## Tflex 600 Series Thermal Gap Filler 

## Product Description 

Tflex[TM] 600 is an exceptionally soft, highly compliant gap filling interface pad with a thermal conductivity of 3 W/mK. These outstanding properties are the result of a proprietary boron nitride filler in the composition. 

The high conductivity, in combination with extreme softness produces incredibly low thermal resistances. 

## *Ready for 5G 

Tflex 600 is naturally tacky and requires no additional adhesive coating that can inhibit thermal performance. Tflex 600 is electrically insulating, stable from –45°C to 200°C and meets UL 94 V0 rating. 

## FEATURES AND BENEFITS 

- Very high compliancy for low stress applications 

- 3 W/mK thermal conductivity 

- Available in thicknesses from 0.020” - 0.200” (0.5mm - 5.0mm) 

- Naturally tacky, needs no further adhesive coating
