Rubber selection can be intimidating as there are a number of engineered high performance linings which can have several different applications. I will list a few different elastomers and durometers as a general guideline.
There can be many different formulations of the compounds listed below with different physical properties than what is listed.
Soft Natural Rubber, 30-60 Duro Shore A, Temp Limit 160 Deg F, Resistance to Hydrocarbons Poor
Typical Uses: Acid Storage depending on concentration, Transportation equipment, Abrasive Services, Sulphur dioxide scrubbers.
Semi Hard Natural Rubber, 80-85 Duro Shore A, Temp Limit 180 Deg F, Resistance to Hydrocarbons-Fair
Typical Uses: Chemical Processing and Plating
Hard Natural Rubber, 90-100 Duro Shore A, Temp Limit 200 Deg F, Resistance to Hydrocarbons-Fair
Typical Uses: Chemical Processing, High temperature nickel-copper plating, steel pickling, vacuum service.
Graphite Loaded Hard Rubber, 90-100 Duro Shore A, Temp Limit 212 Deg F, Resistance to Hydrocarbons-Fair
Typical Uses: Special lining for wet chlorine gas, in chlorine cells and associated equipment. High wear applications.
Three-ply (Soft, Hard, Soft) 40-50 Duro Shore A, Temp Limit 230 Deg F, Resistance to Hydrocarbons-Fair
Typical Uses:Steel pickling lines, Phosphoric Acid
Neoprene 40-70 Duro Shore A, Temp Limit 230 Deg F, Resistance to Hydrocarbons-Very Good
Typical Uses: Chemical or abrasive services with oil present, best for strong bases, good weather resistance, fire retardant.
Nitrile, 60-90 Duro Shore A, Temp Limits 200 Deg F, Resistance to Hydrocarbons-Excellent
Typical Uses: Aliphatic hydrocarbons, kerosene, animal, vegetable and mineral oils.
Butyl, 50-75 Duro Shore A, Temp Limits 225 Deg F, Resistance to Hydrocarbons-Fair
Typical Uses: Oxidizing acids, 70 percent hydrofluoric acids, super phosphoric acid, best water resistance, good for alternative service.
Chlorobutyl, 40-60 Duro Shore A, Temp Limits 200 Deg F, Resistance to Hydrocarbons-Fair
Typical Uses: Much the same as butyl but easier to apply and faster curing, sulfur dioxide scrubbers.
EPDM, 40-60 Duro Shore A, Temp Limits 180 Deg F, Resistance to Hydrocarbons-Poor
Typical Uses: Hypochlorite bleach, ozone and weather resistant.
