Polyethylene terephthalate is a thermoplastic polymer of the polyester group. Despite its name, the polyethylene terephthalate does not contain POLYETHYLENE. Tolyethylene terephthalate is a polymer that is used everywhere around us. About 60% of the world's production of this polymer is for yarn for clothing, sails, etc. The production of bottles and packaging has a share of 30% and the rest of the world production is in the form of sheets. It can be transparent (with a light transmittance of over 89%), white (milky, opalescent) or light- impermeable (white, coloured) respectively with different types of surface: gloss, matt or embossed (structural, pyramidal).
In its standard version, polyester sheets do not have UV stabilization (protection), which means that they would turn yellow and lose their properties under outdoor conditions. It is also produced UV-stabilized based on a special assignment to the manufacturers with additives in the granulate.
Types of PETG and PET polyester sheets can be used for articles that come into contact with food products or require full recycling. Polyesters do not contain halides or cadmium. They are produced in different thicknesses and have a significantly higher degree of impact resistance than acrylic (plexiglas).
The particular and apparent difference between PETG and PET plates is that PETG does not crystallize during heat treatment as opposed to PET plates that crystallize (become white) when heat treated at over 100 °C. At the same time, there are additional features that are reflected in the printing, processing and gluing processes.
