Product Description

Tflex

600 is an exceptionally soft, highly compliant gap filling interface pad with a thermal

conductivity of 3 W/mK. These outstanding properties are the result of a proprietary boron

nitride filler in the composition.

The high conductivity, in combination with extreme softness produces incredibly low thermal

resistances.

Tflex 600 is naturally tacky and requires no additional adhesive coating that can inhibit thermal

performance. Tflex 600 is electrically insulating, stable from –45°C to 200°C and meets UL 94 V0

rating.

FEATURES AND BENEFITS

• 3 W/mK thermal conductivity

• Available in thicknesses from 0.020” - 0.200” (0.5mm - 5.0mm)

• Naturally tacky, needs no further adhesive coating
