近期有机硅价格上涨

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].
