Summary of the Conference Call on the Organic Silicon Industry Industry Overview - The conference focused on the organic silicon industry, highlighting its positive outlook under carbon emission constraints, which is expected to lead to price increases and a revaluation of the sector [1][2]. - The organic silicon industry is experiencing a continuous improvement in supply-demand dynamics, with stable growth in traditional sectors such as electronics, construction, and textiles, alongside rapid growth in new sectors like photovoltaic adhesives and lithium battery adhesives [1][2]. Key Insights and Arguments - **Demand Growth**: The projected growth rate for organic silicon consumption in China from 2025 to 2027 is estimated at 8% to 8.8%, indicating a robust growth trajectory [2][12]. - **Supply Constraints**: The organic silicon production capacity in China accounts for over 70% of global capacity, with significant capacity expansion expected to slow down, leading to limited new capacity releases in the coming years [2][16]. - **Price Recovery**: The price of organic silicon intermediates has risen from 11,000 CNY per ton in November 2025 to 14,000 CNY per ton by the end of January 2026, marking a nearly 27% increase [3][21]. - **Utilization Rates**: The capacity utilization rates are projected to improve from 70.58% in 2025 to 81.61% by 2027, indicating a recovery in the industry [5][19]. Sector-Specific Demand Analysis - **Construction**: The construction sector is expected to stabilize, with organic silicon consumption projected at 42.95 million tons by 2027, supported by improving housing sales and renovation demand [7][12]. - **Electronics**: The electronics sector is anticipated to see an 8% to 10% demand growth, driven by the increasing use of photovoltaic adhesives and domestic high-performance battery adhesives [9][11]. - **Manufacturing**: The manufacturing sector's demand is expected to grow due to investments in high-voltage power transmission and updates to electrical grid equipment [10][14]. - **Emerging Applications**: New applications in sectors such as medical, 3D printing, and transportation are expected to drive additional demand for organic silicon products [10][11]. Export and Import Dynamics - **Export Growth**: Organic silicon exports are projected to reach 559,000 tons in 2025, with a year-on-year growth of 2.4%. Key export destinations include South Korea (17.3%) and India (15.1%) [14][15]. - **Import Dependency**: The import dependency for organic silicon is expected to decrease to 3.7% by 2025, indicating a strengthening domestic production capacity [18]. Policy and Market Implications - The cancellation of export tax rebates starting April 1, 2026, is expected to increase export costs but may also encourage a shift towards higher value-added products [15][22]. - The industry is expected to benefit from the exit of overseas competitors, such as Dow Chemical, which will create opportunities for domestic companies to fill supply gaps [18][22]. Recommended Companies - Key companies to watch in the organic silicon sector include: - **Hesheng Silicon**: Leading in integrated production capabilities from industrial silicon to organic silicon [22][23]. - **Xingfa Group**: Notable for its comprehensive organic silicon capacity and integration with other chemical sectors [23]. - **New安股份**: Recognized for its complete organic silicon product line and strategic focus on high-end market segments [23]. - **Dongyue Silicon**: Strong in both upstream and downstream processing capabilities [24]. Conclusion - The organic silicon industry is poised for a recovery phase, driven by stable demand growth in traditional and emerging sectors, alongside a tightening supply environment. The overall sentiment is optimistic, with expectations of price stability and gradual increases in utilization rates [19][22].

各位领导、各位投资者，大家下午好，欢迎收听长江大化工组织的有机硅专场交流会议。 这次，也主要跟各位领导更新一下有机硅。特别是前端的中间体，DMC 这个环节，当前 的一些供需的一个展望，以及对未来反内卷的一些想法。针对有机硅这个环节，我们团队 应该也是市场最先推荐的，在 24 年的下半年就跟大家提示了这个行业面临的这个潜在的 供需再平衡的一个机会。有机硅这个产品，它为什么最近关注度这么高？或者说这一年来 各个机构也都纷纷的投入一些研发的、研究的这么一个力量，原因就在于它非常符合当前 化工板块讲的这么一个大逻辑。 分析师 1: 第一个，东升西落，海外特别是欧洲的装置。因为能源成本的一个提高，他们在全球范围 内的竞争力有所下滑，在跟国内一些大厂的这个内卷之中，他们处于一个比较劣势的一个 地位。出现了一些装置的一个关停，有机硅也是陶氏在英国的装置，目前也是低产后续准 备关停。其次，就是在过去的两到三年内，特别是 22 年到 24 年化工经历了上一轮景气周 期后，大部分的产能，各个企业家们他们对于未来的景气先行外推，把自己的这个赚的钱 作为这个扩产的这么一个资金。 这么一个成果了。这个跟今年的长丝，包括 PTA 也是比 ...
