New PC grade targets LED applications

Bayer MaterialScience LLC (Pittsburgh, PA) has added a grade to its slate of polycarbonates (PC) serving the LED (light emitting diode) lighting market, launching a UV-stabilized, high-light transmission material. Makrolon LED2243 joins a portfolio of PC for LED that reportedly provides high light transmission, high thermal stability, excellent stability under high LED flux, and clear flame-retardant properties.

Makrolon LED2243 joins a portfolio of PC for LED that reportedly provides high light transmission, high thermal stability, excellent stability under high LED flux, and clear flame-retardant properties.



The lenses pictured are one example of an application Bayer says can benefit from its Makrolon LED2243 polycarbonate. The new grade was developed as a UV-stabilized, high-light transmission addition to the company’s existing LED portfolio.

LED2243, which can resist UV light and offers clarity for optic and lens applications, joins LED2045 (highest light transmittance for refractive optics, lenses, and light pipes and guides); LED2245 (similar to LED2045 but with slightly improved physical properties and a lower melt flow index); and FR7087 (a clear PC that satisfies the UL 94 5VA flame rating).

In addition to the optical grades, Bayer provides related LED system materials for use in enclosures and housings. The materials feature strong diffusion properties that hide hot spots while transmitting high levels of light. The company also has highly reflective products that can eliminate secondary process operations. [email protected]
