Chloroprene, stabilized appears as a clear colorless liquid. Flash point -4°F. May polymerize exothermically if heated or contaminated. If polymerization takes place inside a container, the container may rupture violently. Less dense than water. Vapors heavier than air. Used to make neoprene rubber.
Vapour pressure, kPa at 20°C: 23.2
Relative vapour density (air = 1): 3.1
Monomer for making neoprene.
