Heat Transfer Pads
An alternative to heat transfer compounds, these soft, flexible pads transfer heat from a source to a heat sink. They compress slightly to make up for surface imperfections and roughness. These pads are conformable with a slightly tacky surface that lightly adheres to both smooth and rough surfaces. Pads meet UL 94 V-0 for flame retardance.

Thermally Conductive High-Temperature Silicone Foam Sheets
Protect sensitive equipment from heat buildup with this silicone foam. These sheets are commonly used to fill gaps and damp vibration in computers, battery installations, and heat pipe assemblies. This foam has closed-cell construction, which restricts water, air, and gases from being absorbed. They have a crisscross texture that provides a nonslip gripping surface.

Circuit Board Coolers
Also known as thermal pads and thermal interface pads, these heat-dissipating pads pull heat away from electronic components. They’re often used to fill gaps between two surfaces that require thermal contact. All meet UL 94 V-0 for flame retardance.
