Silicone, i.e., an organosilicon compound, refers to a compound containing the Si-C bond and having at least one organic base that is directly connected to the silicon atom. It is also customary to treat compounds that connect organic bases to silicon atoms through oxygen, sulfur, nitrogen, etc. as organosilicon compounds. Among them, polysiloxanes composed of silicon-oxygen bonds (-Si-O-Si-) are the most widely studied and most widely used organosilicon compounds, accounting for more than 90% of the total dosage.
Due to the unique structure of organic silicon, it has the properties of inorganic materials and organic materials. It has the basic properties of low surface tension, small viscosity coefficient, high compressibility and high gas permeability. It also has excellent properties such as high temperature resistance, electrical insulation, oxidation resistance, weather resistance, flame retardancy, water repellency, corrosion resistance, non-toxicity, tastelessness and physiological inertness. It is widely used in aerospace, electrical and electronic, construction, transportation, chemical industry, textile, food, light industry, medical and other industries, where silicone is mainly used for sealing, bonding, lubrication, coating, surface activating, demoulding, defoaming , anti-foaming, waterproofing, moisture-proofing, inert filling, etc. With the continuous growth of the number and variety of organic silicon, the application field has been continuously expanded to form an important product system unique to the chemical new materials industry. Many varieties are irreplaceable and indispensable for other chemicals.
Organic silicon is also involved in the metabolism of organisms, usually in the form of CH3(SiOH)3. Silicone plays an important role in the body's functions and is directly related to the absorption of minerals. The average human body has about seven grams of silicon, far more than other important minerals, such as iron. Iron and silicon are essential elements in the human body and play an important role in maintaining a normal metabolism.
