ELBALUBES 2507 is a silicone based, metal oxide filled compound that is an effective transporter of thermal energy.  Effectiveness results from the ability to fill the interstitial spaces that exist between two coupled surfaces.  Since air is a poor conductor of heat, by essentially filling the voids with a pliable, thermally stable compound, thermal energy is more efficiently conveyed from the heat source to the sink.  Suggested Temperature Range: -40 to 200°C
