Keratherm Softtherm®: 86/300 and 86/320

This group of Softtherm® films has a very good thermal behavior. The films are characterized by low thermal resistance and best heat dissipation, as well as good dielectric strength. Good compressibility and low shore hardness ensure reliable and simple processability.

Possible Thickness:
     86/300: 0.5mm - 5.0mm
     86/320: 1.0mm - 5.0mm
