High-purity phenyl silicone oil mass production breakthrough - Domesticization wave hits the semiconductor and medical aesthetics sectors

1. Technological peak: Super pure phenyl silicone oil overcomes "critical bottlenecks"
In the second quarter of 2026, the domestic specialty organic silicon field witnessed a milestone breakthrough - ultra-high purity phenyl silicone oil achieved large-scale stable production. Through a new solid acid catalysis and multi-stage molecular distillation coupling process, the core indicators of the product have achieved a leapfrog improvement: monomer purity reaches 99.99%, metal ion content is less than 1 ppb, volatile matter is as low as 0.3%, and the molecular weight distribution index (PDI) is precisely controlled within 1.05-1.2. Compared to traditional processes, this new route completely resolves the three industry pain points of batch color differences in high phenyl content products, residual rings, and insufficient thermal stability. The thermal decomposition temperature has stabilized at over 380℃, the refractive index precisely reaches the range of 1.52-1.55, and the key performance is fully comparable to the international top level. 

2. Semiconductor Boom: Chip Packaging and High-Performance Liquid Cooling Core Requirements
In the semiconductor industry, ultra-high-purity phenyl silicone oil is becoming a "must-have material" for advanced packaging and immersion liquid cooling. As the core component of high-refractive-index LED/Mini LED packaging glue, it has a transmittance of over 96.5% and a yellowing index of ≤2.2, which enables an increase in the brightness of the packaged device by 12%, extends the lifespan to over 50,000 hours, and increases the packaging yield from 92% to 98.5%. Facing the explosive growth of AI computing power, low-viscosity, high-thermal-conductivity phenyl silicone oil enters the immersion liquid cooling track for data centers. With a thermal conductivity of 0.22W/m・K and an insulation strength of 18kV/mm, it is suitable for high-density GPU clusters and can achieve long-term stability at 300℃, low volatility, and no coking, with a cooling efficiency that is 40% higher than traditional solutions. The consumption in the semiconductor field is expected to reach 28,000 tons in 2026, a year-on-year increase of 35%. 

3. Medical Beauty Upgrade: New Safety Standards Drive Replacement of High-End Raw Materials
In the field of cosmetics and personal care products, the "Safety Technical Specifications for Cosmetic Silicone Oils (2025 Edition)" has been fully implemented, forcing the industry to upgrade. The new regulations set the threshold for D4+D5 ring residue to be ≤ 10 ppm and purity to be ≥ 99.95%. Domestic high-purity cosmetic-grade silicone oils, with their advantages of refreshing smoothness, non-greasiness, high gloss, and strong extensibility, have quickly replaced imports. They are widely used in serums, creams, sunscreens, and makeup products, forming breathable protective films and having triple functions of moisturizing, protection, and antioxidation. In 2026, the penetration rate of the high-end cosmetics and personal care products market will reach 45.2%, driving the domesticization rate of domestic cosmetic raw materials to exceed 65%, and the annual market size to increase to 3.2 billion yuan. 

4. Industry Landscape: Domestic Replacement Accelerates, High-End Market Fully Breaks Through
With technological breakthroughs, the "import-led, low-end oversupply, high-end shortage" pattern in the phenyl silicone oil industry has been completely reversed. By 2026, the domestic self-sufficiency rate of high-end phenyl silicone oil will exceed 75%, an increase of 40 percentage points compared to 2022, and the import volume will continue to decline. The product structure is accelerating optimization: the proportion of general grade has dropped to 45%, while the proportions of high-purity, high-phenyl, and functionalized specialty grades exceed 55%. The downstream market is penetrating into high-precision fields such as semiconductors, photovoltaics, nuclear power, medical care, aerospace, etc., forming a "technological breakthrough - application expansion - scale expansion - cost reduction" virtuous cycle. It is expected that by 2028, China will become the world's largest producer and user center of phenyl silicone oil, with the global market share of high-end grades exceeding 40%, leading organic silicon materials to the top of the global value chain.
