Neoprene (CR) rubber parts
Neoprene (polychloroprene) is a general-purpose synthetic rubber with a balance of properties. It has moderate resistance to oil, good resistance to weather and ozone, good toughness, and it resists burning better than most hydrocarbon rubbers.
It is often chosen when a part sees some oil and some weather and no single condition is extreme. For heavy oil or fuel exposure, nitrile or FKM is the better choice.
At a glance
| Property | Neoprene (CR) |
|---|---|
| Also called | CR, Polychloroprene, Chloroprene rubber |
| Known for | General purpose, oil and weather resistance |

| Common ASTM D2000 type and class | BC, BE |
Typical values for general-purpose grades. The compound, the hardness and the service conditions decide what a part can take, so we confirm the compound with your quote. For what the type and class letters mean, see ASTM D2000 callouts.
