Chemical ETF (159870) with a daily average trading volume of 2.115 billion, as the peak season in Q3 arrives, the trend of rising prices for chemical products is gradually becoming established.

In the news, the peak season for the chemical industry is approaching, and the trend of price increases for chemical products is gradually becoming established. Institutions point out that recent research and industry exchanges have identified the following products with upward pricing trends:

1. Refrigerants: The peak season for refrigerants usually begins in March. Recently, prices for all grades have been raised. Although refrigerant prices have already moved out of demand cycles and continue to rise, during peak season, the price increase pace is faster, and stock price catalysts are strongest. Additionally, based on current annualized refrigerant prices, valuations of refrigerant companies are generally below 15x, offering high cost-effectiveness.

2. Polyester Filament: Before this round of oil price fluctuations, joint production cuts were successfully implemented, and the industry chain transmitted prices smoothly. Profitability for filament companies has improved significantly. Although short-term oil price volatility caused stock price fluctuations, from a long-term perspective, under the dual internal competition of PTA and polyester filament, the sector’s elasticity is expected to continue rising.

3. Organosilicon: On February 28, a new round of anti-internal competition meetings was held in Ningbo. The latest resolution is to intensify emission reduction efforts: from March to May 2026, the industry’s overall emission reduction ratio will be increased from the previous 30% (December 2025 to February 2026) to 35%. The likely result of emission reduction is upward price movement. Recently, prices have continued to rise, with a major manufacturer’s quotes increasing by 1,500 yuan since March. Based on our industry surveys, companies are generally optimistic about profit recovery in organosilicon this year, and during peak season, prices per ton could double from current levels.
