Report Overview - Report Title: C3 Industry Chain Weekly Report - Report Date: August 17, 2025 - Report Institution: Guotai Junan Futures Research Institute 1. Report Industry Investment Rating - Not provided in the report 2. Core Views LPG Section - Short - term valuation is reasonable, and the market will move in a range. Domestic civil gas supply and demand remain loose, with prices showing weak and narrow fluctuations. Ether - post C4 prices are in an upward - trending pattern. In the next week, civil demand will remain seasonally weak, and the short - term boost to the overall chemical end's operating rate is limited [3]. Propylene Section - Supply and demand are tightening, and prices have certain support. Although the supply will increase after the restart of some devices, there is still a large supply - demand gap in Shandong in August and September, and price support is expected to remain [4]. 3.
