Neoprene rubber has a great performance when keeping body temperature warm/cool is needed, and it has also shock-protection and buoyant applications.
Neoprene rubber has good chemical stability, and maintains flexibility over a wide temperature range. Neoprene rubber resists degradation more than natural or synthetic rubber. It can be used as padding in external metal cases while allowing a snug fit. It resists burning better than exclusively hydrocarbon based rubbers.
