Organosilicon: a "technological catalyst" in the field of chemical new materials
Organosilicon, a compound containing Si-C bonds and at least one organic group directly connected to silicon atoms, is like a shining star in the field of chemical new materials. With its unique properties and wide applications, it has become an important force in promoting technological progress and industrial upgrading, and is known as a "technology catalyst".


The unique structure of organic silicon materials endows it with many excellent properties. From a physical structure perspective, sufficient methyl groups on silicon atoms shield the high-energy main chain of polysiloxane, resulting in lower surface tension and surface energy of organosilicon materials. At the same time, the Si-O bond length is relatively long, the Si-O-Si bond angle is large, and the Si-O bond has a covalent bond characteristic of 50% ionic bond. These structural characteristics make organic silicon materials have both inorganic and organic properties, with high and low temperature resistance, electrical insulation, oxidation stability, weather resistance, flame retardancy, hydrophobicity, corrosion resistance, non toxicity, odorlessness, and physiological inertness.


Organic silicon materials play a crucial role in the aerospace industry. Due to its excellent high and low temperature resistance and radiation resistance, silicone sealant is widely used in the sealing and bonding of spacecraft, ensuring that spacecraft can operate normally in extreme environments. In the electronic and electrical industry, organic silicon materials are indispensable electrical insulation materials and packaging materials. Organic silicon insulating oil has good electrical insulation performance and heat resistance, and can be used for filling and insulation of equipment such as transformers and capacitors; Organic silicon encapsulation adhesive can protect electronic components from external environmental influences, improve the reliability and service life of electronic products.


In the field of architecture, organic silicon materials also have a wide range of applications. Organic silicone sealant has excellent weather resistance and waterproof performance, and can be used for sealing and waterproof treatment of buildings to prevent rainwater leakage and air infiltration. Organic silicon waterproofing agents can improve the waterproofing and durability of building materials, extending the service life of buildings. In addition, organic silicon materials can also be used in multiple fields such as textiles, automobiles, and healthcare. In the textile industry, organosilicon softeners can make textiles softer and smoother, improving wearing comfort; In the automotive industry, silicone lubricants can reduce the wear of mechanical components and improve the performance and reliability of automobiles; In the medical field, organic silicon materials have good biocompatibility and can be used to manufacture artificial organs, medical devices, etc.


In recent years, with the rapid development of emerging industries such as new energy, 5G, and ultra-high voltage, the demand for organic silicon materials has shown a rapid growth trend. China's organic silicon industry has formed a full chain coverage from upstream raw materials to high-end terminals. Leading enterprises have significantly enhanced their global competitiveness through vertical integration to reduce costs and horizontal expansion into high value-added fields such as semiconductors and new energy. At the same time, technological breakthroughs are also focused on the localization of electronic grade materials, functionalization of special sealants, and upgrading of environmentally friendly processes, promoting the continuous improvement of domestic substitution rate.


Organic silicon, as an important member in the field of new chemical materials, has made significant contributions to the development of modern technology and social progress with its unique properties and wide applications. In the future, with the continuous innovation of technology and the increasing demand, the application fields of organic silicon materials will be further expanded, and their development prospects are very broad.
