Covestro thermally conductive polycarbonate for LED heat sinks

Staying cool in a hot market

With many popular consumer products experiencing overheating issues that affect product life, designers must address the issue of dissipating heat in electronics. One focus area is lighting.

Heat Sink
Covestro developed Makrolon® TC8030 thermally conductive polycarbonate for use in LED heat sinks for replacement lamps or next-generation luminaires.

Task

The LED market is heating up as consumers switch from incandescent bulbs to more energy- efficient LEDs. 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.

Challenge

When an 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 an LED, helping to dissipate heat. Aluminum has been a popular material, but it has disadvantages, including its weight and appearance.

Solution

Makrolon® TC8030 thermally conductive polycarbonate from Covestro is targeted for use in LED heat sinks. This grade of Makrolon® polycarbonate offers similar thermal performance as aluminum but with added benefits. Covestro’s 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 processes and optimize joining techniques.

Makrolon® polycarbonate - the state of the art design all-rounder with phenomenal material properties

Makrolon® TC8030 polycarbonate has earned the Underwriters Laboratories 94 flame class rating of V-0 at 2.5 mm.

Since Makrolon® TC8030 polycarbonate is a thermally conductive grade, it acts as a channel for heat to pass through.

This material offers enhanced design freedom enabling lighting manufcturers and designers to create shapes and features not possible with alternative materials, such as aluminum.

Makrolon® TC8030 polycarbonate is lightweight which in turn helps to reduce the overall weight of the LED lamp.

This grade of polycarbonate is both corrosion and heat resistant, so it is not easily damaged by harsh or abrasive conditions and heat.
