3.5 W/m·K Thermal Conductive Grease

Inquiry

The ALOS-SILI-431 thermal conductive grease is crafted using high-purity thermal conductive filler combined with a modified silicone matrix through a precise blending process. This results in a stable thermal conductivity of 3.5W/m·K, meeting the stringent thermal management material standards of the electronics industry. When applied, this product effectively infiltrates any microscopic irregularities between the surface of the heat-generating components and the heat sink, ensuring a low thermal contact resistance. This facilitates efficient heat transfer from the components to the heat sink or housing, achieving superior thermal performance under operational conditions. As a reliable thermal interface material, it is characterized by minimal weight loss and has undergone rigorous testing to ensure long-term and stable reliability.

Properties

Stable thermal performance. With a consistent thermal conductivity of 3.5W/m·K, it ensures high and stable heat transfer efficiency. This allows for rapid temperature equilibrium across components, preventing performance degradation due to localized overheating.
Exceptional temperature adaptability. This grease can operate reliably over a wide temperature range from -50°C to 200°C. Its consistency remains largely unaffected by temperature fluctuations, ensuring no melting at high temperatures and no solidifying at low temperatures.
Superior chemical stability. It is non-corrosive to materials like iron, steel, aluminum, and various synthetics, guaranteeing long-term reliability during extended use.
Easy application. Featuring excellent thixotropic properties, it has a smooth and fine texture that can be applied using tools like spatulas or dispensers. The coating process is straightforward, yielding a uniform layer without clumping, while allowing for easy control of coating thickness.
Low oil bleeding. Prolonged use shows no significant oil bleeding, which helps maintain cleanliness around components and prevents contamination of adjacent parts.
Environmental safety. Free from hazardous heavy metals such as lead and mercury, as well as volatile organic compounds, it complies with RoHS and other environmental standards, ensuring a safe and pollution-free usage experience.

Directions for Use

Surface preparation: Begin by thoroughly cleaning the surface that needs to be coated. Use suitable cleaning techniques, such as wiping or washing, to eliminate all impurities. It's imperative that the surface is completely free from dust, grease, and any other contaminants to ensure optimal adhesion and performance of the thermal grease.
Application of thermal grease: Utilize a brush or scraper to evenly spread a layer of thermal conductive silicone grease over the target surface. For maximum thermal transfer efficiency, ensure the entire area is covered without leaving any gaps. More thermal grease is not necessarily better; a thin layer, ensuring complete filling of all gaps, is preferable.
