(August 12, 2026) The domestic organosilicon functional materials sector continues to heat up. As the core crosslinker for additive silicone rubber and an important synthetic intermediate for various modified silicone oils, hydrogen-containing silicone oil, with rapid expansion in new energy, computing electronics, and photovoltaic industries, continues to release market demand. Domestic companies have made further breakthroughs in key indicators such as high purity, low volatility, and batch stability.

The molecular chains of hydrogen silicone oil contain active Si-H bonds and rely on silicon hydrogenation to achieve crosslinking and grafting modification. They are widely used in textile waterproofing agents, paper release agents, electronic potting adhesives, photovoltaic encapsulation silicone rubber, and are also fundamental raw materials for the production of modified silicone oils such as polyethers, phenylsyl, and epoxy oils, earning the nickname "industrial intermediate" of organosilicon. Industry data shows that by 2026, domestic demand for hydrogen-containing silicone oil is expected to exceed 120,000 tons, with a compound annual growth rate of 6-8%. The proportion of high-hydrogen grades in new energy and electronics manufacturing continues to rise.

In recent times, industry pain points have mainly been the large fluctuations in batch sizes of high-purity products, residual hydroxyl groups that easily cause platinum catalyst poisoning, high volatile content, and long-standing dependence on imports for high-end grades. By 2026, many domestic companies have completed process optimization, effectively reducing small molecule residues through catalyst system upgrades, by-product resource recovery, and improved distillation and purification processes. Low-hydroxyl hydrogen silicone oil achieves stable mass production, meets export REACH and K-REACH overseas compliance requirements, and is suitable for liquid silicone rubber, electronic potting, and AI liquid cooling material preparation scenarios.

On the downstream side, demand for high-performance silicone rubber has surged in new energy vehicle seals, photovoltaic module packaging materials, data center immersion cooling media, and flexible electronic components, directly driving the procurement volume of high-end hydrogen-containing silicone oil. Traditional textile and coatings industries are also upgrading toward low VOC and high weather resistance, forcing raw materials to improve product consistency and environmental performance.

Industry insiders analyze that fluctuations in upstream metallic silicon raw materials remain the main uncertainty in the industry, while the incremental dividends from downstream high-end manufacturing will drive the industry from purely competing on capacity to focusing on controllable purity, customized grade development, and green production processes. In the future, hydrogen-containing silicone oil and ultra-low volatility specialty grades will become key areas for domestic enterprises, further narrowing the gap with overseas leaders and accelerating the domestic substitution process of key silicone intermediates.
