What Is The Difference Between Polypropylene And PVC?

Polypropylene is a neutral plastic containing only carbon and hydrogen, whereas PVC includes 30% chlorine in its principal structure.

When you burn polypropylene, it produces carbon dioxide and water only.

On the other hand, PVC emits harmful flames such as dioxin and chlorocarbons when you burn it.

Polypropylene is tolerant of heat, even under extreme conditions.

On the contrary, if PVC is heated naturally, it is insecure and decomposes during the process.

This video below shows you the difference between burning polypropylene and PVC.

How Are Polypropylene Sheets Manufactured?

You can make polypropylene by polymerizing propylene gas.

This is done with the presence of a catalyst system which is usually metallocene catalyst or Ziegler-Natta.

You can use a gas-phase or liquid-phase process to produce polypropylene sheets.

Gas-phase polymerization is more flexible, cheaper and can be used with lots of catalysts.

This video shows you the polymerization of propylene to polypropylene.

You can then use the flat die plastic extrusion process to make polypropylene sheets.

In this process, you continuously melt and move polypropylene resin in the shape of small beads into an extruder.

You can also add additives such as colors or UV inhibitors into the resin at this stage.

The resin comes into contact with a rotating screw which forces it into a heated barrel.

The melted polypropylene is forced through a flat sheet die which shapes it into the correct width and thickness.

You then wind the molten sheet through a stack of cooling rows to cool the plastic and size the thickness.

This video shows the plastic extrusion process.

Are Polypropylene Sheets Synthetic Or Natural?

Polypropylene is a synthetic resin as you can make it through the process of polymerization of the monomer propylene.
