CHEMICAL AND PHYSICAL PROPERTIES
| Physical Description | 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. |
