What is the Thermally Conductive Greases Fill-Grease 550?
Techinno Fill-Grease 550 is a high performance silicone grease based material with a thermal conductivity of 5.5W/m-K. The unique formula achieves excellent wettability and ultra-low bond line thickness, which allows Fill-Grease 550 fully fill the interface tolerances, minimize the interface thermal resistance. The product possesses good thixotropy and low viscosity for rapid dispensing or stencil screen printing applications.
Fill-Grease 550 has excellent long-term reliability, and is designed with no dry out and no pump out. These properties make it widely used in high-power thermal management components such as laptop CPUs, computer microprocessors, cloud computing systems, data processing and storage servers, data network and telecommunications infrastructure, gaming consoles, smart vehicle electronics, and AI-optimized GPUs.
