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.
