What is silicone?
Silicone, that is, an organosilicon compound, refers to a compound containing a Si-C bond and at least one organic group is directly bonded to a silicon atom, and it is customary to use an organic group and a silicon atom through oxygen, sulfur, nitrogen, or the like. The attached compound is also considered to be an organosilicon compound. 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. .

Silicone properties:
Temperature resistance


The silicone product is based on a silicon-oxygen (Si-O) bond. The bond energy of the C-C bond is 82.6 kcal/g molecule, and the bond energy of the Si-O bond is 121 kcal in the silicone. / gram molecules, so silicone products have high thermal stability, and the chemical bonds of molecules at high temperatures (or radiation) do not break or decompose. Silicone is not only resistant to high temperatures, but also resistant to low temperatures and can be used over a wide temperature range. Whether it is chemical or physical mechanical properties, it varies little with temperature.


Weather resistance


The main chain of silicone products is -Si-O-, which has no double bonds and is therefore not easily decomposed by ultraviolet light and ozone. Silicones have better thermal stability and resistance to radiation and weathering than other polymer materials. The service life of silicone in the natural environment can reach several decades.


Electrical insulation performance


Silicone products have good electrical insulation properties, and their dielectric loss, withstand voltage, arc resistance, corona resistance, volume resistivity and surface resistivity are among the best in insulating materials, and their electrical properties are affected by temperature and frequency. The impact is small. Therefore, they are a stable electrical insulating material and are widely used in the electronics and electrical industries. In addition to excellent heat resistance, silicone has excellent water repellency, which is a guarantee of high reliability in the use of electrical equipment under wet conditions.


Biological characteristics


Bioactive silicone is an essential nutrient for the human body. Silicones are important elements that make up human tissue and participate in metabolism. It is stored in every cell of the human body as a support for cell construction, and at the same time helps other important substances such as magnesium, phosphorus, calcium and the like to be absorbed. The human body can only continuously obtain silicone through food.


Scientists believe that silicones exist in humans in three main forms:


(1) Soluble silicone, accounting for 10% of the weight


(b) 30% in various cell matrices


(C) 60% used to synthesize protein, which means that the silicone we need every day is quite high.


If you want to maintain 5 years, 10 years or even 30 years of youth, it is especially important to consume 20-30 mg of silicone per day.


Low surface tension and low surface energy


The main chain of silicone is very compliant, and its intermolecular force is much weaker than that of hydrocarbons. Therefore, it is lower in viscosity than hydrocarbons of the same molecular weight, has weak surface tension, small surface energy, and strong film forming ability. This low surface tension and low surface energy are the main reasons for its multi-faceted application: hydrophobic, defoaming, foam stabilization, anti-sticking, lubrication, glazing and other excellent properties.


Silicone use:
Since silicone has these excellent properties, it has a wide range of applications. It is not only used as a special material for aviation, cutting-edge technology, and military technology departments, but also used in various sectors of the national economy. Its application has been extended to: construction, electrical and electronic, textile, automotive, machinery, leather and paper, chemical light industry, Metals and paints, medical and medical services, etc.
