Product Description
SILISIL Silicone Oil 20 cSt is PDMS for capacitor impregnation, dielectric insulation, and electronic applications.
SILISIL Silicone Oils are high-purity linear polydimethylsiloxane fluids (PDMS) with 100% purity. The viscosity of 20 cSt defines the application spectrum — from lubrication to release agents and hydraulic functions to specialized care and industrial applications.
20 cSt is the established viscosity for capacitor impregnation and transformer oil replenishment — good spreadability combined with high dielectric strength and low dissipation factor.

Frequently Asked Questions about SILISIL Silicone Oil 20 cSt
Practical application and design questions — answered by SILITECH.
SILISIL Silicone Oil 20 cSt: PDMS for capacitor impregnation, dielectric insulation, and electronic applications. Main applications include capacitor impregnation, transformer auxiliary oil, and electronic potting.
PDMS (polydimethylsiloxane) is a linear silicone fluid that combines high thermal stability, low surface tension, very good dielectric properties, and broad temperature resistance. The viscosity (measured in centistokes, cSt) determines the field of application — low viscosities are suitable for volatile applications and lubrication, high viscosities for damping and conditioners.
SILISIL Silicone Oils are soluble in aromatic, aliphatic, and chlorinated solvents (e.g., toluene, xylene, hexane, diesel). They are not miscible with water and alcohols. For anti-foam applications, high-viscosity PDMS is diluted in hydrocarbon solvents and introduced using a dosing pump.
Store in the unopened original container at room temperature (ideally below 60 °C). Avoid eye contact. SILISIL Silicone Oils are generally non-toxic, odorless, and tasteless — nevertheless, consult the Safety Data Sheet (SDS), which is available in the "Documents" tab.
Viscosity determines the application. 20 cSt is optimal for: capacitor impregnation and similar application profiles. For other application characteristics, you will find related viscosities in the comparison table above — if uncertain, we are happy to advise you on your specific application.
