PVC (Polyvinyl chloride) is extracted from the polymerization of the vinyl chloride monomer. We can classify PVC into two large groups: rigid PVC and flexible PVC.

Rigid: used for the construction of pipes, pipes, containers, tool accessories, parts, blinds, windows, etc.
Flexible: Corrugated tube, traffic signals like cones. irrigation hoses, curtains for refrigerators, footwear, medicina, etc.

This material begins to soften at 80 ° C and to get rid at 140 ° C. Thanks to these and other properties, PVC is a recyclable material.

Among the main features of PVC we find:

• Different degree of hardness.
• Waterproof.
• It does not corrode.
• It is modelable if subjected to high temperatures.
• Good electrical insulation.
It is a very materialessential
• Stable and inert.
• Good mechanical resistance and impact.
• High resistance to abrasion.
• Resistant and lightweight
• Good thermal insulation
• It is odorless, tasteless and innocuous.
