Bayer MaterialScience LLC works with architects, designers, engineers and lighting professionals to help bring lighting products to life by providing materials and expertise that offer light management functionality.
Bayer will highlight its robust selection of light- and thermal-managing polycarbonate plastics, films and sheet materials at its booth (#7936) during the Lightfair International trade show and conference this week, 3 to 5 June, in Las Vegas, Nevada (US).
The exhibit includes:
Makrolon LED2643 polycarbonate: For LED lighting applications requiring high lumen efficiency, excellent light transmission and stability to heat – such as optics, lenses and enclosures. The polycarbonate is impact resistant, has a UL 94 flame class rating of V-2 at 0.75 mm, and is f1 rated for outdoor use (in accordance with UL 746C).
Makrolon TC8030 polycarbonate plastic: For manufacturers looking to replace aluminum in heatsink applications for LED replacement lamps and next-generation luminaires. This thermally conductive polycarbonate grade provides corrosion resistance and increased design freedom. It has similar thermal properties when compared to aluminum but is able to reduce costs by eliminating assembly steps, improving production efficiency and reducing capital investments. Processed by injection molding, Makrolon TC8030 has a UL 94 flame class rating of V-0 at 2.0 mm and is f1 listed.
Makrolon FR7087 polycarbonate is for flame-retardant applications requiring clarity, including lenses, covers and electrical enclosures. Available in transparent and diffusion colors, Makrolon FR7087 plastic has a UL 94 flame rating of 5VA at 3.0 mm. This material was chosen by TerraGlo for the lens cover of its Alba Series luminaires, and by TerraLUX Illumination for the lens of its Line-Voltage Linear LED Light Engine.
Among its wealth of properties, the sheet material carries a UL 94 V-2 flammability performance listing and resists high temperatures while providing outstanding, uniform LED light diffusion, minimizing hot spots while maximizing light transmission.
Makrolon Lumen XT sheet also offers flexibility, along with superior impact resistance, when compared with glass and acrylic in LED fixtures. Bayer developed this polycarbonate sheet product for use in diffusion lenses in LED lighting fixtures, and can be formed into a variety of shapes to meet application and design requirements. Makrolon Lumen XT sheet is used for interior LED and conventional lighting fixtures. For example, it is found in a major correctional facility and U.S. Cellular Field (White Sox baseball park) in the form of diffuser panels for new LED fixtures.
Makrofol--These polycarbonate films are formulated for lighting applications. Makrofol light management polycarbonate film grades (LM228, LM309, and LM905) are translucent materials filled with a light-scattering agent in combination with a surface texture. These properties translate into various combinations of transmission and diffusion in order to meet end users’ light guidance and light reflection needs. Light diffusers for consumer goods and other backlight displays commonly utilize these film grades.
Makrofol LM903 polycarbonate film is a formable, opaque white extruded film that offers the very high light reflection properties needed for LCD and LED backlights and other reflector housing applications.
