Suspension Polyvinyl Chloride

Suspension Polyvinyl Chloride Latest News

Recently, the Directorate General of Foreign Trade (DGFT) imposed a six-month restriction on imports of a Suspension Polyvinyl Chloride (S-PVC) resin which is a key input used for manufacturing of pipes. 

About Suspension Polyvinyl Chloride

• It is a polymer manufactured from vinyl chloride monomer.
• It is produced through polymerisation of vinyl chloride monomer (VCM) in aqueous medium with the use of initiators and additives ensuring controlled molecular weight and particle morphology. 
• Poly(vinyl chloride) resins are produced by four basic processes: suspension, emulsion, bulk and solution polymerization.
  • PVC suspension resins are usually relatively dust-free and granular with varying degrees of particle porosity.
  • PVC emulsion resins are small particle powders containing very little free monomer.
  • Bulk PVC resins are similar to suspension PVC resins, though the particles tend to be more porous.
  • Solution PVC resins are smaller in particle size than suspension PVC with high porosity particles containing essentially no free monomer. 
• Applications: S-PVC resin is used across sectors, from irrigation pipes and conduits to electrical wires used in construction.
