Properties
of organic silicone
Silicone products are
the basic structural units of silicon - oxide chain composed of the side chain
through the silicon atom is connected to a variety of other organic groups .
Therefore, the structure of the organic silicone products containing both
" organic group ", also contain " inorganic structure " ,
this particular composition and molecular structure so that it sets the
characteristics of organic and inorganic functionality in a Compared with other
polymers , silicone products, the most prominent performance are:
A. Electrical insulation properties
Silicone products have good electrical insulation properties, dielectric loss , resistance, voltage, arc resistance, corona , volume resistivity and surface resistivity of insulating materials are on the top , and their electrical performance is affected by temperature and frequency little effect . Therefore, they are a stable electrically insulating material , is widely used in electronics, electrical industries. Silicone addition has excellent heat resistance , but also has excellent water repellency , electrical equipment which is used under wet conditions with high reliability protection.

B. Physiologically inert
Silicone-based compounds are known in the least one active compound . They are extremely resistant to biological aging, and animal body no rejection , and has better anti- clotting properties.

C. Temperature characteristics
Silicone product is silicon - oxygen (Si-O) bond in the main chain structure , C-C bond energy of 82.6 kcal / mol , Si-O bond in the organic silicon is 121 kcal / mole , so the silicone products, high thermal stability

D. Weathering
Silicone products, the main chain -Si-O-, unparalleled key exists , it is not easy to be decomposed by ultraviolet light and ozone .
