[0002] Silicone oil usually refers to linear polysiloxane products that remain in liquid state at room temperature. It is generally divided into two categories: methyl silicone oil and modified silicone oil. Silicone oil has many special properties, such as low temperature viscosity coefficient, high and low temperature resistance, oxidation resistance, high flash point, good insulation, no corrosion to metal, non-toxicity, etc. Among various silicone oils, methyl silicone oil is the most widely used and the most important variety of silicone oil, followed by methyl phenyl silicone oil. Various functional silicone oils and modified silicone oils are mainly used for special purposes.
