This group of Softtherm films has the best 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.
Optional available with adhesive coating!
The following film thicknesses
are available:
86/300: 0.5 - 5.0 mm
86/500: 0.5 - 2.0 mm
86/600: 0.5 mm; 1.0 mm; 1.5 mm
Applications:
RD-RAM memory modules
Heat pipe thermal solutions
Automotive engine
Control units
Plasma supply console
