Silicones enable LED manufacturing
The benefits of Dow Corning's optical-grade
silicones do not end at the design table. With over 70 years of experience
developing silicone-based solutions for cutting-edge applications,
Dow Corning offers today's LED industry unmatched experience and know-how
for LED module, lamp and luminaire assembly.
We bring more than just an
industry-leading portfolio of assembly materials – such as silicone adhesives,
materials. As a dedicated innovation leader, Dow Corning also brings
proven process and application expertise, a reliable global supply base, and
world-class customer service.
The combined manufacturing flexibilities
that silicones afford can help LED lighting OEMs lower the total cost of
ownership of their products. Available in a range of viscosities and cure
chemistries, our LED materials achieve good flow and reproduction in virtually
all processing techniques, from injection molding to casting and cavity
molding. In addition, innovations such as Dow Corning® Dispensable
Thermal Pads even allow manufacturers to quickly and precisely print our
materials in controllable thicknesses on complex substrate shapes.
Dow Corning® Moldable Optical
Silicones extend manufacturing
flexibilities further. Able to serve as both an encapsulant and optical
element, these advanced silicones process at far lower temperatures than glass
or plastic materials and, therefore, less energy to fabricate solid optical
Also, unlike plastics, Moldable Silicones
don't need to remain in the mold for long periods to prevent warping, helping
to reduce cycle time – particularly for large parts. Shorter cycle times can
often translate into lower cost since the length of time a part remains in the
machine can represent an important percentage of its total cost – depending on
the mold, optical part design and other processing factors.
The natural high heat resistance of many
Dow Corning® brand silicones easily withstands the extreme reflow
temperatures of lead-free solders used to assemble LED packaging
and surface mounts. Combined with their very low moisture absorption, this
thermal stability allows silicones to withstand the multiple processing steps
necessary to fabricate finished LED lamp and
More than a world-class materials
