Cermax is a broad range of machinable and fully dense ceramic materials providing high temperature insulation thermal shock resistance and high dielectric strength.
Heat exchangers do their job by transferring heat to achieve heating or cooling.
These conductivity values are averages due to the variance in thermal conductivity depending on the equipment used and the environment where the measurements were obtained.
Examples of conductors include copper aluminum platinum gold silver ionized water and trees.

Second the fr4 epoxy glass or phenolic based materials for moderate duty not run thru ovens and wave solder repeatedly.
Of course the graphite has good thermal conductivity.
A wide variety of non heat conductive materials options are available to you such as in stock items.
List of conductive and non conductive materials created date.
These electrons are able to move freely through the conductive material and allow electricity to flow.
The opposite of insulators are conductors.
Conductive materials are compounds that are comprised of atoms with free electrons.
Diamond is the leading thermally conductive material and has conductivity values measured 5x s higher.
Thermal conductivity is the term that describes how quickly a material absorbs heat from areas of high temperature and moves it toward areas of lower temperature.
