What is 10,000 cSt silicone oil used for?
A damping-and-durable-lubrication grade: vibration and shock control in dampers and instruments, plus durable, heat-resistant lubrication of polymer parts. High viscosity with strong damping action, high compressibility and a low viscosity-temperature coefficient means performance changes little with temperature.
Dimethicone- ▸ Damping media and hydraulic stabilizers — insulating and damping in one fluid
- ▸ Durable heat- and shear-resistant lubrication for treadmill belts, O-rings, gaskets and rubber/plastic interfaces
- ▸ Electrical insulating / dielectric fluid
- ▸ Polish and protective-coating ingredient — gloss with a durable film
- ▸ Release agent and leather / textile auxiliary; personal-care conditioning (velvety skin feel)

Values shown are typical for the current commercial grade. A lot-specific Certificate of Analysis accompanies every shipment; the grade-specific SDS is available on request.
Mid- and high-viscosity polydimethylsiloxane fluids (>= 5 cSt) are reported as not meeting GHS hazard-classification criteria. The grade-specific SDS governs. A full SDS is supplied with every shipment and on request; hazard status is confirmed against the grade-specific SDS.
Cross-reference: comparable to XIAMETER PMX-200 Silicone Fluid 10,000 cSt (a Dow product): the same linear polydimethylsiloxane chemistry at the same nominal viscosity. RawSource is independent of Dow; confirm grade-critical specs against the RawSource TDS and lot CoA.
Silicone Oil 10,000 cSt is a damping-and-durable-lubrication grade. High viscosity with strong damping action, high compressibility and a low viscosity-temperature coefficient means vibration and shock control with little property change, while its high shear stability gives durable, heat-resistant lubrication of polymer parts.
Frequently Asked Questions
What is silicone oil 10000 cSt used for?
Silicone Oil 10,000 cSt is a high-viscosity PDMS (dimethicone) fluid used in damping, lubrication, release, and formulation applications that call for a thick, slow-flowing silicone with substantial film body. Match the viscosity grade to your specific application.
What does cSt mean in silicone oil?
cSt is centistokes, the unit of kinematic viscosity. For silicone oil (PDMS, CAS 9006-65-9) it indicates how thick the fluid is; 10,000 cSt is a high-viscosity grade, much thicker than the common 100-1,000 cSt fluids.
How does 10,000 cSt compare to lower silicone oil grades?
At 10,000 cSt the dimethicone fluid is markedly thicker and slower-flowing than 10, 100, or 1,000 cSt grades, giving heavier body and film. All share CAS 9006-65-9; the difference is polymer chain length, which sets the viscosity.
What is the CAS number for silicone oil 10000 cSt?
Silicone oil (dimethicone, PDMS) carries CAS 9006-65-9 with repeating-unit formula (C2H6OSi)n. The 10,000 cSt label is the viscosity grade, not a distinct CAS; all dimethicone grades share this number.
Can silicone oil 10000 cSt be supplied in bulk?
Yes. RawSource supplies 10,000 cSt silicone oil in drum, tote, and IBC quantities to manufacturers. Request a bulk quote with your target volume and packaging; CoA and SDS are available on request.
