​Application Fields Of Vinyl

Poly (vinyl chloride) is characterized by abundant raw materials (oil, limestone, coke, salt and natural gas), mature manufacturing process, low price and wide use. It has become the second largest general resin in the world after polyethylene resin, accounting for 29% of the total consumption of synthetic resin in the world. Polyvinyl chloride is easy to process and can be processed by molding, lamination, injection molding, extrusion, calendering, blow molding and other methods. PVC is mainly used to produce plastic soft products such as artificial leather, film and wire sheath, and also can produce plastic hard products such as plates, doors and windows, pipes and valves.

Polychloroethylene has the advantages of flame retardancy (flame retardance value of more than 40), high chemical resistance (resistance to concentrated hydrochloric acid, sulfuric acid with concentration of 90%, nitric acid with concentration of 60% and sodium hydroxide with concentration of 20%), good mechanical strength and electrical insulation. However, its heat resistance is poor, the softening point is 80 ℃, and it begins to decompose and discolor at 130 ℃, and HCI precipitates.
