An added stabilizer delays oxidation, extending service life during sustained high-temperature operation. Labs choose C20S for hot oil-bath work that ordinary fluids cannot endure for long.\u003c\/p\u003e\n\u003cp\u003eSilicone chemistry stays inert against common metals and holds very low electrical conductivity. Operators should avoid silicone tubing, which silicone fluids degrade. Above 150 °C the fluid forms vapor below the flash point; ensure adequate ventilation at elevated temperatures. Regular fluid checks near +220 °C keep performance consistent.\u003c\/p\u003e\n\u003ch2\u003eSpecifications\u003c\/h2\u003e\n\u003ctable\u003e\n  \u003ctr\u003e\n\u003cth\u003eProduct Type\u003c\/th\u003e\n\u003ctd\u003eHeat Transfer Fluid\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003cth\u003eFluid Type\u003c\/th\u003e\n\u003ctd\u003eSilicone, stabilized\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003cth\u003eViscosity\u003c\/th\u003e\n\u003ctd\u003e20 cSt\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003cth\u003eColor\u003c\/th\u003e\n\u003ctd\u003eLight brown\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003cth\u003eWorking Temperature Range\u003c\/th\u003e\n\u003ctd\u003e0 to +220 °C\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003cth\u003eCompatible Equipment\u003c\/th\u003e\n\u003ctd\u003eOpen-bath heating circulators\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003cth\u003eAdditive\u003c\/th\u003e\n\u003ctd\u003eOxidation stabilizer\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003cth\u003ePackaging\u003c\/th\u003e\n\u003ctd\u003ePoly Pail\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003cth\u003eAvailable Sizes\u003c\/th\u003e\n\u003ctd\u003e5 L, 10 L\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003cth\u003eBrand\u003c\/th\u003e\n\u003ctd\u003eJulabo\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003cth\u003eShips From\u003c\/th\u003e\n\u003ctd\u003eUSA\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\u003ch2\u003eAvailable Sizes and Configurations\u003c\/h2\u003e\n\u003ctable\u003e\n  \u003ctr\u003e\n\u003cth\u003eSKU\u003c\/th\u003e\n\u003cth\u003eDescription\u003c\/th\u003e\n\u003cth\u003ePack\u003c\/th\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd\u003e64502\u003c\/td\u003e\n\u003ctd\u003eThermal C20S Stabilized Silicone Fluid, 5 L\u003c\/td\u003e\n\u003ctd\u003e5 L Poly Pail\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd\u003e64502\u003c\/td\u003e\n\u003ctd\u003eThermal C20S Stabilized Silicone Fluid, 10 L\u003c\/td\u003e\n\u003ctd\u003e10 L Poly Pail\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\u003ch2\u003eLaboratory Applications\u003c\/h2\u003e\n\u003cp\u003eThermal C20S serves high-temperature heating baths in chemistry, materials, and QC labs operating to +220 °C.
