Property Characteristics Of Polyvinyl Chloride Resin

- Jan 23, 2018 -

Characteristics of polyvinyl chloride resin with rich raw materials (petroleum, limestone, coke, salt and natural gas), mature manufacturing process, low price, widely used and other prominent features, has become the world's second only to polyethylene resin, the next largest general resin, accounting for the world's total resin consumption of 29%. Polyvinyl chloride is easy to process, can be molded, laminated, injection molding, extrusion, calendering, blow molding hollow and other ways to process. PVC is mainly used in the production of artificial leather, film, wire sheath and other plastic soft products, can also produce plates, doors and windows, pipes and valves and other plastic hard products.

PVC has a flame-retardant (flame retardant value of more than 40), high chemical resistance (concentrated hydrochloric acid, concentration of 90% sulfuric acid, concentration of 60% nitric acid and concentration of 20% sodium hydroxide), mechanical strength and electrical insulation good advantages. But its heat resistance is poor, the softening point is 80 ℃, at 130 ℃ starts to decompose color, and precipitates the HCI.
