EVA (butadiene-butyl acrylate polymer) is a good packaging product, with its high-quality product packaging characteristics, good temperature resistance and preferential **, occupying more than 50% of the market share. It is currently the most widely used film material for solar cell packaging.
With the improvement of the development of the photovoltaic power generation economy and the implementation of energy conservation and emission reduction measures in various countries around the world, the photovoltaic industry continues to flourish. In 2021, the number of new global users reached 170GW, an increase of 28% year-on-year. In the future, with the introduction of policies around the world and the gradual improvement of the international energy system, the installed capacity of photovoltaics is expected to continue to increase [1]. The rapid development of the photovoltaic power generation industry has promoted the battery packaging film materials (POE) of EVA and polyolefin elastomers, and with the increasing consumer demand, its scientific research and development and production capacity building activities are very active, becoming one of the prospective industries in the new chemical materials industry.
EVA plastic films play an important role in solar modules. It is mainly used to bond photovoltaic panels, photovoltaic glass and side panels together. On the premise of ensuring the light transmittance of the components, it can protect the external water vapor, increase the service life of the solar module, maintain the battery module, and encapsulate it into a solar module that can export DC.
It is conjectured that in the context of carbon emission trading, the world's photovoltaic industry is entering a period of rapid growth, which will also generate abundant and stable demand growth for upstream and downstream raw materials. In the next three years, China's consumption demand for photovoltaic power generation EVA will increase by about 250,000 tons year-on-year. The growth rate of the supply-side structure is acceptable, but due to the relatively low quantity, it is still unable to meet the requirements of continuous growth, and the neutralization assumes that the supply and demand gap in the field in the next three years is about 150,000 tons, and the commodity ownership rate of EVA optoelectronic materials is still less than 50%.
In general, EVA high-voltage polyethylene thin-film photovoltaic has good development potential and broad development prospects. However, it is facing some tests, such as product upgrades, sales market acceptance, etc.
