*Phase‐change material exhibits 1014 ohm‐cm volume resistivity. Metal foil is electrically conductive.
**The phase‐change material is electrically non‐conductive. However, as it contains dispersed solder for
enhanced thermal properties, it can exhibit through‐conductivity at thinner bond line thickness
(approximately <2mils). It should not be used as an electrical insulator.
*** The lower phase‐transition temperature is for the polymer. The higher value is for the low melting alloy filler.
