Silicone oil, the English name is Silicone oil, CAS is 63148-62-9, the molecular formula is C6H18OSi?

 

It is a kind of polyorgano siloxane with different degree of polymerization chain structure. It is made from dimethyldichlorosilane by hydrolysis with water. The ring is cracked and rectified to form a low ring. Then the ring, the header agent and the header agent are used.

 

Silicone oil can be prepared by removing the low boiling matter from the mixture of various degrees of polymerization by vacuum distillation.

Main characteristics

 

Silicone oil has excellent heat resistance, electrical insulation, weather resistance, hydrophobicity, physiological inertia and small surface tension, in addition to a low viscosity-temperature coefficient, high compressibility) Some varieties also have radiation resistance.

 

Silicone oil has many special properties, such as oxidation resistance, high flash point, low volatility, non-corrosive to metals, non-toxic and so on.
