PRODUCT DESCRIPTION
Tflex™ HD700 thermal gap filler combines 5 W/mK thermal conductivity with superior pressure
versus deflection characteristics. The combination will allow minimal stress on components
while also yielding low thermal resistance. As a result, less mechanical and thermal stresses will
be experienced within your device.
Tflex™ HD700PI can be provided with an integrated polyimide film on one side. This liner
provides numerous application benefits like electrical isolation, placement ease during
assembly, and tear resistance for applications that require shear.
Tflex™ HD700 and Tflex™ HD700PI are available in thickness from 0.5mm (0.020”) to 5mm
(0.200”). The standard material Tflex™ HD700 material is a light pink color, but we do have the
option to provide this in a grey color if a neutral color is desired (Tflex HD700,GR).
Laird can provide material to meet your production needs in any region through our local
production facilities. Please contact your local Laird sales or field engineering contact for
samples or questions.
