Industry Overview - The chemical sector showed a weekly performance ranking of 5th with a change of 2.58% from December 15 to December 19, 2025, outperforming the Shanghai Composite Index by 2.55 percentage points and the ChiNext Index by 4.83 percentage points [1] Key Insights - The chemical industry is expected to continue its differentiated trend in 2025, with a focus on synthetic biology, pesticides, chromatography media, sugar substitutes, vitamins, light hydrocarbon chemicals, COC polymers, and MDI [1] Synthetic Biology - The arrival of a pivotal moment in synthetic biology is anticipated, driven by energy structure adjustments. Traditional chemical companies will face competition based on energy consumption and carbon tax costs, with a shift towards green energy solutions and integrated advantages to reduce costs [2] - Companies like Kasei Bio and Huaheng Bio are highlighted as leaders in the synthetic biology sector [1] Refrigerants - The third-generation refrigerants are expected to enter a high prosperity cycle starting in 2024, with supply entering a "quota + continuous reduction" phase. The demand for refrigerants is projected to grow due to the development of heat pumps and the cold chain market [2] - Companies such as Juhua Co., Sanmei Co., Haohua Technology, and Yonghe Co. are positioned to benefit from this trend [2] Electronic Specialty Gases - Electronic specialty gases are critical for the electronics industry, with high technical barriers and added value. The domestic market is facing a mismatch between rapid upgrades in wafer manufacturing and insufficient high-end electronic specialty gas capacity [2] - Companies like Jinhong Gas, Huate Gas, and China Shipbuilding Gas are expected to capitalize on the domestic substitution opportunities [2] Light Hydrocarbon Chemicals - The trend towards light raw materials in the olefin industry is becoming global, with a shift from heavy naphtha to lighter low-carbon alkanes like ethane and propane. This shift is characterized by lower carbon emissions and energy consumption [3] - Satellite Chemical is recommended for investment in the light hydrocarbon chemical sector [3] COC Polymers - The industrialization of COC/COP (cyclic olefin copolymer) is accelerating in China, driven by domestic companies achieving breakthroughs and the shift of downstream industries to domestic sources [4] - Akolai is identified as a key player in the COC polymer production segment [4] Potash Fertilizers - Potash fertilizer prices are expected to rebound as the industry enters a destocking cycle, with supply constraints due to Canpotex withdrawing new quotes and Nutrien announcing production cuts [5] - Companies like Yara International, Salt Lake Potash, and Cangge Mining are noted as leading firms in the potash sector [5] MDI Market - The MDI market is characterized by oligopoly, with demand steadily increasing due to the expansion of polyurethane applications. The supply structure is expected to improve as major producers like Wanhua Chemical and BASF maintain significant market shares [6] - Wanhua Chemical is highlighted as a key company to watch in the polyurethane sector [6] Price Tracking - The top five price increases this week included SBS (4.52%), PTA (3.04%), and others, while the largest decreases were seen in nitric acid (-14.29%) and sulfur (-5.06%) [6] Supply Side Tracking - A total of 168 chemical enterprises had their production capacities affected this week, with 6 new repairs and 3 restarts reported [7]
