Tflex
™
600 Series
Thermal Gap Filler
EXCEPTIONALLY SOFT, HIGHLY COMPLIANT GAP FILLER
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
• Very high compliancy for low stress
applications
• 3 W/mK thermal conductivity
• Available in thicknesses from 0.020” - 0.200”
(0.5mm - 5.0mm)
• Naturally tacky, needs no further
adhesive coating

products.
TACKY ONE SIDE ONLY
Tflex™ 600 is naturally tacky on both sides. Tflex™ 600 can be provided tacky on one side only.
This is indicated by the suffix “DC1”. This option offers good separation properties allowing the
tacky side to stick to the heatsink/chasis/cold plate/etc. and the other “dry” side to release easily
from the component(s).
REINFORCEMENT
Fiberglass is required in 0.020” (0.51mm) and 0.030” (0.76mm). Thicknesses of 0.040” (1.02mm)
and above do not require reinforcement. Data for design engineer guidance only. Observed
performance varies in application. Engineers are reminded to test the material in applicatio
n.
