Silicone oil is a linear polysiloxane product that remains liquid at room temperature, and there are many types of silicone oil according to different classification criteria. Here's a closer look at silicone oils according to the different classifications:
1. Classified by chemical structure
Methyl silicone oil: also known as ordinary silicone oil, its organic groups are all methyl. Methyl silicone oil has good chemical stability, insulation, and hydrophobic properties, and is the most widely used variety of silicone oil.
Ethyl silicone oil: It is hydrolyzed and condensed into polysilic ether by various ethylethoxysilanes in the presence of hydrochloric acid, and then prepared by molecular rearrangement and vacuum fractionation. It is widely used as an insulating material in the electrical industry, precision instrument oil, hydraulic oil, special lubricating oil, etc.
Phenyl silicone oil: The product obtained after the substitution of part of the methyl group by the phenyl group can be divided into low phenyl silicone oil, medium phenyl silicone oil, high phenyl silicone oil, etc. according to the different phenyl content.
Other silicone oils: including methyl hydrogenated silicone oil, methyl phenyl silicone oil, methyl chlorophenyl silicone oil, methyl ethoxy silicone oil, methyl trifluoropropyl silicone oil, methyl vinyl silicone oil, methyl hydroxyl silicone oil, ethyl hydrogen silicone oil, hydroxyl hydrogen silicone oil, cyanide silicone oil, etc.
2. Classification by application:
Damping silicone oil: Silicone oil used for shock absorption and damping.
Silicone oil for diffusion pumps: Silicone oil for use in vacuum pumps.
Hydraulic oil: Silicone oil used in hydraulic systems.
Insulating oil: Silicone oil used for electrical insulation.
Brake fluid: Silicone oil used in the brake system.
3. Modified silicone oil
Amino-modified silicone fluids: basic ingredients for textile softening finishes.
Hydroxysilicone oil: It can be used as a structural control agent for the production of room-temperature silicone rubber and a chain extender for the synthesis of other products.
Hydrosilicone oils: have specific chemical properties and can be used in a variety of chemical reactions.
In the production and application of silicone oil, different kinds of silicone oil have different characteristics and uses. For example, methyl silicone oil is widely used in electrical, electronic, chemical and other fields due to its good chemical stability and insulation; Phenyl silicone oil has an important position in aviation, aerospace and other fields due to its high thermal and chemical stability. At the same time, with the continuous progress of science and technology and the continuous improvement of people's requirements for the performance of silicone oil, various new silicone oils have been developed to meet the needs of different fields.
