    What is silicone oil?

    Silicone oil generally refers to a linear silicone product that remains liquid at room temperature and is generally classified 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 of its organic groups methyl. The 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.


    Dimethyl silicone oil has a variety of excellent characteristics, so it has been widely used in various sectors of industrial and agricultural production, defense industry, scientific research and medical and health departments. It is widely used in demoulding, defoaming, damping, shockproof, rolling, dustproof, waterproof, high and low humidity.


(1) The lubricity of silicone oil is not good, especially the friction of steel steel friction pair is poor.

(2) Silicone oil has a large thermal expansion coefficient (probability of overpressure).

(3) The gas solubility is large (it is difficult to design a gas seal device).
