Neoprene O Rings
Chloroprene Rubber (CR), widely known as Neoprene, are available in Imperial and Metic Sizes – with shore
Temperature Range: -50c upto +135c
Neoprene was one of the first oil resistant synthetic rubbers. However, it has only moderate resistance to
petroleum based oils and fuels. It can be considered as a good general purpose rubber with an excellent balance of
physical and chemical properties. It has better chemical, oil, ozone and heat resistance than natural rubber but a
rather lower level of physical properties.
Chloroprene tends to slowly absorb water and its electrical properties are poor. Its gas permeability is fairly
low and flame resistance is excellent, chloroprene being one of the few rubbers that are self-extinguishing.
Neoprene gives excellent rubber-metal bonds and good resilience. Certain grades of Neoprene may crystallise and
harden during storage although they will thaw on heating.
Chloroprene is widely used because of its wide range of useful properties and reasonable price. Typical
applications include belting, coated fabrics, cable jackets, seals and gaiters.
