SABIC Innovative Plastics ammonia-resistant Lexan DMX extends product life of Norka’s energy

Date Announced: 27 Aug 2010

Pittsfield, Mass. — Norka, a leading German lighting manufacturer, chose SABIC Innovative Plastics’ extreme-performance Lexan* DMX polycarbonate (PC) copolymer resin for its new line of Luzern 38 tubular luminaires with light-emitting diodes (LEDs). Lexan DMX resin can withstand the hostile, ammonia-rich environments of stables, zoo cages and other animal enclosures, enabling Norka to create a distinctive lighting product for this niche market. Unlike traditional PCs, new Lexan DMX resin provides exceptional clarity and resistance to haze/reduced light transmission and embrittlement from prolonged ammonia exposure for extended luminaire life and reduced energy consumption. With this unique application, Norka and SABIC Innovative Plastics have strengthened their longstanding relationship and demonstrated the market value of continuous innovation in the PC copolymer arena.

Norka previously made luminaires with incandescent bulbs and standard PC; however, the fixtures had to be discarded after about a year when the bulbs burned out and the plastic had become hazy from ammonia. With the goal of creating an environmentally responsible luminaire with better energy performance and extended life, the company turned to LEDs – and needed a better plastic that could match their long lifespan.

“Norka takes pride in technology leadership and we seek out suppliers that share our commitment to the latest innovations with the best materials available,” said Martin C. Stäcker, CEO, Norka. “That’s one reason why we have collaborated for many years with SABIC Innovative Plastics. Another reason is their ability to quickly provide specialty solutions – like new Lexan DMX resin – for a wide range of unique lighting products. We know we can always rely on SABIC Innovative Plastics to meet our exact requirements, no matter how demanding.”

“This specialized application for Lexan DMX resin showcases important strategic initiatives at SABIC Innovative Plastics,” said Rob de Jong, product market leader Europe, Lexan copolymer resins, SABIC Innovative Plastics. “We are continuing to invest in our extreme performance portfolio of Lexan copolymer resins to give customers like Norka fresh and exciting design options to differentiate their products, expand into new markets and increase overall quality and performance. We are also focusing on innovative materials that can enable the design of sustainable applications, such as energy-efficient LED lighting.”

Superior Performance vs. PMMA and Standard PC

Norka initially tried polymethyl methacrylate (PMMA) for the Luzern LED luminaire but found that this material did not provide a high enough heat deflection temperature (HDT) or sufficient impact resistance, or perform as well as desired on the Glow Wire Ignition Test (GWIT). In contrast, Lexan DMX copolymer provides a GWIT of 850C, a key requirement for lighting applications in some countries such as France to fulfill the railway norm in combination with better toughness.

Lexan DMX resin provides a pencil hardness of H, 2.5 times the surface hardness of standard PC, as well as excellent scratch resistance without requiring specialty coatings. When exposed to ammonia vapor, Lexan DMX resin retains its transparency, smooth surface finish and ductility, resulting in a luminaire that continues to look good, transmits light effectively and avoids brittleness that could pose a safety hazard.

For the Luzern luminaire, the water-clear SABIC Innovative Plastics material is extruded into a long tube to enclose the LED light strip.

Other potential applications for Lexan DMX copolymers are keypads and touch screens for electronics, bezels for televisions and notebooks, lenses, and coextruded film and sheet for scratch protection.

SABIC Innovative Plastics will be showcasing its expanding portfolio of high performance materials for the LED industry at K’ 2010. Norka’s Luzern 38 tubular luminaires with LEDs, along with other new applications will be highlighted, demonstrating SABIC Innovative Plastics commitment to the LED industry.
