Beating the heat with new thermally conductive polycarbonates

Last year, we gave readers a sneak peek into new thermally conductive (TC) polycarbonate grades from Covestro. Now, we are excited to announce the official launch of these new materials as we expand our Makrolon® TC polycarbonate portfolio, which provides passive thermal management in LED lamps and luminaires, and other market applications.

These new thermally conductive grades, which include a grade that is also electrically insulating, allow lighting designers and manufacturers to replace the metal in heat sink applications, integrate more functions and reduce the number of components.

The new Makrolon® TC polycarbonate grades are lightweight, offer design freedom and are easy to process. These properties make Makrolon® TC polycarbonate an alternative choice when compared to aluminum – a material traditionally used in heat sinks – and other thermally conductive plastics. Additional advantages of Makrolon® TC polycarbonate over these materials include:

  • High-dimensional stability over a wide service temperature range
  • Optimized design by reducing components through consolidation
  • Reduced manufacturing complexity utilizing in-mold assembly of electronics
  • The ability to be combined with other polycarbonates in multi-component processing
New Makrolon® TC polycarbonate grades provide improved processing and options for injection molding and profile extrusion.

With the new Makrolon® TC grades, Covestro is providing lighting manufacturers and designers with a material solution for thermal management that offers design freedom, and is lighter and easier to process.

From May 8-10 in Chicago, LIGHTFAIR International attendees can visit the Covestro booth (#3781) to learn more about these thermally conductive grades for LED lighting and other applications.
