Basic Introduction

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

Temperature resistance characteristics

Organic silicon products have a silicon oxygen (Si O) bond as the main chain structure. The bond energy of the C-C bond is 82.6 kcal/mole, and the bond energy of the Si O bond in organic silicon is 121 kcal/mole. Therefore, the thermal stability of organic silicon products is high, and the chemical bonds of molecules do not break or decompose at high temperatures (or radiation exposure). Organic silicon is not only resistant to high temperatures, but also to low temperatures, and can be used over a wide temperature range. Both chemical and physical mechanical properties have little variation with temperature.

Weather resistance

The main chain of organic silicon products is - Si O -, and there are no double bonds present, so they are not easily decomposed by ultraviolet light and ozone. Organic silicon has better thermal stability, radiation resistance, and weather resistance than other polymer materials. The service life of organic silicon in natural environments can reach several decades.

Electrical insulation performance

Organic silicon products all have good electrical insulation performance, and their dielectric loss, voltage resistance, arc resistance, corona resistance, volume resistance coefficient, and surface resistance coefficient are among the top in insulation materials. Moreover, their electrical performance is little affected by temperature and frequency. Therefore, they are a stable electrical insulation material widely used in the electronic and electrical industries. Organic silicon not only has excellent heat resistance, but also excellent water repellency, which ensures high reliability of electrical equipment when used under wet conditions.

Biological characteristics

Bioactive organic silicon is an essential nutrient for the human body. Organic silicon is an important element that constitutes human tissues and participates in metabolism. It exists in every cell of the human body, serving as a support for cell construction and assisting in the absorption of other important substances such as magnesium, phosphorus, calcium, etc. The human body can only continuously obtain organic silicon through food.

Scientists believe that organic silicon mainly exists in three forms in the human body:

(1) Soluble organic silicon, 10% by weight

(2) 30% present in various cell matrices

(3) 60% is used to synthesize proteins, which indicates that the amount of organic silicon we need every day is quite high.

If you want to maintain a youthful level for 5, 10, or even 30 years, it is particularly important to consume 20-30 milligrams of organic silicon daily.

Low surface tension and low surface energy

The main chain of organic silicon is very flexible, and its intermolecular forces are much weaker than those of hydrocarbons. Therefore, compared to hydrocarbons of the same molecular weight, its viscosity is lower, its surface tension is weak, its surface energy is small, and its film forming ability is strong. This low surface tension and low surface energy are the main reasons for its various applications: hydrophobic, defoaming, foam stability, anti sticking, lubrication, polishing and other excellent properties.
