In December 2024, there were positive changes in the market price of EVA. Specifically, the ex - factory price of EVA petrochemical enterprises increased by 100 - 500 yuan/ton, driving the market price to adjust upward synchronously, with an increase range of 200 - 500 yuan/ton. This price adjustment was mainly influenced by the following factors:

Support from photovoltaic demand: Due to the favorable global photovoltaic demand, especially the early procurement by some overseas photovoltaic downstream enterprises, the demand in the EVA market was supported.

Market supply - demand situation: The inventory of EVA production enterprises was at a low level, and the effective utilization rate was relatively low. Moreover, the inventory pressure of traders was not high, and their anticipation of price increases was obvious.

In addition, in terms of the supply situation from January to October 2024, the total supply of EVA (including domestic production and imports) was 2.772 million tons, a year - on - year decrease of 145,000 tons, a decline of 4.97%. The shutdown and maintenance of some domestic plants and the relatively high cost of imports due to the high exchange rate also affected the market supply.

Overall, the market price of EVA showed an upward trend in December 2024, breaking the downward trend of market prices in December 2022 and 2023.
