1. Temperature resistance characteristics
General polymer materials are mostly based on carbon-carbon (CC) bonds as the main chain structure, such as plastics, rubber, chemical fibers, etc., while silicone products are based on silicon-oxygen (Si-O) bonds as the main chain structure. , The bond energy of the CC bond is 82.6 kcal/mole, and the bond energy of the Si-O bond is 121 kcal/mole in silicone, so the thermal stability of silicone products is high, under high temperature (or radiation exposure) The chemical bonds of molecules do not break or decompose. Silicone is not only resistant to high temperature, but also resistant to low temperature, and can be used in a wide temperature range. Whether it is chemical properties or physical mechanical properties, the change with temperature is very small, which is also related to the flexible helical structure of silicone molecules.

2. Weather resistance
The main chain of organic silicon products is -Si-O-, and there is no double bond, so it is not easy to be decomposed by ultraviolet light and ozone. In silicone products, the chain length of Si-O bonds is approximately one and a half times the chain length of C-C bonds. The longer chain length makes silicone have better thermal stability, radiation resistance and weather resistance than other polymer materials. The life span of silicone in natural environment can reach several decades.
 
3. Electrical insulation performance
Silicone products have good electrical insulation properties. 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 kind of stable electrical insulating materials, which 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 for high reliability of electrical equipment used in wet conditions.

4. Physiological inertia
Polysiloxane compounds are one of the most inactive compounds known. They are very resistant to biological aging, have no rejection reaction with the animal body, and have good anticoagulant properties.

5. Low surface tension and low surface energy
The main chain of silicone is very flexible, and this excellent flexibility is due to the basic geometric molecular configuration. Because the intermolecular force is much weaker than that of hydrocarbons, it has lower viscosity than hydrocarbons of the same molecular weight, weak surface tension, low surface energy, and strong film-forming ability. This low surface tension and low surface energy are the main reasons for its various applications: hydrophobicity, defoaming, foam stability, anti-sticking, lubrication, glazing and other excellent properties.
