On November 13, 2025, Shanghai, China - As the global silicone industry transitions towards high-end and refined direction, ethyl silicone oil (CAS number 63148-61-8), as an important branch of silicone materials, is steadily growing in market size at an average annual rate of 8%. According to industry data, the global market size of ethyl silicone oil has exceeded 5 billion US dollars by 2025, with China, as the world's largest producer and consumer, accounting for over 40% of the global market share.


Technological breakthrough: Low volatility, high-purity products become mainstream
Ethyl silicone oil is widely used in fields such as electrical insulation, precision instrument lubrication, mechanical friction components, etc. due to its excellent lubricity, dielectric properties, and chemical corrosion resistance. In recent years, with the rapid development of industries such as electronics and healthcare, the market has increasingly stringent performance requirements for ethyl silicone oil. For example, in the field of electronic packaging, traditional ethyl silicone oil is prone to device performance degradation due to its high volatility, while low volatility, high-purity ethyl silicone oil has become a must-have in the industry.


Yunnan Nengtou Silicon Material Technology Development Co., Ltd. (hereinafter referred to as "Yunneng Silicon Material") recently announced that its independently developed "low ring ethyl silicone oil" has achieved large-scale production, with an annual production capacity of 5000 tons. This product optimizes the polymerization process to reduce the ring content to below 0.1%, reduces volatility by 60% compared to traditional products, and meets environmental regulations such as REACH and RoHS in the European Union. At present, the product has entered the supply chain of enterprises such as CRRC Zhuzhou Electric and Huawei, and is used for high-speed railway motor insulation and 5G base station heat dissipation materials.


Application Expansion: Comprehensive Penetration from Industrial to Consumer Fields
The application scenarios of ethyl silicone oil are accelerating from traditional industrial fields to consumer fields. In the cosmetics industry, ethyl silicone oil is widely used as an anti UV additive and defoamer in skincare products, shampoo, and other products due to its good lubricity and breathability. For example, the "Zero Sense" sunscreen launched by an international brand contains ethyl silicone oil derivatives as its core ingredient, which can achieve long-lasting waterproofing without clogging pores.


In the medical field, the application of ethyl silicone oil is also noteworthy. The "ultra-low temperature resistant ethyl silicone oil" developed by Xinyuan Chemical (Shandong) Co., Ltd. can maintain stable performance at -100 ℃ and has been used to manufacture lubricating coatings for medical catheters and artificial heart valves. In addition, in the textile industry, ethyl silicone oil, as a soft finishing agent, can significantly improve the hand feel and waterproof performance of fabrics, and is widely used in outdoor clothing and home textile products.


Policy driven: Green production becomes industry consensus
With the tightening of global environmental policies, the ethyl silicone oil industry is facing the challenge of green transformation. The "Action Plan for High Quality Development of New Materials Industry in the 15th Five Year Plan" released by the Ministry of Industry and Information Technology of China clearly states that by 2030, the energy consumption per unit output value of organic silicon materials needs to be reduced by 20%, and the waste recycling rate needs to be increased to over 90%. In this context, enterprises such as Yunneng Silicon Materials have increased the recovery rate of waste silicone oil in the production process to 85% and reduced energy consumption per ton of product by 15% by introducing automated production lines and closed-loop recycling systems.


Expert opinion: Professor Liao Jun from the School of Materials Science and Engineering at Wuhan University pointed out that "the competition in the ethyl silicone oil industry has shifted from scale expansion to technological iteration and green production. In the future, products with low volatility, high purity, and biodegradability will dominate the market
