According to the Commodity Analysis System of Shengyi Society, the styrene market saw a slight increase on the 17th. From a news perspective, international oil prices have fallen, with average support from the raw material side. The on-site supply is sufficient, supported by pre holiday stocking, and the on-site transactions are still acceptable. It is expected that the port inventory will increase in the future, and the possibility of a short-term rise followed by a decline in the styrene market is expected to increase.
