## TflexTM 300 Series **Thermal Gap Filler** 

## Innovative **Technology** for a **Connected** World 

## UNIQUE SILICONE GEL OFFERS COMPLIANCY, THERMAL RESISTANCE 

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™ 300-H is offered with a hard, metallized liner option for easy handling and improved rework.  The metallized liner’s lower coefficient of friction also allows for easy assembly of parts that must slide together, such as a card into a chassis. 

## FEATURES AND BENEFITS 

- Extreme compliancy allows material to “totally blanket” component(s) 

- Thermal conductivity of 1.2 W/mK 

- Available in thicknesses from 0.020” - 0.200” (.5mm – 5.0mm) 

- Low compression set enables the pad to be reused many times
