PRODUCT DESCRIPTION
Tflex™ SF10 is an innovative, high performing thermal material in Laird’s gap
filler portfolio. This silicone free material measures 10 W/mk and has excellent
deflection properties which provides minimal pressure on components during
deflection. Very little pressure is required to reach the lowest possible thermal
resistance.
FEATURES AND BENEFITS
Silicone free formulation
Low peak and residual pressure
Excellent surface wetting for low contact resistance
Exceptionally low thermal resistance
No Fiberglass reinforcement
Environmentally friendly solution that meets regulatory requirements
including RoHS and REACH
