TFLEX 50000

Compliant 2.8 W/mK Thermally Conductive Gap Filler

Tflex 50000 is a compliant elastomer gap filler designed to provide excellent thermal
performance while remaining cost effective. This soft interface pad conforms well with
minimal pressure, resulting in little or no stress on mating parts. Tflex 500’s unique
silicone and filler combination has extremely low silicone extractables compared to many
other silicone interface products. Tflex 50000 meets NASA outgassing specification.

Tflex 50000 is naturally tacky, no adhesive coating is required. Tflex 50000 is electrically
insulating, stable from -50ºC to 200ºC and is certified to UL 94V0 flammability rating.
