Dow Corning are announcing new silicone optical resins with highly favourable optical properties under high temperature. The supplier say the new resins can be easily molded into complex shapes, thick and large parts, and even undercuts.
The properties of Dow Corning® MS-1002 and Dow Corning® MS-1003 Moldable Silicones allow these feats, which are difficult to create with other optical materials. Applications include secondary optics to diffuse, focus and distribute light, light pipes, and light guides in LED lamps & luminaires. The combination of high temperature resistance, UV resistance and resistance to yellowing can enhance lumen maintenance. Because of their heat and photo stability, optics made with MS-1002 and MS-1003 can touch the LEDs without an air gap, boosting efficiency and overcoming typical issues with optics made of plastic materials.
Addressing the diverse needs of the complex lighting market, Dow Corning are developing multiple versions targeting specific designs and applications. These materials exhibit good mold flow for excellent feature reproduction, and easy mixing with additives like phosphor. Dow Corning lighting experts support manufacturers to develop new secondary optics designs and to process moldable silicones, bringing the benefits of silicone technology to the lighting industry.
