DIAPHASE 60 PHASE CHANGE MATERIAL (KAPTON MT)
Diaphase 60 Phase Change Thermal Interface Material
Diaphase 60 is high performance dielectric phase-change material which utilizes Kapton® MT polyimide film to act as a thermally conductive carrier in order to deliver a uniform thickness coating of Diaphase 60 phase-change thermal compound on both sides. Through the development of this unique formulation, Diaphase 60 offers efficient thermal transfer by phase-changing during normal device operating temperatures while maintaining a uniform bond line thus driving out the air and adjusting for any surface imperfections or flatness conditions that may exist across the interface.
Being able to manufacture Diaphase 60 in multiple compound thicknesses as well as Kapton MT thicknesses allows us to meet a wide range of electronic cooling applications ranging from transistors, diodes or any type of heat generating non-isolated power device requiring efficient and reliable thermal transfer into a heat sink/case sink or heat dissipating structure.
