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 5 mil, 8 mil or 12 mil 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 M45 to achieve excellent thermal transfer results, 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.
