PCF series is a high-performance phase change thermally conductive material designed for demanding thermal applications, such as high-efficiency processors, thermal modules, and heat sinks. The PCF material offers extremely low thermal resistance between components and heat sinks, ensuring optimal heat transfer.
The material melts at a temperature range of 50-57°C, flowing without overflowing. As it melts, it effectively squeezes out air from the gap, thoroughly wets the contact surfaces, and forms a very low thermal resistance layer.
Naturally tacky, the PCF material requires no adhesive layer, making it ready for immediate use. It can also be easily die-cut into various shapes to meet specific application needs. Available in both sheet and roll formats, it offers flexibility and convenience for a wide range of thermal management solutions.
Our Phase Change Material provides ultra-low thermal resistance by transitioning to a liquid state at operating temperatures. To ensure the highest accuracy in our performance ratings, we validate all thermal impedance data using the ASTM D5470 standard. This rigorous testing ensures our materials provide the consistent, high-efficiency cooling required for the most demanding high-power computing and automotive applications.
