We could go through the super scientific jargon of how PVC is made, but this isn't the type of science class where your eyes glaze over and you start daydreaming about lunch so we'll try to keep it fun.

Basically, manufacturing PVC happens in three stages.

First, we combine chlorine (from sea salt) and ethylene (from natural gas or oils) to form ethylene dichloride. Second, we heat the s*** out of that compound in an environment with no oxygen.

This heating is called pyrolysis and it forms the vinyl chloride monomer.

Poly means many, so we essentially smush a bunch of the vinyl chloride monomers together with a process called polymerization to form a polyvinyl chloride polymer (PVC)

PVC possesses unique properties that make it suitable for many uses.

The properties of PVC include:

High density: The density of PVC is 1.38 g/cm3.

Low cost: Economically friendly and affordable.

Good durability: PVC can last up to 40 years.

High strength: High tensile strength (2.6 N/mm2) meaning it takes a lot of force to stretch it out and break it.

Excellent electric insulator: PVC doesn't conduct electricity, making it great for electrical insulation.

Fire-retardant: When PVC catches fire, it slowly extinguishes the fire because it contains chlorine and low oxygen content which combined, isn't good for fire.

Now, let's explore its benefits.
