Bayer MaterialScience LLC's new polycarbonate grade offers high light transmittance and UL flammability rating properties for LED lenses Replacing a long-time fixture isn't easy. But PolyBrite's Borealis® LED (light-emitting diode) lamps featuring Bayer MaterialScience LLC's Makrolon® polycarbonate plastic make it a snap to switch from an energy-sapping incandescent light bulb to energy-efficient, eye-pleasing and impact-resistant LED technology.

German Bayer MaterialScience has designed a 1.5-mm-thick Makrolon FR7067 polycarbonate plastic for LED lenses, which can meet the UL-94 V0 ratings for flame-retardant characteristic at half the thickness of most polycarbonate lenses. And it's thought that Lenses made with this material can improve light transmission efficiency to almost 90%.

With the growing trend towards the use of LEDs for innovative lamp and lighting concepts, Bayer MaterialScience has developed new grades of its transparent Makrolon® polycarbonate specifically for the production of these modern light sources.
