Description

The Kerafol Softtherm 86/525 is a versatile thermal interface material that offers exceptional thermal conductivity and compression performance. With a thermal conductivity of 5.5 W/mK, it is designed to efficiently transfer heat in high-demand applications such as computing and automotive systems. Its excellent compressibility allows it to fill in gaps and uneven surfaces, ensuring a reliable thermal connection between components. Additionally, the Softtherm 86/525 maintains good dielectric behavior, making it suitable for use in electrically sensitive applications. It is important to note that when applying maximum pressure, the material should not be compressed beyond 30% of its original thickness to prevent any potential leakage. This balance of high thermal conductivity and compressibility makes the Kerafol Softtherm 86/525 an ideal solution for managing thermal challenges in various applications.
