M45 PHASE CHANGE THERMAL INTERFACE FILM
M45 Phase Change Thermal Interface Film
M45 is a free standing 45C phase change thermal film designed to provide high performance heat transfer for a variety of power module packages, LED assemblies, CPU/Sink or any demanding electronics cooling application where efficient and reliable heat transfer is required.
Available standard as either a 6 mil (0.15mm), 8 mil (0.20mm) or 12 mil (0.30mm) thick free standing phase change film in either sheet or die cut format.
Upon initial phase change, M45 begins its controlled flow from its original pre-formed die cut size adjusting for surface irregularities and flatness conditions leading to improved thermal performance. This also includes a reduction of the bond line thickness as mounting pressures are increased.

Release Liner | Thermal Pad Transfer System
When designing our M45 Phase Change Film, the thermal performance was not the only target. An additional key advantage in using M45 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.
M45 is delivered with a top and bottom clear release liner. The top liner is removed first to expose the top of the M45 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.
