also: chloroprene

Neoprene is the trade name used by DuPont Performance Elastomers. A synthetic rubber that is produced by polymerization of chloroprene.

Sedochemicals produces sheets of Neoprene in the following qualities. For most of our sensors we use 1.5 mm (1/16 inch) thick HS quality neoprene with standard polyester jersey fused to either side.
Check the Sedochemicals website for details on the different qualities, which mainly differ in softness and stretchiness. LS, S, HS, HHS, NF, W.

Super thin 0.5 mm thick neoprene with fabric fused to either side is hard to find, but extremely nice to work with. Foamorder stocks 0.5mm thick neoprene, though not in all colours, so be sure to ask what their current stock is, otherwise they might tell you that they don’t have what you are looking for.
