Softtherm 86/450 - Keratherm

This soft hybrid heat-conducting film has been developed for pressure-sensitive uses in the middle and upper performance ranges. Besides very good thermal and dielectric characteristics the film is also highly suitable for automatic placement.

This carrier-free film is available in thicknesses from 0.5mm to 3.0mm. Special attention was paid to the film’s processability and cost optimization.

Possible Thickness: 0.5mm – 3.0mm
