XOPHASE 45 PHASE CHANGE THERMAL INTERFACE FILM
XoPhase45 Phase Change Thermal Interface Film
XoPhase 45 is a free standing 45C phase change thermal film designed to provide reliable and efficient heat transfer for a variety of electronic device applications including LED, thermoelectric modules or microprocessor/sink assembly. Available standard as either a 5 mil, 8 mil or 12 mil thick free standing phase change film, XoPhase 45 is ideal for ultra-flat surfaces with a flatness condition of ~ 0.002” (0.051mm) or less within lower pressure applications.
Upon initial phase change, XoPhase 45 begins its controlled flow from its original pre-formed die cut size adjusting for surface irregularities and flatness conditions leading to improved thermal performance.

Release Liner | Thermal Pad Transfer System
When designing our X45 (XoPhase) Phase Change Film, the thermal performance was not the only target. An additional key advantage in using X45 is the offering of the TIMTEL Die Cut Thermal Pad Transfer System.
The purpose of this die cut design was to avoid common installation issues typically experienced by similar phase change thermal pads on the market place today such as not releasing properly from the liner and pad tearing.
X45 is delivered with a top and bottom clear release liner. The top liner is removed first to expose the top of the X45 film. Once the top liner is removed, the pad is applied to the module or application surface, slight even pressure is then applied, and the final liner with extended tab is removed.
