The MPC25 is a 130 x 310 x 0.25mm Thermal Phase Change Wax, bridging the gap between a thermal paste and solid filler pad a phase change wax-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. This MPC series 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.
