In modern chemical production, polydimethylsiloxane (PDMS) has become a key additive for improving product performance due to its unique molecular structure.
Jiujiang Deep Sea Technology's PDMS-100cs methyl silicone oil, as a linear polymer with moderate viscosity, demonstrates significant technical advantages in personal care, industrial lubrication, and electronic insulation fields due to its excellent physicochemical stability.

I. Core Physical Properties and Molecular Structure
Jiujiang Deep-Sea Technology's PDMS-100cs methyl silicone oil is a polymer composed of an inorganic silicon-oxygen backbone and methyl branches, exhibiting a completely transparent liquid state at room temperature. Its flexible molecular chains endow the product with excellent physical properties. Key parameters are as follows:
Appearance: Completely transparent liquid
Flash point (open cup): >326℃, possessing extremely high thermal stability and safety
Viscosity temperature coefficient: 0.60, meaning its viscosity is minimally affected by temperature fluctuations, maintaining stable performance even in extreme temperature environments
Solubility parameter: 7.4, readily soluble in aliphatic and aromatic hydrocarbons and various organic solvents
Surface energy: Possesses low surface energy characteristics, giving the product good spreadability and low surface tension.
II. Application Advantages of Jiujiang Deep-Sea Technology's PDMS-100cS
Superior Slippery Feel and Improved Touch
In personal care and cosmetic formulations, PDMS-100cS is a core ingredient for enhancing the user experience. It imparts a soft, velvety feel to the skin without producing a greasy residue. Due to its excellent distributability, it helps active ingredients spread evenly on the skin and hair surface. Simultaneously, this product has a significant "soap-removing" effect, effectively preventing foaming caused by friction during application and improving product quality. Precise Industrial Lubrication and Damping Properties
In industrial applications, its 100cS viscosity makes it ideal for lubricating elastomers, plastic bearings, and gears. Its high shear stability ensures that the molecular chains do not easily break down during mechanical operation, thus providing long-lasting lubrication protection. Furthermore, utilizing its high damping effect, PDMS-100cS is often used as a mechanical fluid and shock absorber to absorb system vibrations and extend the service life of precision equipment. Excellent Surface Finishing and Release Efficiency
Jiujiang Deep Sea Technology's PDMS-100cs has high water repellency and extremely low surface energy. In automotive, furniture, and metal polishing agents, as an active ingredient, it improves appearance and forms an easy-to-polish and weather-resistant protective film. Meanwhile, due to its non-stick properties with metals and plastics, it is also a highly efficient mold release agent in the production of various rubber and plastic products, ensuring a smooth surface and easy film formation of the finished product.
High-end Electrical Insulation and Chemical Stability
Thanks to its high dielectric strength and good thermal stability, 100cs methyl silicone oil is widely used in electrical insulating fluids and has low environmental hazards, low fire risk, and extremely low reactivity. This makes it the preferred high-performance medium in demanding chemical, power, and special processing industries.
III. Usage Guidelines and Industry Adaptability
Jiujiang Deep Sea Technology's PDMS-100cs silicone oil is very easy to use. Through standard emulsifiers and common emulsification techniques, it can be easily emulsified in water, meeting the needs of water-based formulations. In solvent-based applications, it has high compatibility with halogenated hydrocarbon propellants in aerosols and most hydrocarbon solvents.
Industry Application List:
Textile Printing and Dyeing: Used for fiber lubrication and smoothing, eliminating static electricity.
Defoaming Field: As a raw material for organosilicon defoamers, it is widely used in petroleum, chemical, and pharmaceutical processes.
Precision Polishing: Automotive paint protection, stain-resistant treatment for metals and leather.
