Combining thermally conductive polycarbonate with polyurethane offers advantages for electronics manufacturers

ORLANDO, Fla., March 24, 2015 /PRNewswire/ -- While the LED lighting market continues to grow, the relatively high price of LED bulbs has forced manufacturers to explore ways to reduce costs. Since electronic component costs are usually fixed, other components, such as the heat sink, offer an opportunity to reduce costs and improve performance through unique assembly processes.

In-mold electronic component assembly and encapsulation is possible by combining two polymer technologies – thermally conductive polycarbonate and insulating polyurethane. Doing so reduces the number of components while creating a finished part in a mold without additional manual assembly. Compared to traditional manufacturing, this process lowers labor costs and improves thermal contact by eliminating relatively low conductivity thermal interface materials (TIM).

Nicolas Sunderland, senior scientist, and Terry G. Davis, principal engineer, both of Bayer MaterialScience LLC, will present Thermally Conductive Polycarbonate for Electronics, 10 a.m., Wednesday, March 25, during the Society of Plastics Engineers' ANTEC^® conference, March 23-25 in Orlando. Jim Lorenzo, principal engineer, and Dave Rocco, senior engineer, also authored the paper.

According to Sunderland and Davis, the benefits of combining thermally conductive Makrolon^® TC8030 polycarbonate with polyurethane encapsulation technology utilizing Bayflex^® polyurethane reaction injection moling (RIM) technology include:

• reducing the bill of materials
• increasing manufacturing flexibility, and
• reducing the weight for many electronic components

As part of the presentation, they will also detail the assembly process – with a particular focus on in-mold encapsulation – and offer results of temperature and durability testing.
