In the field of chemical materials, silicone oil is attracting widespread attention due to its unique properties. Silicone oil, as a linear polysiloxane product, mainly includes methyl silicone oil and modified silicone oil. Among them, methyl silicone oil is the most common type with its excellent chemical stability, insulation, and hydrophobic properties. Modified silicone oil further optimizes its performance to meet various applications by replacing some methyl groups. Silicone oil has remarkable characteristics. It is a light - yellow, odorless, and safe chemical. It hardly reacts with other liquids but can be mixed with a variety of organic solvents, showing good adsorption. It also has heat resistance, electrical insulation, weather resistance, hydrophobicity, physiological inertness, and a low surface tension. It has a low viscosity - temperature coefficient, high compressibility, and some varieties even have radiation resistance. These properties make silicone oil widely used in many fields. In industry, it is often used as high - grade lubricants, shock - absorbing oils, insulating oils, defoamers, release agents, etc. In daily life, care products such as shampoos add emulsified silicone oil to improve hair lubrication. In the medical field, silicone oil also plays an important role. For example, in ophthalmic surgery, "vitrectomy + silicone oil tamponade in the vitreous cavity" can be used to treat patients with retinal detachment. Recently, the "Annual Production of 20,000 Tons of Silicone Oil and Deep Processing Project" of Zhejiang Tiansilicon New Materials Co., Ltd. has made significant progress. The main building of the project has been officially capped. Since its commencement in August last year, the pile foundation project has been completed, more than half of the civil construction has been finished, and the equipment procurement and installation are proceeding in an orderly manner. It is expected to enter the trial production stage by the end of this year. This project adopts a fully automated continuous production line and a DCS distributed control system to achieve closed - loop operation of the entire process, which not only greatly improves production efficiency but also achieves "zero discharge" of wastewater and ultra - low emission of waste gas. With a total investment of 225 million yuan, the project will become a key growth pole for the silicone new material industry in Tiantai County after it is put into production. In terms of market data, the market size of silicone oil in China reached 11.034 billion yuan in 2024, and the global market size was as high as 26.834 billion yuan. With the continuous progress of science and technology, the application of silicone oil in emerging fields will continue to expand, and the industry has a very broad prospect.
