Technical Document

Brief Overview

Vinyl chloride is the monomer used to create the synthetic polymer known as polyvinyl chloride, or PVC. It is a thermoplastic substance that is easily molded and sculpted into a wide range of shapes, making it a multipurpose substance with a wide range of uses. PVC is widely utilized in the plumbing, electrical, medical, and building industries and is renowned for its strength, resilience, and chemical resistance. PVC is frequently used for vinyl siding for dwellings, electrical wire insulation, and water and sewage pipelines. Additionally, it is utilized in medical equipment including blood bags and tubing.

Manufacturing Process

PVC resin is a thermoplastic polymer that is extensively utilized in numerous industries because of its exceptional chemical resistance, affordability, and longevity. The following steps are commonly included in the production of PVC resin:

  1. Vinyl Chloride Monomer (VCM) Production: When hydrogen chloride and oxygen are present, ethylene gets chlorinated to form volatile chemical monomers (VCM). After that, the generated VCM gas is cleaned and kept ready for usage in the following stage.

  2. Polymerization: The next step involves polymerizing the VCM gas using either suspension or emulsion polymerization.

  • VCM droplets are suspended in water during suspension polymerization with the help of a catalyst and a dispersion agent. The polymerization reaction is then started by heating the mixture while it is under pressure. After that, the PVC particles are dried, cleaned, and sorted into sizes.
  • Emulsion polymerization is a process that uses an emulsifier and a catalyst to disperse VCM particles in water. After that, the mixture is heated and vigorously stirred to start the polymerization process. After that, the PVC particles are dried, cleaned, and coagulated.
  1. Additives: Usually, PVC resin is mixed with different ingredients to enhance its characteristics. These additions may include fillers to lower costs and enhance mechanical qualities, plasticizers to increase flexibility, stabilizers to stop degradation during processing and usage, and pigments to add color.

  2. Processing: To make the finished product, the PVC resin is then treated using a variety of techniques such extrusion, injection molding, or calendaring.


PVC resin is a thermoplastic substance that is highly versatile and has numerous applications across multiple sectors. Typical uses for PVC resin include the following:

  1. Construction: PVC is frequently utilized in the building sector because of its affordability, weather and chemical resistance, and durability in windows, doors, pipelines, and siding.

  2. Electrical: Because of its electrical qualities and fire resistance, PVC is widely utilized in the electrical industry for wire insulation, electrical conduit, and cable insulation.

  3. Medical: PVC is transparent, flexible, and biocompatible, which makes it a useful material for medical applications such blood bags, tubing, and intravenous (IV) bags.

  4. Automotive: PVC finds employment in the automotive sector in a number of applications, including door panels, wiring insulation, and dashboard components.

  5. Consumer goods: PVC's affordability, flexibility, and water resistance make it a popular material for a range of consumer goods, including toys, inflatable items, and shower curtains.

  6. Packaging: Because it is clear and easily forms into various shapes, PVC is used in packaging applications including clamshells and blister packaging.
