(August 5, 2026) Recently, the market for silicone intermediates has continued to recover. As the core crosslinking agent for additive silicone rubber and a key synthetic raw material for modified silicone oil, hydrogen-containing silicone oil has attracted increasing market attention. Benefiting from downstream industries such as new energy vehicles, electronic packaging, and new textile materials, the domestic supply and demand structure for hydrogen silicone oil has changed significantly, with the industry accelerating its iteration toward high purity, stable batches, and green processes.

Hydrogen-containing silicone oil, relying on its active Si-H bonds within the molecule, can act as a crosslinking agent to participate in silicon hydroaddition reactions, producing liquid silicone rubber, silicone gel, electronic potting adhesives, and LED encapsulants; It can also be used as a base intermediate to synthesize polyether-modified silicone oil and alkyl-modified silicone oil; At the same time, it can form a film at low temperatures and is used as a waterproof and anti-fouling agent for fabrics, stone, and building materials, serving as a key functional raw material bridging the organosilicon industry chain. Within the industry, there are two main categories: high-hydrogen silicone oil and low-hydrogen silicone oil: high-hydrogen silicone oil has strong crosslinking activity and is mostly used in silicone rubber systems; Low-hydrogen silicone oil reacts gently and is widely used as a daily chemical additive, paint leveling agent, and textile softening finishing fields.

From a market perspective, upstream DMC raw material prices will fluctuate in 2026, supporting the cost side of hydrogen-containing silicone oil, while domestic mainstream specifications of hydrogen-containing silicone oil prices will remain at high levels and fluctuate in the market. Market research data shows that the global high hydrogen silicone oil market maintains a compound annual growth rate of about 7.7%, with stronger growth momentum in the domestic market. In addition to stable demand in traditional textiles, leather, and coatings, new energy and electronic information have become new growth engines. In scenarios such as new energy vehicle battery seals, energy storage insulation materials, upstream raw materials for AI server immersion cooling media, and semiconductor electronic potting materials, stringent requirements are set for low hydroxyl impurities, batch consistency, and active hydrogen stability. Demand for high-end hydrogen silicone oil is rising rapidly, and some high-purity grades are experiencing supply shortages.

Currently, domestic hydrogen silicone oil production capacity is sufficient, but product structure is clearly differentiated. Competition in the market for general products is fierce; High-purity, low-impurity grades suitable for electronics and new energy have high technical barriers and have long relied heavily on imports. In recent years, domestic silicone companies have continuously tackled challenges, optimizing synthesis and post-processing processes, reducing residual hydroxyl groups, strictly controlling viscosity and hydrogen content fluctuations, accelerating the process of domestic substitution.

Industry technology development shows three clear trends: First, products are upgrading toward high purity and narrow molecular weight distributions to meet the stringent usage requirements of electronic and medical-grade silicone rubber; Second, the number of customized products is increasing, with differentiated hydrogen content and viscosity specifications developed for different downstream sectors, adapting to various working conditions such as modified synthesis, waterproofing, and silicone rubber crosslinking; Third, green production process iterations reduce by-products, lower emissions of the three wastes, and comply with domestic and international environmental regulations and export compliance requirements such as REACH.

Industry analysts say that in the medium to long term, as new energy, semiconductors, and high-end new materials industries continue to expand, the market space for hydrogen-containing silicone oil will further open up. For manufacturers, relying solely on price competition for generic products is unsustainable. They need to focus on high-end niche segments, strengthen process control, stabilize batch quality, and improve compliant supporting facilities to seize the dual opportunities of domestic substitution and foreign trade exports. On the downstream procurement side, it is necessary to distinguish between the performance differences of high and low hydrogen silicone oils and select products reasonably based on actual application scenarios such as silicone rubber curing, fabric waterproofing, and modified synthesis, to avoid production losses caused by improper raw material selection such as product curing or waterproof failure.
