Silicone oil has excellent heat resistance, electrical insulation, weather resistance, hydrophobicity, physiological inertia and small surface tension, in addition to low viscosity-temperature coefficient, high resistance to compressibility) Some varieties also have radiation resistance. Silicone oil is a kind of polyorganosiloxane with different degree of polymerization and chain structure. It is made of dimethyldichlorosilane and water hydrolysis to obtain the initial condensation ring, ring by cracking, rectification to produce a low ring, and then the ring, the head agent, the catalyst put together to get a mixture of different polymerization degrees can be obtained, by vacuum distillation to remove the low boiling matter can be prepared silicone oil.
