Gap Fillers 
(Tflex

) 
Laird gap fillers are used to bridge the interface between hot 
components and a chassis or heat sink assembly to increase the 
overall heat transfer from the system. The unique combination of 
thermal conductivity and softness reduces mechanical stress while 
maintaining thermal performance. Laird’s extensive gap filler product 
lines includes a wide range of performance capabilities, including ultra-
thin gap fillers, a high deflection series, and materials that provide 
electrical isolation.

Dispensable Gap Fillers 
(Tflex
TM
 and Tputty
TM
) 
Laird dispensable gap fillers are used to bridge the interface 
between hot components and a chassis or heat sink assembly when 
elimination of mechanical stress or bulk automated dispensing are 
critical design considerations. These materials can be dispensed to 
fill large and uneven gaps in assemblies and due to their super 
compliant nature; little to no pressure is transferred between 
interfaces. Laird’s dispensing product portfolio includes both one 
and two-part materials, as well as products specifically designed for 
vertical stability and consistent dispensing.
