Basic introduction


The basic structural unit of silicone products is composed of silicon and oxygen chain, side chain is connected with other various organic groups through the silicon atom. Therefore, in silicone products structure which contains " the organic group ", and " containing inorganic structure ", characteristics, composition and molecular structure of this special so that its set of organic and inorganic function in a body. Compared with other polymer materials, the most outstanding performance of silicone products is:


Temperature characteristic


Silicone products based on silicon and oxygen ( Si-O ) key as the backbone structure, C-C bond energy of 82.6 kcal / mol, Si-O bond in silicon is 121kcal / mol, so the thermal stability of silicone products high, high temperature ( or radiation ) molecular chemical bonds are not broken, no decomposition. Silicone is not only resistant to high temperature, and low temperature resistance, can be used in a wide range of temperature. Both the chemical properties and physical mechanical properties, temperature variations are small.


Weather resistance


Silicone products backbone for - Si - O -, no double bond exists, so it is not easy to be decomposed by ultraviolet and ozone. Silicone is better than other polymer material thermal stability and resistance to irradiation and weathering ability. The service life of up to the natural environment in the next decades silicone.


Electrical insulating properties


Organic silicon product has good electrical insulating properties, the dielectric loss, voltage resistance, arc resistance, corona resistance, volume resistivity and surface resistivity are come out in front in the insulating material, and their electrical properties by temperature and frequency is very small. Therefore, they are a stable electrical insulating materials, are widely used in electronics, electrical industry. Silicone has excellent heat resistance, excellent water repellency, this is the use of electrical equipment with high reliability assurance in wet conditions.


Biological characteristics


The biological activity of silicone is one of essential nutrients. Silicon is an important element in the human tissue and the new supersedes the old. In every cell of the body, as the cells to construct support, and help other vital substances such as magnesium, phosphorus, calcium absorption. The human body can only through the food kept getting silicone.


Scientists think that silicone mainly exists in three forms in the human body:


(1 ) soluble silicone, accounted for 10% of the weight of the


(2) thirty percent exists in a variety of cell matrix


(3) 60% for the synthesis of proteins that we owe our daily silicone is quite high.


If you want to stay for 5 years, 10 years or so 30 years young, silicone 20-30 mg daily intake of silicone is particularly important.


Low surface tension and low surface energy


Organic silicon main chain is very soft, the intermolecular force than hydrocarbons is much weaker, therefore, compared with the same molecular weight hydrocarbons of low viscosity, surface tension, the surface can be small, film forming ability. The low surface tension and low surface energy is the main reason why it won many applications: hydrophobic, defoaming, foam stability, viscosity, lubrication, glazing the excellent performance.
