Technical Data December 2013 3MTM Thermally Conductive Silicone Interface Pads 5519 and 5519S Product Description 3MTM Thermally Conductive Silicone Interface Pads 5519 and 5519S are designed to provide a preferential heat transfer path between heat generating components and heat sinks, heat spreaders or other cooling devices. These products consist of a highly conformable slightly tacky silicone elastomer sheet filled with thermally conductive ceramic particles which provide special features listed as follows. *Very high thermal conductivity and good electrical insulation properties. *Good softness and conformability even to non-flat surfaces. *"S" version incorporates a thin polymeric film carrier for improved handling. *Slight tack allows pre-assembly. Good wettability for better thermal conductivity.

Dielectric Constant ASTM D150 19.5 (1-100 kHz) Notes: 1) Shore OO Test Method based on a 6mm thick sample. Results will vary for different thickness samples. 2) Thermal conductivity can vary with test method and/or equipment used for testing at different test sites. Thermal K based on testing of the 5519. Effective Thermal K and Thermal Resistance will be somewhat reduced with the addition of the polymeric film of the 5519S constructions.
