Neoprene Rubber(CR)


Neoprene Rubber is a versatile and economical grade of general purpose rubber able to perform in a range of sealing, lining and gasket applications. It has the formal designation Chloroprene (CR) and is black in color. Neoprene Rubber has good compatibility with oils and fuels as well as good weathering, heat and fire resistance. It is also a highly flexible rubber that is easy to work with and maintains this flexibility across a long performance life. Since other types are available, it should be noted that this information relates to our standard grade of Neoprene Rubber (both sheet and cut strip).
