In practice, CR is very often familiar under trade names like e.g. Neoprene (DU PONT). CR has rather balanced characteristics. Through the corresponding protective means, a rather good ozone and ageing resistance and a satisfactory oil resistance can be achieved. As opposed to NR, a high mechanical value can also be reached “unfilled” with CR and the other synthesis rubber types. Due to its high chlorine contents, CR is flame retardant. It burns within a flame but is extinguished if the flame is removed.
CR is for Shore-hardness Shore A 25-90 available.
Areas of application: Everywhere where flame resistance, good ageing characteristics as well as chemical resistance are necessary, like e.g. conveyor belts, seals, hoses, roller covers, container coatings.
