Polyvinyl chloride (PVC)

DianXieYan water provides almost the same amount of chlorine and caustic soda, and then chloride and ethylene reaction generating ethylene dichloride, turn to take off the chlorine hydride generation of vinyl chloride monomer.

At present, most of the vinyl chloride is by oxychlorination process production, vinyl chloride in usually environmental condition is gas, under pressure to become colorless transparent liquid.

manufacturing

At present PVC resin estimate production capacity of 11.1 billion pounds, mostly homopolymer and a small amount of copolymer. Accounts for about 90% of the total amount by suspension method have a, the rest for bulk polymerization and emulsion for legal system, the king some paste resin. But a small amount of solution copolymer is not included.

The product widely potential application scope, is in the polymerization process。
