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.

Nylon or nylon is a polymer of artificial origin that belongs to the group of polyamides, based on a composition of diamine and diacid chloride.
According to the amount of carbon atoms in the chains of the amine and chloride, it is indicated behind the name, for example, the most common nylon 6.6.

Nylon as it is a very elastic and resistant material is ideal for the textile industry, mainly used foror in the manufacture of stockings in the USA.
Its application was extended until today, where not only do we find nylon in the textile application, but its applications have varied, being able to find this material in utensils, and machinery.
