CR Neoprene Rubber | Chloroprene Rubber | Neoprene O-Rings

CR Neoprene       ASTM D 2000, SAE J200 Type/Class: BC, BE

General Characteristics

Neoprene was the first synthetic rubber developed commercially and exhibits generally good ozone, aging and chemical resistance. It has good mechanical properties over a wide temperature range. Improved ozone, weathering and aging resistance compared with nitrile rubber.

AKAs: Chloroprene

Temperature Properties

Heat Heat Resistance Up to approximately 250°F (121°C).
Cold Cold Flexibility Down to approximately -40°F (–40°C).
