Asia
In Asia, polystyrene prices during Q4’25 stayed mostly weak and moved in a narrow range. The market had enough supply, while demand stayed low. Producers continued running plants, which kept material easily available. Styrene costs changed from time to time, but they did not give strong support to polystyrene prices. Buyers from electronics and home appliance sectors bought only small quantities. Packaging demand was steady but not strong. Many buyers preferred to use existing stocks instead of placing new orders. Because of this, prices did not rise and stayed mostly flat to slightly lower during the quarter.
Europe
In Europe, polystyrene prices declined during Q4’25. Demand from major sectors such as electronics, appliances, and insulation stayed weak. Buyers were careful and delayed purchases due to slow business activity and year-end holidays. Supply remained comfortable as producers had enough raw material. This led to higher inventories, which pushed prices down further. Packaging demand provided some support, but stricter rules and a shift toward recycled materials reduced fresh buying. Exports helped limit the fall, but overall market sentiment stayed negative.
North America
In North America, polystyrene prices continued to fall during Q4’25. The market suffered from weak demand and high stock levels. Construction activity slowed, which reduced demand for expanded polystyrene used in insulation. Packaging demand showed mixed results, with stable online sales but weaker industrial use. Producers kept supply steady, while buyers avoided bulk purchases. Most buyers focused on short-term needs only, which kept pressure on prices throughout the quarter.
