PolyEthlene Terephthalate

PGP Polymer has a range of reprocessed PET (PolyEthylene Terephthalate) flakes. PET (PolyEthylene Terephthalate) is a strong but lightweight of clear polyster. It is used to make containers for soft drink, juices, alcoholic drinks, water, edible oils, household cleaners, and other food and non-food aplication. Being a polymer, polyethlene terephthalate's molecules consist of long chains of repeating units containing the carbon, oxygen and hydrogen organic elements only.

After PET raw material is formed, it is then used for producing PET bottles starts from the raw material : ethylene and paraxylene. These two subtances derivates (ethylene glycol and terephthalic acid) get into reaction to obtain the PET resin. The resin, in the shape of small cylinders called pellets, is melted and injected into a mould to make preform. The preform, a sort of test tube shorter than what the bottle will be but with thicker walls is the blow-moulded. During the blowmoulding phase, high pressure air is blown into the preform allowing it to take the exact shape of the mould it is set into. The final product is a transparent, strong and lightweight bottle.

PET flakes can be further processed into two grades: film grade and textile grade. PET film grade is one of the most widely used plastic films in the world and is commonly extruded back into rolls of sheet which are then thermoformed into new trays for packaging. It is highly diversified in its applications from industrial, such as pressure sensitive labels and tapes, cable wrapping or insulation laminates, through packaging, graphic art, metalizing or decorative, to the high-tech application of audio, video and computer tape.

PET textile grade are produced by granulizing polyester formed in a polycondensation reaction of pure telephthalic acid and monoethylene glycol. They are manufactured to produce fibres for textile application and are supplied to the yarn-producing industry in semi-dull and super bright.
