Optically clear material meets demands for LED

Shin-Etsu Silicones of America, a US Subsidiary of Shin-Etsu Chemical Co. Ltd., Japan, has risen to the challenge of producing a material that can stand up to the rigorous demands of LED applications.

Shin-Etsu's new optically clear LIMS (Liquid Injection Molding System) X-34-1972-3 material has a transparency of 95 per cent and is uniquely engineered for expanding LED applications in street lighting, automotive, and exterior illumination. Notably, its superior high temperature resistance compared to thermoplastic resins allows molded silicone optics to be positioned in close proximity to the LED light source without yellowing or cracking over extended operating life spans.

North America Marketing Manager Eric Bishop said: "Next-generation HBLED systems are getting hotter as light output continues to increase. The advanced engineering properties of our X-34-1972-3 material delivers unparalleled heat resistance and clarity at these higher operating temperatures."

Bishop also noted that the material has been tested in-house and by customers with promising results.

The optically clear LIMS X-34-1972-3 material will be on display during Shin-Etsu Silicones of America's open-house demonstration at its LIMSTM Technical Center in Akron, Ohio on Monday, October 12th (1.00 pm – 5.00 pm local time). The informal event will feature the production of 100 per cent silicones magnifying lenses and the opportunity to network with industry suppliers and associates.
