Bayer expands polycarbonate production for LED lighting systems
Polycarbonate material from Bayer MaterialScience is used, as a functional layer in light emitting diodes (LEDs).

FRIEDRICHSHAFEN, GERMANY: Bayer MaterialScience is seeing a growing worldwide demand for polycarbonate for the production of LED lighting systems (light-emitting diodes). The company is therefore systematically expanding its product range for this market segment.

“We are developing tailored materials that correspond to the specific requirements of various LED applications. We do this in close collaboration with all partners in the development chain for this sustainable lighting source of the future. Our focus is on both a wide variety of injection moulding and extrusion granules, such as for optical lenses, and semi-finished film and sheet products for the production of such things as light diffusers and reflectors, said Dr Klaus Reinartz, Head of the Global LED programme, Bayer MaterialScience.

The latest examples for the company’s development expertise are polycarbonates with particularly high thermal conductivity for cooling elements used for the thermal management of LEDs and a film that joins the points of light from individual LEDs to form a homogenous band of light.

The new polycarbonates for LED cooling elements, such as Makrolon TC 8030, are an alternative to aluminum. “These allow the cooling ribs to be more delicate and lighter. Unlike their aluminum counterparts, the injection-moulded cooling elements require no post-treatment, enabling cost-effective production with low energy consumption,” said Reinartz.

Bayer MaterialScience is also working on solutions for another energy-efficient lighting technology, based on so-called OLEDs (organic light-emitting diode). The company is collaborating with partners in the lighting industry to develop light extraction films for OLED luminaires.
