There are many types of silicone oil, each of which has a unique chemical structure and properties, so it is widely used in different silicone materials. The following are some common types of silicone oil and their application areas:
1. Classification of silicone oil
Dimethyl silicone oil:
It is the most common type of silicone oil, with excellent heat resistance, cold resistance, oxidation resistance and electrical insulation.
It is widely used in industrial-grade silicone materials, such as handmade soap molds, craft candle molds, resin craft silicone molds, etc.
Phenyl silicone oil:
The product obtained by replacing part of the methyl group with a phenyl group has the characteristics of low viscosity, excellent heat resistance, electrical properties and high flash point.
It is mainly used as an insulating impregnant for power capacitors to provide reliable insulation protection. In addition, it is also used in medicine, cosmetics, building materials and other fields.
Vinyl silicone oil:
It contains vinyl functional groups, has reactive activity, and can be used for crosslinking and modification of silicone rubber.
It is suitable for food-grade liquid silicone, platinum silicone, foaming silicone, electronic potting silicone, etc.
Hydrogen-containing silicone oil:
The molecule contains active hydrogen atoms, has low viscosity, and is often used as a diluent for silicone.
Widely used in pad printing silicone, screen printing silicone, printing silicone and other fields.
Hydroxyl silicone oil:
Contains hydroxyl functional groups and can be used as a structure controller for room temperature silicone rubber production and a chain extender for synthesizing other products.
Plays an important role in the synthesis of silicone rubber and other siloxane products.
Amino silicone oil:
Contains amino functional groups and has excellent softness and lubricity.
Mainly used as a basic component of textile softening finishing agents.
Modified silicone oil:
Including polyether modified silicone oil, carboxyl modified silicone oil, epoxy modified silicone oil, etc., with a variety of special properties.
Widely used in fiber processing, cosmetics, coatings, defoaming agents and other fields.
2. Application of silicone oil in silicone materials
Condensation type silicone: dimethyl silicone oil and the like are often used in condensation type silicone materials as an important raw material for industrial grade silicone.
Addition type silicone: vinyl silicone oil and the like are suitable for addition type silicone, such as food grade liquid silicone, platinum silicone, etc.
Pad printing and screen printing silicone: Hydrogen-containing silicone oil is often used as a diluent to adjust the viscosity of silicone and improve its processing performance.
Power capacitors: Phenyl silicone oil is widely used as an insulating impregnant for power capacitors due to its excellent electrical properties and heat resistance.
Textile softener: Amino silicone oil and the like are used as textile softening finishing agents to give fabrics a soft and lubricated feel.
In summary, there are many types of silicone oils, each with a unique chemical structure and properties, suitable for different silicone materials and fields. When choosing silicone oil, it is necessary to make comprehensive considerations based on specific application requirements and process conditions.
