(1) the classification of silicone oil with different viscosity, non-toxic, odorless, non corrosive, non combustible polysiloxane liquid and oily substances. Methyl silicone oil is one of the main varieties of silicone oil, by changing the polysiloxane polymerization degree and organic radical species, or silicone with other organic copolymer can be prepared with a waterproof, anti adhesion, demolding, defoaming and other basic characteristics of silicone oil. There are many varieties of silicone oil, which can be divided into two categories: linear silicone oil and modified silicone oil.

(2) silicone oil products and application of silicone oil has many special properties, such as small viscosity temperature coefficient, high and low temperature resistance, anti-oxidation, high flash point, low volatility, insulation good, low surface tension, the metal without corrosion, non-toxic. Because of these properties, silicone oil is applied in many aspects and has excellent results. In all kinds of silicone oil, silicone oil is the most widely used, is the most important silicone oil, followed by methyl phenyl silicone oil. All kinds of functional silicone oil and modified silicone oil are used for special purpose.
