Abstract: Closed cell foams are widely used as protective garments in extreme environments. This article studied the use of neoprene-based materials in wetsuits by developing a strategy for reducing the thermal conductivity of a flexible, closed cell polychloropene foam. The thermal conductivities of the charged and unmodified neoprene foams were measured using the transient plane source (TPS) method with the Hot Disk TPS 2500 S thermal conductivity meter. It was found that a wetsuit made of ultra-low thermally conductive neoprene capable of potentially extending dive times to 2–3 hours in water below 10 °C, compared with <1 hour for the state-of-the-art wetsuits.
