Phase Change Materials

Aavid offers unique phase-change thermal interface materials that while absorbing heat change from a solid to a liquid form. During this transition, the material maintains a consistent temperature while high amounts of heat are absorbed. Once in a liquid state, the material is capable of removing any residual air pockets and the heat transfer is substantially increased. During cool down, excess heat is released, helping to keep a steady temperature.

Ultrastick - Phase Change Interface Material

ultrastickAavid Ultrastick is a unique phase-change 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 volumetric expansion that fills an remaining gaps between mating surface. Ultrastick comes in a convenient applicator bar which allows for neat, fast application to both heat sink and heat source. Ultrastick is cost-effective and is applied in a thin film-like deposit that provides excellent heat transfer and low thermal resistance.
