Polyvinyl chloride agricultural applications

Chlorinated hydrocarbons, containing one or two carbon atoms, constitute a significant fraction of the hazardous substances from industrial, domestic, and agricultural sources. In part, this is due to their high levels of production. Over five million tonnes of 1,2-dichloroethylene (1,2-DCE) are produced annually for use as a solvent and chemical intermediate [1]. Vinyl diloride (VC) is also produced in large amoimts (over three million tonnes annually) for the manufacture of polyvinyl chloride [1]. The solvents tetrachloroethylene (PCE), trichloroethylene (TCE), 1,1,1-trichloroethane (TCA), 1,1-dichloroethylene (1,1-DCE), 1,2-dichloroethane (1,2-DCA), and carbon tetrachloride (CT) have a combined annual production of over 6 million tonnes [1]. Since 1970, annual U.S. production of dichloromethane (DCM) has ranged from 212 to 286 million kg, with the principal application being paint removal [2]. 

Chlorinated PE Modifier for polyvinyl chloride (PVC) or compounded with LDPE or HDPE film to improve toughness films are used as liners and for agricultural applications, flame retardant.
