In 2005, the last U.S. manufacturer of Hypalon ceased production of the synthetic rubber compound due to increased competition from cheaper alternatives. As a result, many products that previously used Hypalon have switched to other materials. One common replacement is neoprene, which is often used in wetsuits and other applications where flexibility and resistance to chemicals are required. Neoprene is more expensive than Hypalon, but it offers better heat resistance and durability. In some cases, PVC (polyvinyl chloride) or TPO (thermoplastic olefin) can be used as a less expensive alternative to neoprene.
