Guotou Securities·2025-12-27 13:58Investment Rating - The report maintains an investment rating of "Outperform the Market - A" for the organic silicon industry [3] Core Insights - The organic silicon industry is experiencing a transformation characterized by supply-side optimization and unexpected demand growth in emerging sectors. The report highlights the industry's response to traditional market slowdowns and the potential for structural changes in supply dynamics [1][2][7] - The demand structure for organic silicon is shifting, with traditional sectors like construction declining in share, while emerging sectors such as photovoltaics and electric vehicles are expected to drive significant demand growth [24][27][30] Summary by Sections 1. Overview of Organic Silicon - Organic silicon, primarily polysiloxane, is a versatile chemical compound used across various industries due to its unique properties such as thermal stability and electrical insulation [10][11] 2. Supply Expansion Cycle and Industry Dynamics - China's organic silicon production capacity increased from 1.515 million tons in 2019 to 3.44 million tons in 2024, with a CAGR of 17.8%. The report notes that the supply expansion cycle is nearing its end, with limited new capacity expected to come online [15][16] - The industry is consolidating, with the top four companies projected to control 54.7% of the market by 2025, fostering a more orderly competitive environment [16][17] 3. Demand Structure Optimization - The apparent consumption of organic silicon in China grew at a CAGR of 11.3% from 2019 to 2024. The share of traditional construction applications is expected to decline from 33.1% in 2021 to 25.2% in 2024, while sectors like manufacturing and transportation are gaining share [24][27] 4. Emerging Demand Drivers - Significant demand increases are anticipated from three key emerging sectors: photovoltaics, electric vehicles, and composite insulators. For instance, the photovoltaic sector is expected to contribute an additional 140,000 tons of organic silicon demand in 2025 due to a 30% increase in solar cell production [30][35] - The report estimates that the electric vehicle sector will add approximately 66,000 tons of organic silicon demand in 2025, driven by the rising production of electric vehicles [30][35] 5. Investment Recommendations - The report suggests focusing on companies with upstream self-sufficiency in industrial silicon and energy advantages, as well as those with strong positions in high-value downstream products. Specific companies highlighted include: - Hoshine Silicon Industry (合盛硅业) with significant production capacity and market presence [38] - Xin'an Chemical (新安股份) known for its comprehensive product range and strong market position [38] - Dongyue Silicon Materials (东岳硅材) with integrated production capabilities across the silicon value chain [38]
