Aeroflex S40B

Aeroflex S40B is a compliant elastomeric thermal interface material designed to provide excellent thermal performance with economical cost. Its soft interface pad conforms well to minimal pressure, resulting in little or no stress on mating parts. It has extremely low silicone extractable ability compared to many other silicone interface products and also meets NASA outgassing specification. Aeroflex S40B is super- flexible, high-performance design-in material, and no adhesive coating is required. It is electrically insulating, stable from - 60ºC to 200ºC and is certified to UL-94 V0 flammability rating.
