall production capacity, reaching 63.97%, due to its advantages such as high accuracy, fast reaction speed, and stable product quality.

my country’s EVA resin industry chain has basically matured. The upstream of the industrial chain is mainly raw material providers, providing ethylene, vinyl acetate and other raw materials; the midstream is mainly the EVA resin production industry, responsible for the production and manufacturing of EVA resin; the downstream is mainly the application field, EVA resin is used in functional shed films, packaging films, Foaming materials, photovoltaic films, wires and cables, and injection molded products are widely used.

From the perspective of the downstream market, photovoltaic film has become the largest application field of EVA resin, accounting for 33.94%; followed by foaming materials, accounting for 29.73%; wires and cables ranked third, accounting for 18.26% .

According to the “2023-2028 EVA Resin Industry Market In-depth Research and Investment Prospects Forecast Analysis Report” released by the Industrial Research Center, the recent In the past few years, my country’s energy structure has been gradually adjusted, the photovoltaic market has continued to develop, and the market demand for EVA resin has grown accordingly. In addition, EVA resin has excellent elasticity and can be used to make various cushioning materials, padding materials, etc., and the market demand has further increased. Against this background, the scale of my country’s EVA resin market is gradually expanding. From 2019 to 2022, my country’s EVA resin market size will increase from 20.11 billion yuan to 25.49 billion yuan, with an average annual compound growth rate of 8.22%.

From the perspective of import and export, my country’s EVA resin is highly dependent on foreign countries, and import volume continues to grow. According to data released by the General Administration of Customs, in 2022, my country’s EVA resin import volume will be 1.2024 million tons, an increase of 85,700 tons compared with 2021, and a year-on-year increase of 7.67%. However, as Chinese companies continue to expand production scale and EVA resin output gradually increases, the market’s dependence on foreign countries may gradually decrease in the future.

Industry analysts said that at this stage, my country’s largest EVA resin companies mainly include Levima Xinco, Sierbon Petrochemical, and Yanshan Petrochemical, Beijing Organic Plant, Formosa Plastics Group, etc. As China’s production capacity structure continues to upgrade, some small-scale EVA resin companies with backward production technologies may be eliminated, and the market will gradually move closer to leading companies. The EVA resin market concentration is expected to be further improved in the future.
