Tflex 300 Series
Thermal Gap Filler
Product Description
Tflex 300, at pressures of 50psi, will deflect to over 50% the original thickness. This high rate of
compliancy allows the material to totally blanket the component, enhancing thermal transfer.
The material has a very low compression set enabling the pad to be reused many times.
Tflex 300, in achieving its stellar compliancy, does not sacrifice thermal performance. With a
thermal conductivity of 1.2 W/mK, low thermal resistances can be achieved at low pressures.
Tflex 300H is offered with a hard, metallized liner option for easy handling and improved
rework. The metallized liners lower coefficient of friction also allows for easy assembly of parts
*Ready for 5G
that must slide together, such as a card into a chassis.
Tflex 300TG is offered with a cut-through resistant Tgard silicone liner. The TG liner offers a
guaranteed dielectric barrier, and easier part handling for mass production.
