CHEMICAL AND PHYSICAL PROPERTIES
| Physical Description | Vinyl chloride appears as a colorless gas with a sweet odor. Easily ignited. Shipped as a liquefied gas under own vapor pressure. Contact with the unconfined liquid may cause frostbite by evaporative cooling. Leaks may be liquid or vapor. Vapors are heavier than air. May asphyxiate by the displacement of air. Under prolonged exposure to fire or intense heat the containers may rupture violently and rocket. Suspected carcinogen. Used to make plastics, adhesives, and other chemicals. |

| Melting Point | -245 °F (NTP, 1992) |
| Flash Point | -110 °F (NTP, 1992) |
| Solubility | Slightly soluble (NTP, 1992) |
| Density | 0.969 at 8.6 °F (USCG, 1999) - Less dense than water; will float |
| Vapor Density | 2.21 (NIOSH, 2023) - Heavier than air; will sink (Relative to Air) |
| Vapor Pressure | 3877.5 mmHg (USCG, 1999) |
| LogP | log Kow = 1.46 |
| Henry's Law Constant | Henry's Law constant = 0.0278 atm-cu m/mole at 25 °C |
| Stability/Shelf Life | An unstable polyperoxide is apparently formed in vinyl chloride through oxidation by atmospheric oxygen in the presence of any of a variety of contaminants. Storage under these conditions for a long period increases the concentration of unstable polyperoxide to hazardous levels. |

PRODUCT INTRODUCTION
description
Vinyl chloride is a colorless gas. It burns easily and it is not stable at high temperatures. It has a mild, sweet odor. It is a manufactured substance that does not occur naturally. It can be formed when other substances such as trichloroethane, trichloroethylene, and tetrachloroethylene are broken down. Vinyl chloride is used to make polyvinyl chloride (PVC). PVC is used to make a variety of plastic products, including pipes, wire and cable coatings, and packaging materials. Vinyl chloride is also known as chloroethene, chloroethylene, and ethylene monochloride.
