The circular economy and regional collaboration have opened up a new chapter of high-quality development for the ethyl silicone oil industry

1. Regeneration technology solves the problem of resource utilization
The ethyl silicone oil industry has taken the lead in breaking through the bottleneck of waste oil recycling and utilization, and two mature regeneration processes have been applied on a large scale. For waste silicone oil from electrical equipment, it can be refined with adsorbents such as silica gel and activated alumina. After vacuum degassing treatment at 50-110℃, its original performance can be restored and the purity can reach the standard of new oil. For liquid waste silicone oil containing impurities, vapor extraction with hydrocarbon or chlorinated hydrocarbon solvents can effectively remove pollutants such as polychlorinated and polycyclic aromatic hydrocarbons. After vacuum drying to remove the solvent, it can be recycled. The recycling process has increased the resource recovery rate to over 90%, significantly reducing the reliance on virgin raw materials. Each ton of recycled products can save about 30% of the cost.

2. The effect of regional industrial clusters has become prominent
The domestic ethyl silicone oil industry has formed a distinct regional synergy pattern. The Yangtze River Delta and Pearl River Delta regions, leveraging their manufacturing cluster advantages, have gathered over 70% of their production capacity. They focus on high-end application fields such as electronics, automobiles, and construction, with products mainly being high-viscosity and special functional types. Taking advantage of the policy dividends of industrial transfer, the central and western regions have become emerging production bases, focusing on the supply of general products and raw materials, and filling the gaps in regional markets. A collaborative system of "high-end R&D + basic production + application implementation" has been formed among regions, reducing logistics costs by 15% and significantly enhancing the industrial response speed.

3. The demand from emerging markets continues to expand
The global market is showing a diversified growth trend, with emerging economies in Asia becoming the core of demand growth. Due to the accelerated infrastructure construction in countries such as India and Southeast Asia, the demand for ethyl silicone oil in the fields of building sealing and transportation equipment has increased by more than 12% annually. With the acceleration of industrialization, the African market has a strong demand for waterproof and sealing materials. It is expected that the market size will exceed 500 million US dollars by 2025. The rapid development of the automotive and electronics industries in South America has driven the demand for special lubricants and insulating materials, providing new space for the export of ethyl silicone oil.

4. The dual carbon goals lead industrial upgrading
Under the impetus of the dual carbon policy, the ethyl silicone oil industry is accelerating its green transformation. Progress has been made in the substitution of bio-based raw materials. The carbon footprint of products made from plant-based ethanol has been reduced by 40%, gradually replacing traditional petroleum-based raw materials. The promotion of solvent-free processes has reduced the industry's VOCs emissions by more than 50%. 30% of the production capacity has adopted supercritical fluid technology, and the residual organic solvents in the products have been reduced to below 10ppm. At the policy level, ethyl silicone oil, as a key product of strategic emerging industries, has received support in terms of research and development funds and tax incentives, which has encouraged enterprises to increase investment in green technologies. The industry as a whole is steadily developing towards high efficiency, low carbon and sustainability.
