Tflex™ SF7

Non-silicone Based Formulation Gap Filler

Product Description

Tflex SF7 is an innovative, high performing thermal material in Laird's non-silicone based formulation gap filler portfolio.  The non-silicone based formulation technology provides products with excellent deflection properties, providing minimal pressure on components during deflection.   Very little pressure is required to reach the lowest possible thermal resistance.  Thickness ranges from 0.5mm (0.020") to 4mm (0.160") in 0.5mm (0.020") increments available as standard.
