SILISIL Silicone Oil 5000 cSt is a high-viscosity PDMS — the standard choice for demanding lubrication, damping and release film applications.
SILISIL Silicone Oils are high-purity linear polydimethylsiloxane (PDMS) liquids with a purity of 100%. Their viscosity of 5,000 cSt defines their range of applications — from lubrication and release agents to hydraulic functions and specialized care and industrial applications.
5,000 cSt is the most widely used high-viscosity PDMS class — standard for industrial steamers, premium release agents, and specialty lubricants. It offers higher film stability than 1,000 cSt while still being processable.

Frequently asked questions about SILISIL Silicone Oil 5000 cSt
Practical application and design questions — answered by SILITECH.
SILISIL Silicone Oil 5000 cSt: High-viscosity PDMS — the standard choice for demanding lubrication, damping, and release films. Main applications include industrial dampers, premium injection molding release agents, and heavy-duty lubrication.
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.
The viscosity determines the application. 5,000 cSt is optimal for industrial dampers and similar application profiles.
