How is PVC formed?

PVC is produced by polymerization of the vinyl chloride monomer. PVC comes in two basic forms: Rigid (sometimes abbreviated as RPVC) and flexible. It is the world’s third-most widely produced synthetic plastic polymer, after PE and PP. About 40 million tons are produced per year.

Is PVC made from petroleum?

Like all plastic materials, PVC/vinyl results from a series of processing steps that convert hydrocarbon-based raw materials (petroleum, natural gas or coal) into unique synthetic products called polymers. The other half of the vinyl polymer is based on the natural element chlorine. Chlorine gives vinyl two advantages.

What chemicals are used in PVC pipe?

The most widely prevalent type, Suspension grade PVC is made by polymerizing droplets of Vinyl Chloride monomer suspended in water….Primary Plasticisers:

Plasticiser Name	Plasticising Efficiency
Di Butyl Phthalate (DBP)	1.05
Di Octyl Phthalate (DOP)	1.0
Di Iso Octyl Phthalate (DIOP)	1.0
Di Nonyl Phthalate (DNP)	0.98

What is PVC found in?

Over the past few decades, Polyvinyl Chloride (PVC) plastic, commonly known as “vinyl,” has become one of the most widely-used types of plastics. We find it all around us: in packaging, home furnishings, children’s toys, automobile parts, building materials, hospital supplies, and hundreds of other products.

Is PVC a polymer of ethylene?

Poly(chloroethene), usually known as polyvinyl chloride or just PVC, is the most versatile plastic and, after poly(ethene), the most widely used….Annual production of poly(chloroethene) (polyvinyl chloride)

World	38.5 million tonnes1, 2, 3
US	6.9 million tonnes1
Europe	6.7 million tonnes1

What is PVC compounding?

PVC compound is rigid at room temperature, which can make it difficult to process. Plasticizers, which are typically liquid chemical compounds, are added to PVC resin to make it flexible. The more plasticizer added to a compound, the softer and more flexible the PVC becomes.
