Thermally conductive sealant is a category of Thermal Interface Materials (TIM) that provides a combination of low thermal resistance and high bond strength. Thermal conductive sealant can be used in almost any application that requires resistance to extreme temperatures and it can withstand temperatures as low as 4K and as high as 600°F.
TIMs are designed to conform to surface irregularities, eliminate air gaps, and improve heat flow; and include grease, compounds, gels, pads, phase change materials (PCMs), metallic solders, and tapes. To maximize heat dissipation, choosing the right thermal interface material (TIM) is essential. The greater the temperature difference, the faster the heat flows to the colder area. Using this process, heat energy is passed through a solid, liquid or gas from molecule to molecule in a material. In order for the heat to be conducted, there should be physical contact between particles and some temperature difference.
The properties which make them thermal conductive are temperature resistance, thermal cycling resistance, viscosity, flexibility, cure times and other curious properties. It is the well designed thermal management system which involves efficient heat-dissipating components such as heatsinks, air or liquid cooling pipes and fans. Thus, Thermal conductive sealant helps in measuring the speed of heat flow passed from particle to particle. The rate of heat flow through a specific material will be influenced by the difference of temperature and by its thermal conductivity.
Dry stagnant gas is one of the best insulating materials. The higher is the number of cells which maintain the gas stagnant, the smaller is their size and their thermal conductivity is lower of such insulating materials. This measurement of high and low helps in deciding which insulation material you should choose.
