NEOPRENE RUBBER (CHLOROPRENE - CR)

CR rubber is also known by its commercial name Neoprene (trademark of Du Pont). It has excellent resistance to oils, ozone, sunlight and aging. Low permeability to gases. Recommended for use with gasoline and non-aromatic solvents. It offers little resistance to strong oxidants and to aromatic and chlorate hydrocarbons.
