Staying cool in a hot market
Thermally conductive polycarbonate grade for heat sinks
The light emitting diode (LED) market for lighting products is heating up as consumers switch from incandescent bulbs to a more energy-efficient LED light source. Designers and manufacturers are looking for materials to help make the bulb transition a smooth one. When it comes to responding to evolving market trends, Covestro is light years ahead.
When a LED reaches a high temperature, its color attributes change, the lumen output decreases and its lifetime shortens. A heat sink is critical to the performance of a LED by helping to dissipate the heat. Aluminum has been a popular material to use in heat sinks, but it has disadvantages, including its weight and design limitations
Makrolon® TC8030 polycarbonate is the latest addition to the Covestro family of heat-resistant plastics developed specifically for LED applications. This thermally conductive grade is targeted for the of use LED heat sinks for replacement lamps or next-generation luminaires. Makrolon® TC8030 polycarbonate has an Underwriters Laboratories (UL) 94 flame class rating of V-0 at 2.0mm and a f1 listing.
Compared with aluminum, this grade of Makrolon® TC8030 polycarbonate conduct similar thermal performance while helping to reduce costs and enhance design freedom.
Moreover, this material can help save costs by eliminating assembly steps, improving production efficiency and reducing capital investments. Because it is injection molded, designers have the freedom to create non-traditional shapes, use in-mold decoration and optimize joining techniques.
With many popular consumer products experiencing overheating issues that affect product life, designers can look to thermally conductive plastics, such as Makrolon® TC8030 polycarbonate to help keep products cool as markets heat up.
The main properties of Makrolon® TC8030 polycarbonate are:
- Thermally conductive
- Corrosion resistant
- Low density
- Heat Resistant
