ShinEtsu KF-96H-1000000cs is an ultra-high viscosity silicone oil engineered as a high damping fluid for systems that demand controlled motion, stable resistance, and long-term mechanical reliability. As a 1m cst silicone fluid based on dimethylpolysiloxane, it delivers a smooth and consistent user experience by providing uniform drag force and predictable energy dissipation. Its clear and inert nature allows clean handling and compatibility with sensitive assemblies, supporting stable performance under repeated motion cycles and prolonged mechanical stress.

• Ultra-High Viscosity - ShinEtsu KF-96H-1000000cs exhibits a nominal kinematic viscosity of approximately 1,000,000 mm² per second at 25°C, positioning it firmly as an ultra-high viscosity silicone oil. This viscosity level enables the fluid to act as an effective vibration damping medium, generating strong internal resistance without the need for solid additives. The thick, slow-flowing behavior supports controlled motion in confined mechanical spaces where conventional lubricants cannot provide sufficient damping force.

  
  

• Thermal Stability - The fluid maintains stable viscosity across a wide temperature range, with a flash point equal to or exceeding 300°C and a pour point near –50°C. Experimental data shows limited viscosity fluctuation under thermal cycling, allowing the high damping fluid to preserve consistent resistance in both low-temperature and elevated-temperature environments. This stability ensures predictable damping behavior during long-term thermal exposure.

  
  

• Shear Stability - As a shear-stable lubricant, ShinEtsu KF-96H-1000000cs demonstrates strong resistance to molecular degradation under mechanical stress. Shear testing confirms minimal viscosity loss even under continuous oscillation and repeated motion. This property is critical for heavy-duty vibration dampener systems, where sustained shear forces would otherwise reduce damping efficiency over time.

  
  

• Chemical Inertness - The silicone oil remains chemically inactive at ambient conditions and shows negligible reaction with alkaline solutions up to approximately 10 percent concentration and acidic solutions up to roughly 30 percent concentration. This inert behavior prevents corrosion, chemical breakdown, or material incompatibility, ensuring long-term stability when in contact with metals, elastomers, and engineered plastics.

  
  

• Low Surface Tension - With surface tension significantly lower than water and many synthetic oils, the fluid spreads evenly across contact surfaces. This property enhances wetting behavior and allows the formation of a continuous damping film in micro-clearance environments. Uniform surface coverage contributes to smooth resistance and reduces the risk of stick-slip effects in kinetic energy absorber systems.

  
  

• Electrical Insulation - ShinEtsu KF-96H-1000000cs provides reliable dielectric performance with high electrical resistivity and stable insulating behavior under thermal load. These characteristics allow the fluid to function in environments where damping and electrical insulation are required simultaneously, without introducing conductive pathways or compromising electrical safety.

• Automotive Systems - In automotive assemblies, ShinEtsu KF-96H-1000000cs serves as a vibration damping medium in components requiring controlled motion and noise suppression. Its ultra-high viscosity enables effective absorption of kinetic energy generated by mechanical movement, improving operational smoothness and long-term stability during repetitive motion.

  
  

• Industrial Machinery - Within industrial machinery, this high damping fluid supports motion control in mechanically loaded systems. The shear-stable lubricant behavior ensures that resistance remains consistent under continuous operation, helping to stabilize mechanical response and reduce vibration-induced wear across extended service intervals.

  
  

• Precision Instruments - Precision instruments benefit from the predictable flow behavior of this 1m cst silicone oil, which enables fine motion control without backlash or sudden resistance changes. The fluid supports smooth adjustment and stable positioning, while its chemical inertness protects sensitive internal components from degradation.

  
  

• Electronics Assemblies - In electronic assemblies, the silicone oil contributes both mechanical damping and electrical insulation. Its dielectric stability supports use near sensitive circuits, while its thermal resistance helps maintain consistent performance in compact housings exposed to internally generated heat.

  
  

• Damping Mechanisms - As a heavy-duty vibration dampener, ShinEtsu KF-96H-1000000cs is used in systems designed to dissipate mechanical energy gradually. The fluid converts kinetic motion into controlled viscous resistance, enhancing system stability and extending the operational lifespan of damping structures.

  
  

• Sealing Systems - In sealing-related assemblies, the fluid supports controlled movement while maintaining compatibility with elastomeric materials. Its low surface tension and chemical stability help ensure consistent sealing performance without swelling, embrittlement, or material degradation during prolonged use.

  
  

• High-Temperature Equipment - For high-temperature equipment, the fluid’s flash point above 300°C and resistance to thermal oxidation allow reliable operation under sustained heat exposure. Viscosity stability ensures that damping performance remains predictable even during prolonged high-temperature service conditions.
