phase change thermal film for device cooling - Xophase 45

XoPhase 45 is a free standing 45C phase change thermal film offering high performance heat transfer and device reliability.   XoPhase 45's unique formulation not only allows for surface conformability during initial phase change but also offers a soft interface pad solution within a film format that provides a reduction in the interface bond line (thickness) leading to high performance thermal transfer within large or small device footprints.



XoPhase 45 is manufactured standard in 4 mil, 8 mil and 12 mil free standing film thicknesses.  The ability to manufacture XoPhase 45 in a variety of film thicknesses as well as in a one sided substrate coating option allows us to meet a wide range of device applications across various markets.
