UniPhase 4000-COB is a non silicon, high performance, phase changing thermal interface material, formulated to function as a superb alternative to messy and inconsistent thermal grease. Supplied as custom cut parts or in sheets, UniPhase 4000-COB will flow at a phase change temperature of 50°C and conform to the differing surface textures between a heatsink and LED COB or other device. In combination with device mounting pressure and phase change flow, UniPhase 4000-COB expels air voids at the interface helping to reduce thermal resistance.
