It is a polyorganosiloxane with a chain structure of different degree of polymerization. It is made from dimethyl dichlorosilane and hydrolyzed to obtain an initial polycondensation ring body. The ring body is cracked and rectified to obtain a low-ring body. A mixture of different polymerization degrees can be obtained by removing low-boiling substances through distillation under reduced pressure.


Uses: There are various viscosities. Has higher heat resistance, water resistance, electrical insulation and less surface tension. Commonly used as high-grade lubricating oil, shockproof oil, insulating oil, defoamer, release agent, polishing agent and vacuum diffusion pump oil. Methyl silicone oil is the most commonly used. In addition, there are ethyl silicone oil, methylphenyl silicone oil, nitrile-containing silicone oil, and the like. Wuhan silicone oil, edible silicone oil, medical silicone oil
