Neoprene is the general purpose sheet for work that has to survive outdoors. It resists heat, ozone and weathering better than natural rubber, holds up against inorganic chemicals apart from oxidising acids and halogens, and gives moderate resistance to aliphatic hydrocarbons - enough for incidental oil contact, though not a substitute for nitrile where oil is the working medium.
Typical uses are weather gaskets and flashings, expansion joint faces, vibration pads, insulating joints, duct and plant lagging, and protective coatings for surfaces in contact with oils and chemicals. Flame-retardant grades are made, which is why neoprene turns up in plant rooms and marine work.
Trelleborg publishes a service range of -25 °C to +120 °C for its CR sheeting; the polymer limits given in the Parker O-Ring Handbook are approximately -40 °C to +121 °C. Both are polymer figures and a specific compound may be narrower. Order by hardness in Shore A, thickness and roll width.
| Material | Chloroprene rubber (neoprene) |
|---|---|
| Polymer Designation | CR |
| Temperature Range | -25 °C to +120 °C for CR sheeting. The Parker O-Ring Handbook gives the CR polymer limits as approximately -40 °C to +121 °C. A particular compound may be narrower. |
| Chemical Resistance | Good resistance to heat, ozone and weathering; moderate resistance to aliphatic hydrocarbons; resistant to inorganic chemical products except oxidising acids and halogens |
| Flame Retardancy | Flame-retardant grades are available; specify at order if required |
| Sheet Width | 1 metre |
| Thickness Range Stocked | 1 mm to 10 mm |
| Supply Form | Sold by the roll, made up to 50 kg. Every roll is 1 m wide, so its length falls as the thickness rises. State the thickness and the length or area needed. |
