Resins offer broad colour pallette and special effects for LED lighting

15 April 2010

SABIC Innovative Plastics has launched its new Expression 2011 palette offering an array of resin colours and special effects for enhancing LED light. Lexan Visualfx resins in three neutral white colours - Minor Vision, Midway Gauzy and Mighty Pure - offer three different levels of transparency and light scattering. Opalescent colours of Lexan SLX resin in pale blue tones further reduce light transmission for a softer look.

Colour punch is delivered with high-chromatic Lima and Icy Mango shades in Lexan EXL Visualfx resin, while strong, dense hues are displayed in Cerulean (medical-grade transparent Lexan resin), and Emerald Forest and Venetian Cherry (optical-grade transparent Lexan resin). Colours can be matched to the CIE 1931 xyY Chromaticity Diagram.

In addition to developing the Expression 2011 palette for aesthetics, SABIC Innovative Plastics provides a wide range of special resins and compounds that help to raise the performance and extend the useful life of LEDs. For example, the company’s Extem resin portfolio of amorphous thermoplastic polyimide (TPI) and polyetherimide (PEI) resins provide high thermal resistance and are inherently flame retardant without use of halogenated additives. LNP Konduit compounds, with exceptional conductivity performance, can conduct heat away from LEDs into a heat sink or the surrounding air.

Halogen-free flame-retardant LNP Starflam compounds offer insulating properties and can be formulated to meet electrical standards, such as the IEC 50595 glow-wire test. Transparent Lexan XHT resin offers higher thermal performance than standard polycarbonate, making it suitable for many clear lighting applications.
