CHEMICAL AND PHYSICAL PROPERTIES
| Physical Description | Vinylidene chloride, stabilized appears as a clear colorless liquid with a chloroform-like odor. Flash point 0 °F. Boiling point 99 °F. Denser (at 10.1 lb / gal) than water and insoluble in water. Hence sinks in water. May polymerize exothermically if heated or contaminated. If the polymerization takes place inside a container, the container may rupture violently. Vapors heavier than air. |

PRODUCT INTRODUCTION
description
1, 1-Dichloroethene is an industrial chemical that is not found naturally in the environment. It is a colorless liquid with a mild, sweet smell. It is also called vinylidene chloride. 1, 1-Dichloroethene is used to make certain plastics, such as flexible films like food wrap, and in packaging materials. It is also used to make flame retardant coatings for fiber and carpet backings, and in piping, coating for steel pipes, and in adhesive applications.
