The CAS number of PVC is 9002-86-2, the EINECS number of PVC is 208-750-2, the chemical formula of PVC is -[CH2CHCl]-n, the melting point of PVC is 302, the refractive index of PVC is 1.54 (20 C), and the density of PVC is 1.4 g/mL at 25 °C(lit.).
PVC is a PVC plastic, it has bright color, corrosion resistant, durable, due to the increase of plasticizer, anti aging agent and some other toxic auxiliary materials in the process of manufacturing, so the products is generally not store food and medicine.
PVC is a kind of Vinyl Polymer material. Simply put, the aqueous solution of salt in the current chemical decomposition. This process produces chlorine, caustic soda and hydrogen. Refining, oil or gasoline is to produce ethylene cracking. When the chloride and ethylene after mixing, will produce Dichloroethylene, Dichloroethylene and vinyl chloride can be converted to produce, it is a basic component of Polyvinyl Chloride. The polymerization process of vinyl chloride molecules together can form the PVC chain. Polyvinyl chloride generated in this way as a white powder. It can not be used alone, but can be mixed with other ingredients to generate a lot of products.
PVC is rich in raw materials (oil, limestone, coke, salt and natural gas), mature manufacturing technology, low price, a wide range of uses and other prominent features, has become the second common resin the world second only to polyethylene resin, accounted for 29% of total consumption of synthetic resins.
PVC is easy to process, can be processed by molding, lamination, injection molding, extrusion, calendering, blow and so on. PVC is mainly used for the production of artificial leather, film, cable sheathing and other soft plastic products, also produces lumber, doors, windows, pipes and valves and other hard plastic products.
PVC flame ( flame retardant is more than 40 ), high chemical resistance ( resistance to concentrated hydrochloric acid at a concentration of 90% sulfuric acid concentration of 60% nitric acid and sodium hydroxide concentration of 20% ), the mechanical strength excellent electrical insulating properties and advantages. But its poor heat resistance, softening point is 80 ℃, color begins to decompose at 130 ℃ and precipitation HCI.
