Moldable Optical Silicones
for LED Lighting


Bring more light to any design

Design a more stunning office lobby installation. Create a more perfect lens. Whatever your application, it’s now possible to bring more shine to every lighting design with moldable optical silicone from Dow Corning. Learn more about the design freedom offered by silicone optics.

These transparent, lighter-than-glass materials are soft enough to allow your innovative design combined with integrated functionality of the optical parts. They deliver good ultraviolet (UV) resistance, minimize yellowing and resist scratching, especially in comparison to PC and PMMA plastics. They also mix easily with additives to meet your specific design needs and performance goals.

LFI Technical Innovation Award

Award-winning innovation
Dow Corning’s line of optical moldable silicones was honored with not one, but two LIGHTFAIR® International (LFI®) Innovation Awards® at the world’s largest annual architectural and commercial lighting trade show and conference. Find out more about this prestigious recognition.

The shape of tomorrow
Dow Corning® brand moldable silicones are what today’s LED innovators need to forge the future of lighting with design-empowering features and benefits:

  • A low viscosity before cure makes molding into complex shapes easier than with either organic polymers or glass.
  • This may help reduce manufacturing costs and cycle times in injection molding and other processes, and potentially reduce system costs for LED-illuminated lamps and luminaires.
  • Innovative designs, not currently feasible with other known commercial products, are now possible.
  • Moldable silicones are suitable for a range of applications, such as secondary lenses, light pipes, light guides and other optical components.

Unmatched heat resistance
Compared to many organic materials, the chemical backbone of silicones makes them particularly well-suited to manage the increasingly high temperatures of today’s and tomorrow’s LED lighting systems. Our moldable optical silicones feature outstanding heat resistance—currently up to 150 °C, and pushing toward 200 °C.

With fewer heat-related limitations, optical moldable silicones give designers greater opportunity to innovate and take LED lamp and luminaire designs to the next level.
