Thermally conductive thermoplastics for heat sinks and thermal management dissipate the same amount of heat as aluminum but are up to 50% lighter.
They also have no antenna effect (no amplification of electromagnetic or radio-frequency interference and no magnetic coupling).
E-Series grades are electrically conductive and provide inherent EMI/ RFI absorption. D-Series grades are electrically insulative and produce no signal interference and or magnetic coupling. They are available as injection-molding compounds, offthe- shelf parts, or as custom injection molded parts.
The polymer specs include thermal conductivity of 20 W/mK, thermal diffusivity of 0.1 cm2/sec, and density of 1.7 gm/cm3.
