Methyl fluorosilicone oil, hydrogen fluorosilicone oil, amino fluorosilicone oil, hydroxy fluorosilicone oil and vinyl fluorosilicone oil are all different types of fluorosilicone oils, and they have certain differences in function and application areas. The following is a detailed introduction to the functional differences of these five types of fluorosilicone oils:



Methyl fluorosilicone oil
Functional features:

Methyl fluorosilicone oil is an oligomer composed of trifluoropropyl methylsiloxane, with the appearance of a colorless or light yellow transparent liquid.
After the introduction of trifluoropropyl, methyl fluorosilicone oil has the characteristics of corrosion resistance and solvent resistance, while maintaining the wide operating temperature range of silicone oil (-60~200℃).
It has low surface tension and low refractive index, and is suitable for use as a corrosion-resistant and solvent-resistant defoamer, lubricant, and grease.
In textile printing and dyeing, it is also a good choice for high-efficiency defoamers and fabric finishing agents.

Hydrogen fluorosilicone oil
Functional characteristics:

Hydrogen fluorosilicone oil is an organic silicon polymer composed of silane, siloxane, etc., and its fluorinated version may have similar chemical structure and properties.
It usually has excellent thermal stability, low surface tension and high surface activity.
These characteristics make hydrogen fluorosilicone oil widely used in many fields, such as lubrication, rust prevention, glass molding in high temperature environments, and as a surfactant and emulsifier.
However, the detailed functions and characteristics of hydrogen fluorosilicone oil may need to be determined according to the formulation and properties of the specific product.

Amino fluorosilicone oil
Functional characteristics:

Amino fluorosilicone oil introduces amino groups on the basis of fluorosilicone oil, thereby enhancing its softness and lubricity.
It can produce directional adsorption with carboxyl groups, hydroxyl groups, etc. on the surface of fabrics, reduce the friction coefficient between fibers, and is therefore widely used in the field of fabric softeners.
At the same time, amino fluorosilicone oil also retains the original water resistance, oil resistance and heat resistance of fluorosilicone oil.
It also has potential application value in polyurethane and resin modification.

Hydroxyfluorosilicone oil
Functional characteristics:

Hydroxyfluorosilicone oil is a colorless, odorless or light yellow transparent liquid, suitable for use as a structural control agent in the processing of fluorosilicone rubber.
It can effectively prevent the structuring phenomenon of fluorosilicone rubber and improve the processing performance and finished product quality of fluorosilicone rubber.
It may also have certain application potential in other fields such as coatings, adhesives, etc.

Vinyl fluorosilicone oil
Functional features:

Vinyl fluorosilicone oil is mainly composed of fluorosilicone polymers, and has excellent resistance to polar and non-polar solvents and oil.
It can be used for a long time in the range of -50~250℃, and has good corrosion resistance, weather resistance and electrical insulation properties.
Vinyl fluorosilicone oil is widely used in the production of fluorosilicone rubber products such as oil-resistant pipes, belts, sealing strips, sealing rings, and as raw materials for aircraft fuel tank seals, engine accessories, etc.

Summary

These five types of fluorosilicone oils have different focuses in terms of functions and application areas. Methyl fluorosilicone oil is known for its corrosion resistance, solvent resistance and wide operating temperature range; hydrogen-containing fluorosilicone oil is widely used in many fields due to its excellent thermal stability and surface activity; amino fluorosilicone oil performs well in the field of fabric softeners; hydroxyl fluorosilicone oil is an important auxiliary agent in fluorosilicone rubber processing; vinyl fluorosilicone oil is widely used in high-end fluorosilicone rubber products due to its high temperature resistance, oil resistance and corrosion resistance. When choosing to use, you need to choose the appropriate type of fluorosilicone oil according to the specific application scenario and needs.
