Thermal Gap Filling Materials

E specially designed ThermoFill materials by United Adhesives Inc. are for coupling thermal stress while dissipating heat. They form almost “stress-free” status at interface between electronic components and devices, which yield superior long lifetime in thermal cycles and operations. They have the following features:

-                High thermal conductivity & heat dissipating capacity

-                Soft and flexible for stress free gap filling

-                Flexible cure profile. Some are room temperature curable

-                Automated dispensable and printable

-                Tack after cure to provide necessary adhesion

-                All the ThermoFill materials are reworkable

They can be used in semiconductor, telecommunication, and automotive electronic industries. They are typically applied between high power devices and heat sinks, and any places where require to couple thermal stress while dissipating heat, or require thermally conductive vibration dampening
