Gap filler transfers heat and absorbs electromagnetic waves

Fujipoly has introduced a thermal interface material that also absorbs a wide range of unwanted electromagnetic energy. The tacky, gel-like consistency of Sarcon EGR-11F makes it easy to handle and apply without requiring additional adhesive, says Fujipoly. When placed on top of a heat source, such as an IC chip, the compliant material fills any unwanted air gaps, allowing for more efficient transfer of heat to nearby components or heatsinks.

Sarcon EGR-11F also provides shielding effectiveness across a broad frequency spectrum while exhibiting a thermal conductivity of 1.0 W/m degree K (ASTM D 2326) and a thermal resistance of 1.05 degree Cin2/W at 14.5 PSI.

The versatile material is available in three sheet thicknesses of 0.5, 1.0 and 1.5mm and up to a maximum dimension of 300 x 200mm.

Sarcon EGR-11F can also be ordered in die-cut form to fit almost any application shape. Fujipoly says the material is well-suited for environments with operating temperatures that range from -30 to +120 degree C and exhibits a UL94 flame retardant rating of V-0.
