Thermal interface materials

Nothing shortens lifespan more than heat … and LED electronics generate a lot of it. By designing with DOWSIL™ thermal interface materials, you have more heat management options. Thermal Adhesives form thermally stable bonds to most LED PCB substrates and deliver excellent thermal conductivity. Their low volatility means no adverse impact on components or light output. Dispensable Thermal Pads allow you to quickly and precisely print thermally conductive silicone pads in controllable thicknesses on complex substrate shapes. They offer you enhanced thermal
performance and can accelerate production and, in many cases, reduce system costs.

  • DOWSIL™ TC-5629 Thermally Conductive Compound

 

Moldable optical silicones

You will find an unprecedented level of design freedom with moldable optical silicones from Dow. They allow you to explore more complex architectures – often while simplifying the manufacturing process.

They can also boost the long-term performance of your design. Not only do they offer excellent optical properties, they are more resistant to impact damage and degradation from UV, heat and environmental extremes than traditional optical materials – delivering high lumen density while remaining stable over time.
