Explore the benefits of silicone optics
Moldable optical silicone elastomers offer unprecedented possibilities crossing the boundaries of thermoplastics and glass optics. Explore other benefits across our case studies and support resources.
Dow’s moldable optical silicones deliver high light transmission and low absorbance from UV to near-infrared. Unlike alternatives that rely on stabilizers, they are inherently UV and heat stable, helping maintain long-term optical clarity and performance.
Dow’s moldable optical silicones combine flexibility, toughness, and high elongation with a range of hardness options. They support complex designs, reduce weight through lower density, and offer good impact and scratch resistance.
Dow’s optical silicones can be co-molded with other silicones or overmolded onto thermoplastics and metal inserts. Mechanical interlocking or primer-assisted chemical bonding provides reliable integration across material interfaces.
Dow’s two-part, heat-curable liquid optical silicones feature low viscosity for excellent mold flow. Compatible with standard Liquid Injection Molding (LIM), they enable complex part geometries and precise replication of engineered surface features.
Dow’s silicone optics can be secured using mechanical fastening, Dow silicone adhesives such as DOWSIL™ 744 or DOWSIL™ 7091, and DOWSIL™ 3140, or integrated into a pick-and-place reflow process.
Used by major automotive and industrial OEMs, Dow’s moldable optical silicones have been tested for weathering, impact, abrasion, chemical resistance, flammability, and ingress to help meet UL, AMECA, SAE, and FMVSS requirements.
