Aeroflex S28


Aeroflex S28 is a compliant elastomeric thermal interface material designed to provide excellent thermal performance at competitive cost. Its soft interface pad conforms well to minimal pressure, resulting in little or no stress on mating parts. It has extremely low silicone extractables compared to many other silicone interface products and also meets NASA outgassing specification.
Aeroflex S28 is naturally tacky, and no adhesive coating is required. It is electrically insulating, stable from -60ºC to 200ºC and is certified as UL-94 V0 in flammability rating.
