Report Industry Investment Ratings - Propylene: ☆☆☆ [1] - Pure Benzene: ★★★ [1] - PX: ★★★ [1] - Short Fiber: ★★★ [1] - Methanol: ☆☆☆ [1] - PVC: ☆☆☆ [1] - Soda Ash: ★☆☆ [1] - PTA: ★★★ [1] - Plastic: ★★★ [1] - Styrene: ☆☆☆ [1] - Ethylene Glycol: ★☆☆ [1] - Bottle Chip: ★★★ [1] - Urea: ☆☆☆ [1] - Caustic Soda: ★☆☆ [1] - Glass: ★★★ [1] Core Viewpoints - The chemical market shows a complex situation with different products facing various supply - demand relationships and price trends. Some products are affected by factors such as new capacity release, downstream demand changes, and oil price fluctuations [2][3][5] Summary by Relevant Catalogs Olefins - Polyolefins - Propylene futures fluctuate narrowly with insufficient liquidity. Due to downstream device maintenance in Shandong and new capacity release, the market's ability to digest propylene is limited, and prices lack upward momentum [2] - Polyolefin futures' main contracts fluctuate narrowly. For polyethylene, supply pressure increases, inventory accumulates, and although downstream demand warms up, the supply - demand situation lacks substantial improvement. For polypropylene, upstream inventory transfers to the middle, demand is weak, and the trading atmosphere is dull [2] Pure Benzene - Styrene - After a sharp rise in night - time oil prices, the pure benzene price recovers. Its weekly supply and demand both decline, and the port inventory accumulates slightly. There is an expected seasonal improvement in the third - quarter mid - to - late stage and pressure in the fourth quarter. It is recommended to operate on the monthly spread [3] - Styrene futures' main contract fluctuates narrowly. The cost support strengthens as oil prices rise, but the supply - demand situation remains weak with high supply and accumulated port inventory, and stable downstream demand [3] Polyester - PX and PTA prices rise in the morning and fall slightly in the afternoon due to oil price support. PX fundamentals have limited drive, and PTA continues to accumulate inventory with weakening processing margins and basis. Mid - term processing margins have a repair drive but depend on downstream demand recovery [5] - Ethylene glycol's downstream demand is stable, and port inventory fluctuates at a low level. It faces supply changes due to device maintenance and restarts. Short - term oil price strength provides positive support [5] - Short fiber and bottle chip prices follow raw material fluctuations. Short fiber's processing margins decline, and its demand is in the off - season, but there is mid - term positive expectation. Bottle chip has stable inventory under low - start conditions, and over - capacity restricts its processing margin repair [5] Coal Chemical Industry - Methanol futures fluctuate narrowly. Coastal MTO device operation is not high, and the port accumulates inventory seasonally. Domestic supply is sufficient, and downstream demand changes little. The market is likely to fluctuate within a range [6] - Urea futures' main contract opens high and closes low. Local agricultural demand is ending, downstream demand is weak, and production enterprises accumulate inventory. The market is likely to operate within a range in the short term [6] Chlor - Alkali - PVC prices fall at the end of the session. Supply decreases due to enterprise maintenance, and social inventory accumulates. Domestic demand is weak, but external demand is expected to improve. Long - term prices are unlikely to rise significantly [7] - Caustic soda prices are weak. Chlor - alkali comprehensive profit improves, and device operation increases. Alumina demand provides support, but non - aluminum demand is average. Long - term supply pressure remains, and prices are expected to be under pressure [7] Soda Ash - Glass - Soda ash futures prices fall at the end of the session. Inventory decreases, and production increases slightly. The photovoltaic industry continues to cut production, and there is supply - demand pressure after the sentiment fades [8] - Glass prices fall at the end of the session. Spot sales weaken, industry profit recovers slightly, and processing orders are weak. In the long - term, without supply reduction, glass prices are unlikely to rise significantly [8]
