Polyvinyl Chloride (PVC)

Brief Overview

Polyvinyl chloride resin, abbreviated as PVC resin, is a white powder used to produce plastics and rubbers. It is used to produce thermoplastic resins that are more versatile than other existing thermoplastic materials in processing and applications. This polymer can be considered a unique raw material that can be made into a wide range of products, from soft and soft to light and rigid. In addition, PVC resin has good chemical stability and is corrosion-resistant and water-resistant. It has good solubility, electrical insulation, thermoplasticity, and membrane-forming ability.

Manufacturing Process

PVC (glass transition temperature: 70-80°C) is produced by the polymerization of vinyl chloride monomer (VCM). Vinyl chloride monomer (VCM) is produced from the chlorination of ethylene and pyrolysis of the resulting ethylene dichloride (EDC) in a cracking unit. The popular methods used to manufacture PVC commercially are Suspension PVC (S-PVC) and Bulk or Emulsion (E-PVC). Suspension Polymerization accounts for 80% of PVC production worldwide.

Plastic Industry 

PVC resin transparent film can be used in greenhouses, plastic greenhouses and plastic film. It can also be used for bags, raincoats, tablecloths, curtains, inflatable toys, etc. It can also be used to make hoses, cables, wires, plastic sandals, shoes, slippers, toys, auto accessories, etc.

Other Applications 

PVC resin can be used to make leather luggage, leather bags, book covers, sofas and car seats, as well as floor covering and floor materials for buildings.
