4 Price Prediction

The feedstock styrene is fluctuating weakly, resulting in a lower cost center. Industry supply has decreased compared to the previous period, and downstream procurement is based on just-in-time demand, slowing the overall pace. In the short term, the PS market may experience narrow fluctuations. It is expected that the East China market will see transparent modified styrene at 6900-8000 yuan/ton.
