Plastic for LED Heat Sinks Could Reduce Lighting Costs

Researchers at Bayer MaterialScience have developed thermally conductive polycarbonate to replace aluminum in heat sinks, thereby reducing assembly steps in the manufacture of LEDs, says the company. Thermally conductive polycarbonate can reduce cost per unit in applications such as multi-faceted reflector or parabolic aluminized reflector lamp configurations.

Bayer MaterialScience says its thermally conductive Makrolon TC8030 polycarbonate can not only successfully replace aluminum as a heat sink material and offer a solid value proposition in reducing assembly cost, but it can also permit shapes and features that are not possible with aluminum.
