Polyethylene terephthalate is not biodegradable (which is good and bad depending on your perspective and its intended use). PET is unique in that it is virtually shatterproof, has an extremely high strength to weight ratio and does not react to food and water. Polyethylene terephthalate (PETE or PET) is the most commonly used thermoplastic polymer in the world and is better known in the textile industry by the trade name “polyester.” It is a naturally transparent and semi-crystalline plastic widely used as a fiber for clothing, as an effective moisture barrier with wide applicability in bottling and packaging (known in these cases as PET or “PET resin”), and as an engineering plastic when it is combined with other materials like glass fiber or carbon nanotubes to significantly increase the material’s strength. It has good gas barrier properties and good chemical resistance except to alkalis (which hydrolyse it). Polyethylene Terephthalate commonly known as PET or PETE is the mostly used polymer in the world. Polyethylene terephthalate: micronized PET from ‘PET Reciclagem’ industry, located at Campina Grande – PB, Brazil [Figure 2]; Figure 2 – Micronized PET. PET does not react with water or food which is one of the reasons it is used for consumable packaging. It is a naturally colorless, semi-crystalline material. It will not biologically degrade even when in direct contact with food and beverages. PET was first polymerized in the 1940s by DuPont chemists looking to develop polymer materials for use as textile fibers. Polyethylene Terephthalate Properties. Polyethylene terephthalate is virtually shatterproof (it won’t break like glass packaging). It will not biologically degrade even when in direct contact with food and beverages. Degradation and Recyclability of Poly (Ethylene Terephthalate) 77 Polyethylene terephthalate (PET) is a semi crystalline polymer possessing excellent chemical resistance, melt mobility and spinnability [2-4]. Polyethylene terephthalate is highly transparent. 74 - 91 °C (165 - 195 °F) *** Heat Deflection Temperature (HDT) 70 °C (158 °F) at 0.46 MPa (66 PSI) ** Tensile Strength. Instead of burning, thermoplastics like polypropylene liquefy, which allows them to be easily, and then subsequently recycled. Polyester for fabrics is strong, flexible, and when combined with materials like cotton can reduce wrinkling, shrinking, and makes the fabric more resistant to tears. Similar to glass it is hygienic and generally resistant to attack by bacteria and other microorganisms. Polyethylene terephthalate has high strength to weight ratio. Its crystallinity varies from amorphous to fairly high crystalline; it can be highly transparent and colourless but thicker sections are usually opaque and off-white. PET is also known as polyethylene terephthalate. Some of the most significant properties of Polyethylene terephthalate (PETE or PET) are: Polyethylene terephthalate is generally “thermoplastic” (as opposed to “thermoset”) material which has to do with the way the plastic responds to heat. According to PETresin.org, “life cycle studies of PET have consistently shown it to be a highly sustainable material with a positive. Some of its most important characteristics include its resistance to water, its high strength to weight ratio, the fact that it is virtually shatterproof (it won’t break like glass packaging), and its wide availability as an economic and recyclable plastic (resin identification code “1”). PET is a clear, strong, and lightweight plastic that is widely used for packaging foods and beverages, especially convenience-sized soft drinks, juices and water. In natural state, PET is a … The global polyethylene terephthalate market was worth $ 43.81 billion in 2019.
