Softtherm 86/500, 86/600 - Keratherm

This group of Softtherm films exhibits the best thermal behavior of our available gap-fillers. The group is characterized by its low thermal resistance and best heat dissipation, and good dielectric strength at the same time. The good compressibility and low Shore hardness ensure reliable and simple processability.

Possible Thickness:
86/500: 0.5mm – 2.0mm
86/600: 0.5mm – 1.5mm
