1. Biological properties
Bioactive silicone is an essential nutrient for the human body. Silicone is an important element in the composition of human tissues and in metabolism. It is present in every cell of the human body as a support for cell construction and helps the absorption of other important substances such as magnesium, phosphorus and calcium. The human body can only obtain silicone through food on a continuous basis.
Scientists believe that silicone exists in the human body in three main forms:
(i) Soluble silicone, which accounts for ten percent by weight;
(ii) Thirty percent exists in various cellular matrices;
Sixty percent is used to synthesize proteins, which suggests that our daily requirement of silicone is quite high.
If you want to maintain a youthfulness of 5 years, 10 years or even 30 years, it is especially important to consume 20-30 mg of silicone per day.
2. Temperature-resistant properties
Silicone products are silicone-oxygen (Si-O) bond as the main chain structure, C-C bond bond energy of 82.6 kcal/g molecule, Si-O bond energy in the silicone is 121 kcal/g molecule, so silicone products are thermally stable, high. Therefore, silicone products have high thermal stability, and the chemical bonds of molecules do not break or decompose under high temperature (or radiation exposure). Silicone can not only withstand high temperatures, but also low temperatures, can be used in a wide range of temperatures. Whether it is chemical properties or physical and mechanical properties, with the temperature change is very small.
3. Weathering properties
The main chain of silicone products is -Si-O-, no double bond exists, so it is not easy to be decomposed by UV light and ozone. Silicones have better thermal stability and resistance to irradiation and weathering than other polymer materials. Silicones have a service life of several decades in natural environments.
4. Low surface tension and low surface energy
The main chain of silicone is very smooth, and its intermolecular force is much weaker than hydrocarbons, therefore, it has lower viscosity than hydrocarbons of the same molecular weight, weaker surface tension, smaller surface energy, and stronger film-forming ability. This low surface tension and low surface energy is the main reason for its multifaceted applications: hydrophobicity, defoaming, foam stabilization, anti-sticking, lubrication, varnish and other excellent properties.
