XBH Series

Phase Change Interface Material

XBH series phase change thermal pad is a solid sheet at room temperature. It is a thermal conductive filling material that has begun to soften at 45-55℃. The thermal conductive phase change material has the special characteristics of softening micro-flow after absorbing heat and recovering the solid shape after cooling. It has excellent wettability and compressibility. It can be cut into various sizes according to customer requirements and attached between the heat sink and the power-consuming electronic device. The filling heat comes from the gap between the heat sinks, which minimizes the thermal resistance.

Product Features

High thermal conductivity, low impedance
Tightly fit irregular device surfaces
Excellent compressibility, excellent wettability, high reliability
Low volatility --- less than 1%

Applications:

Communication equipment
Automotive electronic equipment
Security equipment
