The price of styrene has fluctuated after rising, with cost support still being adequate. However, the buying sentiment is generally moderate. The industry's supply remains relatively high, and downstream purchasing is driven by rigid demand, leading to significant supply and demand pressure. In the short term, the PS market may experience narrow-range consolidation.
