Vinyl Chloride Monomer, VCM
Vinyl chloride Monomer, VCM is a chlorinated organic compound with the formula CH2 = CHCl, which is also called CM. Vinyl chloride Monomer, VCM colorless substance is one of the most important industrial chemicals used in the production of polyvinyl chloride (PVC). Vinyl chloride Monomer, VCM at medium temperature and pressure, vinyl chloride is in a gas state. Vinyl chloride Monomer, VCM is a highly toxic, highly flammable and carcinogenic substance. PVC is obtained from the polymerization of the vinyl chloride monomer radical.

Physical properties of Vinyl Chloride Monomer, VCM
VCM is a colorless gas, it is extremely flammable and unstable. It has a mild, sweet odour. The threshold for detecting odour is 3000 parts per million. VCM is soluble in many organic solvents but is not soluble in water. VCM is considered a volatile organic compound by the National Pollutant Inventory.
Vinyl Chloride Monomer, VCM usage
Vinyl Chloride Monomer, VCM is the key chemical precursor to PVC. It is produced commercially by combining a hydrocarbon feedstock, namely ethylene, obtained by cracking natural gas or petroleum, with elemental chlorine.
PVC is used to make a variety of products, including plastics, hoses, pipes and fittings for outdoor irrigation, wire and cable coatings, packaging materials, furniture and automobile upholstery, flooring, windows, credit or ATM cards, wall coverings, housewares, outdoor furniture, plastic containers, wrapping film, automotive parts and many others. In the past VCM has been used as a refrigerant.
The use of Vinyl Chloride Monomer,
VCM is increasing. VCM is used in the manufacture of plastic pipes - covering cables and wires and flooring, film photography and also in the automotive industry. Monomer vinyl chloride VCM is an essential ingredient. Chlorine is derived from brine – a solution of common salt and water. Since both raw materials are inexpensive, readily available commodities. Chlorine also has excellent inherent flame-retardant properties that are directly passed on to vinyl end-products, such as electrical conduit and wiring, which require high resistance to flame.
Vinyl chloride monomer (VCM)
Vinyl chloride monomer (VCM) is one of the world’s most important and largest commodity chemicals. VCM is used primarily for the production of polyvinyl chloride (PVC) homopolymer and copolymer resins. The vinyls chain, comprising ethylene dichloride (EDC), vinyl chloride monomer (VCM), and polyvinyl chloride (PVC), is a key component of the global petrochemical and thermoplastics sectors.
when you work whit Vinyl chloride monomer (VCM)
Vinyl chloride monomer (VCM) can polymerise rapidly due to heating and under the influence of air, light and contact with a catalyst, strong oxidisers and metals such as copper and aluminium, with fire or explosion hazard. As a gas mixed with air, VCM is a fire and explosion hazard. On standing Vinyl chloride monomer (VCM) can form peroxides, which may then explode. Vinyl chloride monomer (VCM) will react with iron and steel in the presence of moisture.
Breathing high concentrations of Vinyl Chloride Monomer, VCM fumes for a short time may cause headaches, dizziness, sleepiness, unconsciousness, and at extremely high levels, can lead to death. Breathing Vinyl Chloride Monomer, VCM fumes over a long period of time (many years) can result in impotence, permanent liver damage, immunological dysfunction and nerve damage.If Vinyl Chloride Monomer, VCM is spilt on the skin, VCM will cause numbness, redness and blisters and will cause symptoms similar to frostbite.
