Description

The Kerafol Keratherm 86/17 is a high-performance silicone elastomer film designed for efficient thermal management. With a thermal conductivity of 1.8 W/mK, it effectively dissipates heat, making it ideal for demanding applications. The film also boasts excellent electrical properties, including a dielectric breakdown voltage of 6.0 kV and a volume resistivity of (2.5 times 10^{11}) Ωm. Its mechanical stability and perforation strength are enhanced by optional fiberglass reinforcement, ensuring durability. Operating within a wide temperature range from -60°C to +250°C, the Keratherm 86/37 is versatile and reliable. Additionally, its UL-94 V-0 flame rating underscores its safety in various applications, such as automotive, telecommunications, and power electronics.
