DIAPHASE 60A ADHESIVE BACKED PHASE CHANGE
Diaphase 60A Tack Backed Phase Change Thermal Interface
Building upon the thermal performance and dielectric strength of our standard Diaphase product line, Diaphase 60A is built with a 0.5 mil (0.013mm) repositionable pressure sensitive adhesive backing to allow for a pre-applied pad function for installation.
DiaPhase 60A still utilizes on one side the benefits of the 60C phase change thermal compound coating as well as the handling and dielectric strength capability of the Kapton MT polyimide substrate.
DiaPhase 60A is delivered with an easy to remove clear release liner (adhesive side) and can be further processed through die cutting with a liner tab extension for the die cut part (or multiple per master sheet).
