As part of its commitment to the growing LED (light-emitting diode) lighting market, Bayer MaterialScience LLC has introduced a new grade of polycarbonate resin to its already extensive portfolio. The new grade, Makrolon® LED2243, was developed as a UV-stabilized, high-light transmission addition to Bayer MaterialScience’s existing materials for LED applications.

Bayer MaterialScience already offers several grades of polycarbonate for the LED market that feature very high light transmission, high thermal stability, excellent stability under high LED flux and clear flame retardant properties. All of the grades offer specific characteristics ideal for a variety of LED applications.

These grades include:
• Makrolon LED2243 – The latest addition to Bayer MaterialScience’s LED product portfolio was designed to resist UV light, and to offer superior clarity for optic and lens applications.
• Makrolon LED2045 – The highest light transmittance product, ideal for refractive optics, lenses, and light pipes and guides.
• Makrolon LED2245 – Similar to LED2045 – with slightly improved physical properties and lower melt flow index.
• Makrolon FR7087 – Believed to be the first clear polycarbonate that passes UL 94 5VA flame rating. Ideal for lenses, covers and optical components.
