21 W/m•K CF210A carbon fiber thermal gap filler

The carbon fibers allow for higher thermal conductivity while remaining compliant. SARCON CF210A’s compliance is closer to a much lower conductivity gap filler such as SARCON PG25A. While the thermal resistance of more traditional gap fillers tends to drop with compression, carbon-fiber reinforced materials like CF210A have a stable thermal resistance, regardless of compression.

This highly thermally conductive gap filler is offered in thicknesses from 1.50mm to 2.5mm in .5mm increments and is available in sheets 130mm x 130mm (suggested usable is 120mm x 120mm).
