TG3000I Thermal Silicone Grease is the best thermal grease of our entire product line. It offers excellent thermal properties (3.0 TC and 0.003 TI) while also exhibiting excellent electrical properties. TG3000I has a maximum particle size of 7um and can reach a bond line thickness of 7 micron @35psi, 50oC. Its low viscosity and excellent thixotropy make it fit for large–scale production with dispensing, screen printing and stencil printing. Even though TC is seemingly average, the combination of Thermal impedance and minuscule bond line thickness along with its great electrical properties, make it the most advanced thermal grease in the market.
TG3000I is used for applications with highly advanced power density requirements. It is designed to minimize thermal resistance at interfaces, and maintain excellent performance through reliability testing. It provides superior thermal performance with ease of use across a multitude of applications. Its operating temperature range is -40oC to 150oC like the entire Thermal grease product range.
After conducting a thermally degrading test you might realise that these greases are highly filled(~93.5% residual mass). Can this be a cause for concern when it comes to fretting and friction? The short answer is no.
The long answer is that Zinc oxide and aluminum oxide are common fillers in greases and other TIMs. These materials are also used in our phase change TIMs and there has rarely been any issues with fretting (friction) during dispensing or other applications. Fretting is only a concern with boron nitride as filler. Friction related impact is also minimal on low viscosity greases. So you are safe.
