[City, Date] Today, Hesheng Silicon Industry, a leading enterprise in the domestic silicone industry, announced that its 100000 ton per year ethyl silicone oil project located in Jiaxing, Zhejiang has officially started production. The total investment of this project is 1.2 billion yuan, and it adopts the independently developed "continuous catalytic polymerization process". The product purity reaches 99.8%, and the viscosity range covers 10-100000 cSt. It can fully replace imported products, marking a major breakthrough in China's high-end organic silicon materials field.


Technological breakthrough: filling the domestic gap and benchmarking performance against international giants
Ethyl silicone oil, as a special organic silicon material, is widely used in high-end fields such as aviation, new energy, and semiconductors due to its excellent temperature resistance (-70 ℃ to 150 ℃), dielectric properties, and compatibility with mineral oil. Previously, the global market had long been monopolized by international giants such as Dow Corning and Wacker, and domestic companies could only produce mid to low end products, with the high-end market relying on imports.


The project leader of Hesheng Silicon Industry stated, "We have improved the yield of monomer synthesis from 85% to 92% by optimizing the Grignard reaction catalyst system. At the same time, we have introduced molecular distillation technology to control the molecular weight distribution index (PDI) of the product within 1.3, reaching the international advanced level. ”According to a third-party testing report, the viscosity change rate of the ethyl silicone oil produced by it is only 5% at a high temperature of 150 ℃, which is better than imported products (8%), and can meet the harsh working conditions of wind power equipment, new energy vehicle battery modules, and other applications.


Market impact: Accelerated import substitution, cost reduction of 30%
With the advancement of the "dual carbon" target, the demand for weather resistant insulation materials in the new energy industry has surged. Taking wind power as an example, a single offshore wind turbine requires about 200 kilograms of ethyl silicone oil as the transformer insulation medium, but the previous import price was as high as 80000 yuan/ton, which restricted the industry's cost reduction space. After the Hesheng Silicon Industry project is put into operation, the domestic product price is expected to drop to 55000 yuan/ton, a decrease of 30%, which will directly promote the cost reduction of wind power and photovoltaic equipment.


We have signed long-term supply agreements with leading companies such as Goldwind Technology and CATL, and the first batch of 5000 tons of products will be delivered next month. "The marketing director of Hesheng Silicon Industry revealed that the company plans to expand its production capacity to 300000 tons in the next three years and develop high-end derivatives such as branched chain ethyl silicone oil to further seize global market share.


Industry evaluation: A key step towards independent and controllable industrial chain
Experts from the China Organic Silicon Industry Association pointed out that "ethyl silicone oil is an important indicator of a country's level of deep processing of organic silicon. The commissioning of the Hesheng project not only solves the bottleneck problem, but also promotes the coordinated development of the upstream and downstream industrial chains. It is expected that by 2025, the domestic market size of ethyl silicone oil will exceed 5 billion yuan, and the localization rate will increase from the current 35% to over 70%
