AAVID ULTRASTICK™
PHASE-CHANGE
THERMAL INTERFACE CO MPO UND
TH E R M A L P R O D U C TS, I N C.
Aavid’s Ultrastick is a unique phase-change thermal
interface material that surpasses grease in thermal
performance and long-term stability.This solid,
silicone-free, paraffin-based thermal compound
changes phase at 60°C, with a concurrent volu-
metric expansion that fills gaps between the
mating surfaces. Ultrastick comes in a convenient
applicator bar, allowing for neat, fast application
to both heat sink and component surfaces.
One cost-effective application leaves a thin, film-
like deposit, providing excellent heat transfer and
low interface thermal resistance.
