Thermal Phase Change
Bridging the gap between a Thermal Paste and Solid filler pad a phase change material is an ideal material. At room temperature it is a solid filler pad but when its transition temperature is reached it softens or melts and behaves more like a paste/grease. There are two types of materials, waxed based type and elastomer type. The wax based material has good wetting characteristics and low viscosity the material is ideal to fill any microscopic surface irregularities resulting in very low thermal resistance. It does not dry out, separate or settle. The elastomer type has good compressibility, and is available with single sided adhesive. It is also ideal where re-workability is required.
Due to the physical characteristics of phase change material it is easier to handle and process than paste/grease and yet still offer good thermal conductivity with low thermal resistance.
Can be supplied Die cut to customers specification.
