ShinEtsu KF-96H-300000CS - super high viscosity silicone lubricating oil for damping grease & as main grease raw material

Shin-Etsu KF-96H-300000cs is an ultra-pure dimethyl silicone fluid specifically engineered for high-viscosity instrument damping and heavy-duty mechanical stability. This 300,000 cSt fluid serves as a superior viscous silicone barrier oil, ensuring smooth operation in the most demanding precision environments.
PRODUCTS DESCRIPTION

KF-96H-300000cs is a non-reactive, clear, and odorless polydimethylsiloxane (PDMS) fluid designed for applications that require extreme resistance to flow and motion. As a leading solution for high-viscosity instrument damping, it excels at absorbing kinetic energy and eliminating unwanted mechanical vibrations in sensitive electronics and industrial machinery. Its high molecular weight makes it a reliable precision motion control fluid, maintaining consistent viscosity even under fluctuating thermal conditions. Additionally, its chemical inertness allows it to function as a specialized 300000 cst release agent for complex molding processes and a long-lasting viscous silicone barrier oil for moisture protection and lubrication.

Key features

  • Superior High-Viscosity Instrument Damping - Provides exceptional vibration suppression and shock absorption for gauges, meters, and delicate internal components.

  • Precision Motion Control Fluid - Delivers a smooth, consistent resistance that is essential for the steady operation of rotary dampers and dashpots.

  • High-Tack Viscous Silicone Barrier Oil - Creates a thick, non-migratory protective film that guards against moisture and chemical contaminants.

  • Industrial Grade 300000 cSt Release Agent - Facilitates clean and easy separation for heavy-duty plastic and rubber molding applications.

  • Excellent Thermal Stability - Resists oxidation and viscosity breakdown, ensuring the fluid performs reliably across a wide 2026 operational temperature range.



Application
  • Measurement Instrumentation - Specifically utilized for high-viscosity instrument damping in pressure gauges, aerospace dials, and high-precision weighing scales.

  • Mechanical Dampers - Functions as a primary precision motion control fluid in camera equipment, soft-close hinges, and automotive interior components.

  • Molding & Manufacturing - Applied as a specialized 300000 cst release agent where lower viscosity oils would fail to provide a sufficient barrier.

  • Protection & Sealing - Acts as a heavy-duty viscous silicone barrier oil for outdoor electrical connectors and mechanical gaskets exposed to harsh environments.

  • Seismic and Scientific Research - Used in specialized laboratory sensors and earthquake damping systems to absorb kinetic energy and stabilize readings.
