Chloroprene rubber (CR) is more commonly know by the trade name Neoprene®.

Chloroprene is unusual in that it is moderately resistant to both petroleum oils and weather (ozone, sunlight, oxygen). This qualifies Neoprene® for O-ring service where many other elastomers would not be satisfactory. It is also used extensively for sealing refrigeration fluids. FDA grades are available. Neoprene® has good compression set characteristics, abrasion resistance, and a temperature range of -65º to 285ºF (-55º to 140ºC).

PAI offers Neoprene® compounds in a hardness range of 40 to 90 durometer. Black is the standard color, but many other colors are available.
