POLYMERS
EXAMPLES
Polyvinylchloride.
Also known as PVC and with the general formula (C2H3Cl)n, it is obtained from the polymerization of vinyl chloride units. It is the most versatile plastic derivative known and is used for all types of packaging, footwear, coatings, hoses and even pipes.
Polystyrene.
Known as PS, it is obtained from styrene monomers, and can obtain very different results: more or less transparent, more or less brittle, or even very dense and impermeable variants.
Polymethyl methacrylate
Abbreviated with the initials PMMA, it is a typical engineering plastic, and it is one of the most competitive in terms of its industrial applications, since it is extremely transparent and resistant.
Polypropylene
Referred to in acronyms as PP, it is a thermoplastic polymer, partially crystalline and made from propylene or propene. It is used in food packaging, fabrics, laboratory equipment and films or transparent films to cover objects.
Polyurethane.
These polymers are obtained by combining hydroxyl bases and diisocyanates, and can be thermoplastic or thermosetting. They are frequently used in the footwear industry, paint, synthetic textile fibers, packaging, preservatives or machine and vehicle components.
Polymers are macromolecules made up of one or several chemical units (known as monomers) that are repeated throughout the entire chain.

Elastomeric polymers. They deform when the temperature increases, but they recover their original shape.
Thermosetting polymers. When they rise, their temperature they break down chemically. They do not deform, that is, the material does not flow.
thermoplastic polymers. When the temperature is raised, they melt and go to the liquid state, but when they cool down, they go back to the solid state.
