Introducing
CHO-THERM® HV Series
Thermally Conductive Pads with Enhanced Electrical Insulation
Parker Chomerics CHO-THERM HV Series is a family of thermally conductive and electrically insulating pads, with thermal conductivities ranging from 1.1 to 3.3 W/m-K, providing breakdown voltages of up to 20 kV under DC load. 

Engineered to provide effective heat transfer from heat generating components (CPUs, GPUs, high power busbars, etc.) to heat dissipating components (cold plates, heat sinks, cooling pipes, vapor chambers, etc.) within electronic devices and systems. 

The CHO-THERM HV series offers the ideal combination of high thermal and low outgassing performance while requiring ultra low compression forces during installation and use. With Shore 00 hardnesses ranging from 30 to 35, the HV Series allows for exceptional conformability between uneven mating surfaces with rough surface textures in order to eliminate air gaps.

For enhanced electrical insulation and electrical breakdown resistance, the HV Series features high-performance dielectric layers to provide electrial isolation between high power components utilized in the most demanding automotive and industrial systems.

Available in custom diecut geometries for complex surface areas or large format sheets for high volume conversion, the CHO-THERM HV Series can be provided in the configuration most suited to the demanded assembly process.
