SABIC LED resins offer improved color under heat exposure

April 4, 2012 — SABIC’s Innovative Plastics business added 3 Lexan LUX resin grades to its flagship portfolio of high-performance Lexan polycarbonate (PC) materials. The new Lexan LUX resins (Lexan LUX2110T, LUX2010T, and LUX2910T) are used in light emitting diode (LED) applications such as light guides and lenses. They are transparent and use a new formulation to improve initial color, color stability, and light transmission during heat aging.

These 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 (10 units better, compared to competitive products) after heat aging at low wavelengths typical of LED systems, according to the company.

Customers have a choice of flow characteristics for various LED applications, including automotive light guides and inner lenses and general lighting lenses. They also meet the UL 94 V-2 rating at 0.8mm and glow wire flammability index (GWFI) 850C at 1mm, according to the International Electrotechnical Commission (IEC) 60695-2-12.

The resins complement SABIC’s existing Lexan LUX resins: non-chlorinated, non-brominated FR resins that meet the UL 94 V-0 standard at 1.5 mm in all colors.
