Zhangzhou Qimei's PS plant has a total annual capacity of 350,000 tons, with the current overall operating rate at 50%. Suppliers are adjusting to market conditions, and sales performance is relatively stable. PriceSeek's analysis of PS indicates a bullish-bearish score of +1. The reduction in the operating rate of Zhangzhou Qimei's PS plant to 50% has significantly lowered capacity utilization, leading to a notable decrease in polystyrene supply. The relatively stable sales performance suggests that demand remains steady. With tightening supply and sustained demand, PS spot prices are expected to rise, which is favorable for the market. The score of +1 indicates a generally positive outlook, as the primary driver is supply contraction, but the absence of strong demand growth prevents it from reaching a major positive level.
