The Multidimensional Value and Application Prospects of Fluorosilicone Oil in the Electronics and Electrical Industry

Hits: 158 img

I. Material Properties: Redefining Industry Standards
Surface Tension Breakthrough
With a dynamic surface tension as low as 18-22 mN/m (compared to approximately 21-25 mN/m for standard silicone oil), it quickly spreads to form a nanoscale protective film, effectively penetrating micron-sized gaps between components. Tests on a PCB board showed that a fluorosilicone oil coating reduced solder joint oxidation by 72%.

Electrical Insulation Properties
Volume resistivity >1×10¹⁵Ω·cm (25°C), dielectric strength reaches 25 kV/mm. In 5G base station high-frequency circuit testing, it reduced signal loss by 34% compared to traditional materials.

Environmental Adaptability
Stable operation at -40°C to 250°C, passing a 3000-hour dual 85°C test (85°C/85% RH). Adoption in a new energy vehicle ECU module reduced the failure rate in humid environments by 89%.

II. Technology Evolution
Compound Modification Technology
A recently developed graphene-fluorosilicone oil hybrid material increases thermal conductivity to 5.6 W/(m·K) while maintaining insulation properties. It has been successfully tested in a military radar power module.

Intelligent Applications
Temperature-responsive fluorosilicone oil automatically forms a porous structure at 120°C to release stress, solving the thermal expansion problem of power devices. Tests by an IGBT manufacturer showed a zero module breakage rate.
