有机硅行业专家会议 20251123 摘要 有机硅行业通过减产应对需求疲软，11 月会议决定减产 30%，旨在提 升 DMC 价格至 13,500-14,000 元/吨，但实际执行效果受前期减产失 败影响，需关注监督机制的有效性。 成本端支撑有机硅价格，工业硅枯水期电价上涨增加成本，下游客户对 13,200 元/吨的高位报价持观望态度，询单成交量未达预期，上游厂商 需观察下游接受度。 本次会议企业参与度高，和盛董事长亲自牵头是关键因素，多晶硅收储 消息也产生积极影响，但前期企业常规检修后复产，可能影响减产计划 的实际执行。 传统需求如房地产下滑影响建筑密封胶需求，但新能源汽车、电池密封 胶等新兴领域带来增长点，有机硅皮革作为替代品具有市场潜力。 鲁西化工战略重点是产业链下游延伸和发展高端产品，恒业成和云南能 投也在拓展下游产品线，表明行业向高附加值方向发展。 国内有机硅需求可能下降，企业将开拓海外市场，欧盟碳关税促使蓝星、 陶氏等外资企业逐步清退海外产能，以国内产能为主。 预计 2026 年第一季度，有机硅行业将通过控制库存（45 天以内）来维 持供需平衡，DMC 报盘价约为 13,200 元/吨，利润区间在 ...

Investment Rating - The industry rating is "Overweight" (maintained) [6] Core Views - Recent price increases in organic silicon intermediates, particularly DMC, are attributed to rising costs of raw materials and supply constraints due to production halts at a major facility in Shandong. This has led to improved profitability for the sector. The supply of organic silicon is expected to remain limited in the medium term, while demand from sectors such as electronics, new energy vehicles, and photovoltaics is anticipated to grow. Additionally, favorable policies in the real estate sector may stabilize demand in traditional areas. The contraction of overseas production capacity is also beneficial for exports of organic silicon, indicating an improvement in the supply-demand dynamics and a potential recovery in industry sentiment [9][28]. Summary by Sections Industry Overview - From July 21 to July 25, 2025, the basic chemical industry saw a weekly increase of 4.03%, ranking 8th among all Shenwan first-level industries. The top five stocks by weekly increase were: Shangwei New Materials, Henghe Precision, Poly United, Gaozheng Minbao, and Subote. Conversely, the top five stocks by weekly decline were: Pioneer New Materials, Dadongnan, Qide New Materials, Brothers Technology, and Zhongyida [6][12]. Subsector - Organic Silicon - As of July 25, 2025, the price of organic silicon intermediate DMC reached 12,500 CNY/ton, an increase of 11.6% compared to the previous week, with the price spread rising by 26.2%. The continuous rise in the price of raw material metallic silicon has provided cost support for organic silicon. The supply side is tightening due to the production halt of a major enterprise in Shandong, leading to a temporary supply-demand imbalance. Previously, organic silicon companies faced prolonged low-price conditions, resulting in widespread losses. The current positive interplay between costs and supply has strengthened market pricing sentiment [11][15]. Price Trends of Related Products - The prices of related organic silicon products have followed the upward trend of intermediate prices. As of July 25, 2025, the prices were as follows: 107 glue at 13,000 CNY/ton (up 8.3%), raw rubber at 13,500 CNY/ton (up 9.8%), precipitated mixed rubber at 13,500 CNY/ton (up 5.5%), and dimethyl silicone oil at 14,500 CNY/ton (up 3.6%) [11][21].

Report Industry Investment Rating - Industrial silicon: Cautiously bullish [3] - Polysilicon: Cautiously bullish, but need to be aware of correction risks [8] Core Viewpoints - For industrial silicon, with positive macro - factors, improved supply - demand fundamentals, and price increases in downstream products, the industrial silicon price has room for further growth if it is benchmarked against the full cost [3]. - For polysilicon, after the continuous increase in spot prices, they have stabilized. The futures price is above the full cost of most enterprises, and there may be room for growth if considering the recovery of storage, merger, and acquisition funds. In the medium - to - long - term, it is suitable to buy on dips [8]. Market Analysis Industrial Silicon - **Futures Market**: On July 22, 2025, the industrial silicon futures price hit the daily limit. The main contract 2509 opened at 9345 yuan/ton and closed at 9655 yuan/ton, a change of 5.98% from the previous settlement price. The position of the main contract 2509 was 380961 lots, and the number of warehouse receipts was 50053 lots, a decrease of 88 lots from the previous day [1]. - **Supply Side**: The spot price of industrial silicon rose. For example, the price of East China oxygen - passing 553 silicon was 9600 - 9800 yuan/ton (up 200 yuan/ton), and the price of 421 silicon was 9800 - 10100 yuan/ton (up 200 yuan/ton) [1]. - **Consumption Side**: Affected by the strong drive of industrial silicon on the cost side and the supply concerns caused by an incident at a Shandong organic silicon factory, the prices of organic silicon products increased across the board. For example, the market price of DMC rose to 11600 - 12500 yuan/ton, an increase of about 1200 yuan/ton [2]. Polysilicon - **Futures Market**: On July 22, 2025, the main contract 2509 of polysilicon futures hit the daily limit, opening at 45880 yuan/ton and closing at 49105 yuan/ton, with a closing price change of 8.99% from the previous trading day.
