CoolPoly D-series - Thermally Conductive Dielectric Plastics

CoolPoly® D-series
CoolPoly® D-series Thermally Conductive Plastics exhibit electrical isolation in addition to their thermal conductivity. Common plastics are also electrical insulators. The electrical insulation property of the material is measured as electrical resistivity and is typically in the range 1012 to 1016 ohm-cm for both conventional plastics and D-Series plastics. The thermal conductivity of CoolPoly D-Series plastics enhances their electrical isolation and dielectric properties beyond the range of conventional plastics.

Conventional plastics are considered thermal insulators. The thermal conductivity of CoolPoly D-series thermally conductive plastics range from 1.0 W/mK to 10 W/mK. This exceptional level of thermal conductivity in a plastic is 5 to 100 times the value of conventional plastics. The optimal level of thermal conductivity for any application depends on the power input, size of the part and the convection conditions. Cool Polymers technical service staff can help engineers determine the appropriate materials for their application and heat transfer requirements.


CoolPoly D-series thermally conductive plastics surpass the isolation and dielectric properties of conventional plastics. The heat transfer inherent in CoolPoly D-series plastics reduces the localized overheating due to electrical charging and retards the formation of carbon tracking.

CoolPoly D-series plastics are characterized for their electrical isolation and dielectric characteristics in addition to their general thermal, mechanical and physical properties. Properties measured include volume and surface resistivity, dielectric constant and dissipation factor, dielectric strength, comparative tracking index, arc resistance, hot wire ignition, high voltage arc tracking rate, and high voltage arc resistance to ignition.

Common uses for CoolPoly D-series plastics include encapsulation of wire wound and electromechanical devices, resistors, switches, relays, sensors, and connectors.

CoolPoly D-series plastics combine the thermal conductivity and electrical isolations in standard pellet form suitable for thermoplastic injection molding and other processes (e.g. extrusion). CoolPoly D-series plastics are available in bag, drum, and Gaylord packaging.
