Additional “Lexan” PC grades introduced / Improved flame retardancy at thin gauges / Light transmission levels in LEDs retained at prolonged high temperature
Sabic Innovative Plastics (Pittsfield, Massachusetts / USA; www.sabic-ip.com) has expanded its portfolio of high-performance “Lexan” PC materials with the introduction of “Lexan” CFR (clear flame retardant) copolymer and three new “Lexan” LUX resin grades. “Lexan” CFR copolymer addresses rising demand in consumer electronics and appliance manufacture for a clear, sustainable flame retardant material, and the new “Lexan” LUX resins have been developed for LED applications such as light guides and lenses.

“Lexan” CFR provides consumer electronics and appliance manufacturers with a clear material with superior flame resistance at very thin gauges, meeting the requirements of products that continue to shrink in size and thickness. For example, covers for notebook computers are typically 1.5 mm, and tablet covers are even thinner at 0.8-1.2 mm. To further assist in thin-wall design, the copolymers are claimed to offer improved flow and processability compared to standard clear, FR PC, due to effects of shear thinning.
Additional potential applications for this material include electrical transparent housing covers on refrigerators and other appliances and stationary electrical parts like display panels, buttons, switches and decoration parts.
The “Lexan” LUX resin range, which includes the three new transparent grades and three others designed for covers of LED bulbs and tubes, addresses efforts to raise the continuous operating temperature of LED lights for increased light output. The new grades (LUX2110T, LUX2010T and LUX2910T resins) utilise new technology that is claimed to offer improved initial colour, colour stability and light transmission during heat aging compared with standard PC.
Sabic said the grades retain more than 98% of initial light transmission when exposed to a temperature of 130°C for more than 5,000 hours. At more typical heat exposure in the range of 90-110 °C, the transmission retained is even higher. They also provide improved light transmission after heat aging at low wavelengths typical of LED systems.
