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 MaterialSciences LED product portfolio was designed to resist UV light, and to offer superior clarity for optic and lens applications.
• Makrolon LED2045 — Our 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.
"Bayer MaterialScience is always developing new products for LED applications because we understand this growing market will continue to demand superior engineered materials," said Gerald DiBattista, market segment leader, IT, Electrical/Electronics Polycarbonates, Bayer MaterialScience LLC. "Our goal is to Provide OEMs with materials that offer the highest clarity and quality for their applications and to be the plastics materials solution provider for the entire LED system, not just the premier optical materials supplier. We are pleased to be able to offer these specialty grades for the LED Industry."
In addition to the optical LED grades listed above, Bayer MaterialScience offers products for LED enclosures and housings, products with excellent diffusion properties that can hide hot spots while transmitting high levels of light, and highly reflective products that can eliminate secondary process operations, according to DiBattista. "It does not matter if your application is for general illumination or a specialty lighting application, if you need an optic or a diffuser, Bayer MaterialScience has the products and the industry experience to make your LED project successful."
