Key Performance Advantages
As a low-viscosity thermal conductive medium, this ethyl silicone oil delivers exceptional heat transfer efficiency while maintaining operational safety due to its high flash point. The material demonstrates outstanding dielectric properties, suitable for thermal management in high-power radio frequency equipment and electronic systems.

The silicone oil exhibits remarkable chemical stability, remaining inert when exposed to most strong acids and alkalis, though it is not recommended for use with concentrated sulfuric acid and hydrofluoric acid. Its wide operating temperature range from below -85°C to above 180°C ensures consistent performance in both extreme cold and high-temperature applications.

Primary Applications

• Thermal interface material for electronic components and power devices

• Cooling medium for high-frequency communication equipment

• Heat transfer fluid in precision instruments and laboratory equipment

• Dielectric coolant for electrical systems requiring insulation

• Lubricant for low-temperature mechanical applications
