Suspension Polyvinyl Chloride (S-PVC)

 

Suspension Polyvinyl Chloride (S-PVC) is a major form of PVC resin.

It is manufactured through suspension polymerisation of Vinyl Chloride Monomer (VCM) in an aqueous medium.

Uses

S-PVC is widely used for:

  • PVC pipes

  • Irrigation systems

  • Electrical conduits

  • Construction products

  • Plumbing

  • Sanitation infrastructure.

In 2026, the DGFT imposed a six-month restriction on imports of S-PVC resin, affecting a key input used by the pipe-manufacturing industry.

Key Pointers

  • S-PVC = Suspension Polyvinyl Chloride.

  • Raw material → Vinyl Chloride Monomer.

  • Process → Suspension polymerisation.

  • Major use → PVC pipes.

  • Other PVC processes: suspension, emulsion, bulk and solution polymerisation.

  • Important for GS-III → manufacturing, imports, MSMEs and trade policy.
