What is the chemical name of silicone oil?

Silicone oil generally refers to a linear silicone product that remains in a liquid state at room temperature. Generally divided into methyl silicone oil and modified silicone oil. The most commonly used silicone oil-methyl silicone oil, also known as ordinary silicone oil, has all organic groups as methyl groups. Methyl silicone oil has good chemical stability, insulation and good hydrophobic properties. It is obtained by hydrolysis of dimethyldichlorosilane with water to obtain a polycondensation ring, and the ring body is obtained by cracking and rectifying to obtain a low ring body, and then the ring body, the heading agent and the catalyst are put together to be condensed to obtain each. A mixture of different degrees of polymerization can be obtained by removing low boilers by distillation under reduced pressure.
