Phase Change Materials

What are Phase Change Materials?

Phase change thermal interface materials (TIMs) improve heat transfer between hot components and heat sinks. This allows the components to run at lower temperatures, which can increase their speed and lifespan. They are used in a wide range of demanding applications across many industries, including consumer electronics, telecom/datacom, automotive electronics, industrial electronics, medical, and military/aerospace.

How do Phase Change Materials Work?

The first phase change materials (PCMs) melted to a liquid state at temperatures between 50°C and 60°C. Today, most PCMs do not melt but soften at operating temperatures in the 50°C to 70°C range. This provides the same advantages of wetting and minimum bond line and offers better long-term reliability. PCMs are generally used in constant-pressure applications.

Characteristics and Functions:

• Thermal conductivity range: 1 – 8 W/mK
• Thickness range: 0.125mm to 0.5mm
• Compliancy: UL 94V0, RoHs, REACH
• Easy to use; peel and stick format with top tabbed liners or automatable placement
