Type of polymer mainly used for beverage containers (for their resistance to pressure and temperature) and textiles (porllar). It is abbreviated as PET ( Polyethylene Terephthalate ).

POLYETHYLENE TEREFTALATO called vulgarly PET ( POLYETHYLENE TEREPHTALATE ) is a polymer, perhaps the most common, used in the packaging and textile industry. It is widely used in packaging because of its high degree of crystallinity. It is processed like any thermoplastic, heating it and then subjecting it to an extrusion, injection, blowing or THERMOCONFORMATION process. When cooled quickly there is an increase in the transparency of the material, as a result of the crystals not fully developing, not producing the effect of SCATTERING, so that the glass does not interfere with the wavelength of visible light and there is almost no refraction or reflection.
