How is PVC made?

How is PVC made?

He is prepared from two raw materials: 57% sea salt (NaCl) and 43% petroleum; vs’is the only plastic material made up of more than 50% raw material of mineral origin. the PVC rigid is mainly used for the manufacture of profiles and tubes by extrusion.

How is PVC used?

During the recycling process, the PVC is deposited in a shredder. This allows the material to be crushed in order to transform it into flakes. These then go through a sorter to remove the metals from the polyvinyl chloride.

Is rigid PVC recyclable?

Today, two methods of valuing the Rigid PVC exist: – the recycling : the PVC is reintroduced in open loop in many applications; – energy recovery: the PVC is used as fuel.

How is a PVC window made?

the PVC is a synthetic plastic resin that is formed through the polymerization of vinyl chloride, itself made with chlorine extracted from salt and ethylene extracted from petroleum. Resin PVC in its pure state consists of a white powder that can be used to make carpentry.

What is the property of PVC?

The properties intrinsic to PVC give it a number of advantages such as its composition, with its limited content of petroleum derivatives, compared to other polymers, its very good fire resistance, its long life, its ease of maintenance and its resistance to ‘water.

What is the disadvantage of PVC?

And above all, the PVC is very affordable compared to other materials used in construction such as aluminum or wood. Be careful, this thermoplastic polymer still reveals certain limits. He doesis not biodegradable and may become toxic in the event of combustion or fire.

Is vinyl siding recyclable?

1. The vinyl and recycling. One of the reasons for the great durability of the vinyl is its recycling capacity at 100%. Indeed, the vinyl is a thermoplastic material that can be ground and remelted repeatedly to form various new products, even after the useful life of the initial product.

What are the different types of PVC?

There is also flexible PVC which has a shiny appearance and is mainly used in the creation of certain types of ceilings or floor coverings. Finally, there is PVC in the form of plasticized films which are used to make packaging.

What are the advantages of PVC?

Stable and inert, it does not release toxic elements on simple contact. – The PVC would contain lead: the European Directive had set the date of 2010 for a 50% reduction in lead stabilizers and that of 2015 for a PVC produced 100% lead-free.

What is the property of polyvinyl chloride?

PVC and their properties. Polyvinyl chloride or polyvinyl chloride is a thermoplastic polymer, generally known by the acronym PVC with the formula − (CH2 − CHCl) n. PVC is obtained by polymerization of vinyl chloride (VCM) or monochloroethylene:

What are the dangers of burning depvc?

– The release of dioxin: in the event of combustion of PVC, it has been demonstrated that in the context of a fire, the formation of dioxin is negligible. PVC does not produce more than wood.
