Silicone Chemicals-Outstanding Performance Of Silicone
Posted On 05/19/2020 07:05:27 by ritchiesilways

Organosilicon, that is, organosilicon compound, refers to a compound containing Si-C bond, and at least one organic group is directly connected to the silicon atom, and it is customary to often use oxygen, sulfur, nitrogen, etc. to make the organic group and silicon atom The connected compounds are also regarded as organosilicon compounds. Among them, polysiloxane composed of silicon-oxygen bond (-Si-O-Si-) as the skeleton is the most widely studied, most widely used and most widely used organosilicon compound, accounting for more than 90% of the total dosage .

The basic structural unit of silicone products is composed of silicon-oxygen links, and the side chain is connected to various other organic groups through silicon atoms. Therefore, the structure of silicone products contains both "organic groups" and "inorganic structures". This special composition and molecular structure make it combine the characteristics of organic matter with the function of inorganic matter. Compared with other polymer materials, the most
The outstanding performance is:

1. Temperature resistance
Silicone products are based on silicon-oxygen (Si-O) bonds as the main chain structure. The bond energy of CC bonds is 82.6 kcal / mole, and the bond energy of Si-O bonds is 121 kcal in silicones. / Mole, so the thermal stability of silicone products is high, and the chemical bond of the molecule does not break or decompose at high temperature (or radiation irradiation). Silicones are not only resistant to high temperature, but also low temperature, and can be used in a wide temperature range. Whether it is chemical properties or physical mechanical properties, changes with temperature are very small.

2. Weather resistance
The main chain of silicone products is -Si-O-, no double bonds exist, so it is not easy to be decomposed by ultraviolet light and ozone. Silicone has better thermal stability and resistance to radiation and weathering than other polymer materials. The service life of silicone in natural environment can reach several decades.

3. Electrical insulation performance
Silicone products have good electrical insulation properties, and their dielectric loss, voltage resistance, 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 very small. Therefore, they are a stable electrical insulation material and are widely used in the electronics and electrical industries. In addition to excellent heat resistance, silicone also has excellent water repellency, which is a guarantee of high reliability for electrical equipment used in wet conditions.

4. Biological characteristics
Bioactive silicone is an essential nutrient for the human body. Silicone is an important element that constitutes human tissues and participates in metabolism. It is stored in every cell of the human body and serves as a support for cell construction, while helping to absorb other important substances such as magnesium, phosphorus, and calcium. The human body can only obtain silicone through food.

Scientists believe that silicones are mainly present in the human body in three forms:

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

(2) Thirty percent exists in various cell substrates

(3) 60% is used to synthesize protein, which shows that the silicone we need every day is quite high.
If you want to stay young for 5 years, 10 years or even 30 years, it is especially important to consume 20-30 mg of silicone per day.

5. Low surface tension and low surface energy
The main chain of silicone is very flexible, and its intermolecular force is much weaker than that of hydrocarbons. Therefore, it has lower viscosity, weaker surface tension, lower surface energy, and stronger film-forming ability than hydrocarbons of the same molecular weight. This low surface tension and low surface energy are the main reasons for its many applications: hydrophobic, defoaming, foam stability, anti-sticking, lubrication, glazing and other excellent properties.

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