Low hydrogen silicone oil refers to compounds containing hydrogen siloxanes, also known as silanes or siloxanes. It is a type of organic silicon compound, consisting of a chain like or circular structure composed of silicon oxygen bonds and silicon carbon bonds. The term "low hydrogen" in the name of silicone oil indicates that this type of silicone oil molecule contains fewer hydrogen atoms.

Silicone oil can be divided into different types according to its molecular structure and functional characteristics. The three common types of silicone oil are:
Methyl Silicone Oil: Its molecules contain methyl groups (- CH3), making it the simplest type of silicone oil commonly used as lubricants, sealants, and adhesives. The low hydrogen content of methyl silicone oil gives it good heat resistance and chemical stability.

Phenol Methyl Silicone Oil: Based on methyl silicone oil, the introduction of a phenyl group (- C6H5) enhances the high-temperature and oxidation resistance of silicone oil, making it suitable for applications under high temperature conditions.

Vinyl Silicone Oil: Introduces a vinyl group (- CH=CH2) into the molecule, giving silicone oil better softness and elasticity. It is commonly used as a modifier for rubber and plastics, as well as for lubrication and protection.

Silicone oil has been widely used in many fields due to its excellent performance, such as:
Industrial field: As a lubricant, sealant, waterproof agent, anti adhesion agent, and demolding agent, it is used to increase the luster and smoothness of material surfaces, reduce friction and wear.

Medical field: Used in the production of medical silicone products, such as silicone implants, catheters, etc., widely used in medical equipment and plastic surgery.

Personal care products: As an ingredient in skincare products, they are used for moisturizing, lubricating, and improving texture.

Electronic products: used for heat dissipation, sealing, and insulation.

It should be noted that although silicone oil has superior performance in many aspects, it may have unsuitable applications in some cases. When using silicone oil, appropriate type and grade shall be selected according to specific requirements and characteristics.
