OPUTE 5W/mK Industrial Thermal Grease 30g Jar for Heat Sinks & Electronics
TG-50 Thermal Grease
OPUTE TG-50 is a silicone thermal grease designed for efficient heat transfer across thin thermal interfaces in computers and other high-power electronic applications. With a measured thermal conductivity of 4.8 W/m·K and a thermal resistance of 0.05 °C·cm²/W, TG-50 helps fill small gaps between heat-generating components and heat sinks. It offers electrical insulation, water resistance, low oil separation and non-corrosive properties for electronic thermal management applications.
