The Poisson's ratio of thermal grease is a key parameter that directly affects its thermal and mechanical performance.Poisson's ratio is a critical parameter in material mechanics, defined as the ratio of transverse strain to axial strain when a material is stretched or compressed.

When the CPU temperature rises, sensors on the motherboard detect this change and increase the cooling fan speed to improve cooling. Therefore, when dry thermal grease leads to higher CPU temperatures, the cooling fan will respond by speeding up in an attempt to lower the temperature.

As crucial thermal materials, alumina (Al₂O₃) and magnesia (MgO) each have unique advantages and suitable application fields. Magnesia excels in high thermal conductivity and high-temperature applications, while alumina is widely used due to its good overall performance and cost-effectiveness. The choice between these materials should be based on specific application requirements, cost considerations, and performance needs.

Though accidental ingestion of thermal grease is uncommon, it can cause various health issues if it occurs. Understanding its components and potential hazards, along with taking timely and appropriate response measures, can effectively reduce its impact on health.

Silicone thermal grease enhances thermal conductivity and electrical insulation in electronics, ensuring efficient heat dissipation and optimal performance across various industries.

Thermal silicone pads are suitable for use in laptop chips, motherboard chips, power supply MOS tubes, and other components that do not require extremely rigorous heat dissipation. They serve as a filler between chips and heat sinks. Their advantages include consistent thermal conductivity, eliminating uneven application issues common with thermal paste. Moreover, they can be tailored to size, simplifying installation. Their self-adhesive properties allow for repeated applications in laptop's confined spaces, without adversely affecting performance.

The thermal expansion coefficient (CTE) of thermal conductive silicone pads measures how much the material expands or contracts with temperature change, crucial for ensuring electronic devices' stability and longevity. It's influenced by composition, filler properties, manufacturing processes, and impacts thermal stability, mechanical performance, and reliability. Optimizing CTE is vital for effective heat management in electronics.

Thermal pads, vital for heat management in electronics, act as TIMs, enhancing heat transfer between components and heat sinks. Composed of polymer matrices filled with thermally conductive materials, they fill air gaps, reducing contact resistance and facilitating heat flow via conduction.

Thermal pads and thermal grease are key heat management materials. Thermal pads offer ease of use, durability, and electrical insulation, suitable for long-term applications. Thermal grease provides superior thermal conductivity for high-performance scenarios but requires precise application and periodic maintenance.

For LED heat dissipation applications, thermal silicone pads, with their superior thermal performance, ease of installation, environmental safety, long-term reliability, and cost-effectiveness, are gradually becoming the ideal choice over thermal grease.

Thermal grease's thermal conductivity and viscosity are key performance indicators, influenced by composition and microstructure, requiring a balance for optimal application.
