Chemical structure of polyethylene terephthalate (PET) polyester. Effect of ethylene oxide sterilization on yield stress of amorphous PET.40, Table 5.41. PET is also known by other trade names such as Mylar, Decron, Terylene, Recron, and Lavsan. Mechanical recycling of PET materials usually consists of multiple stages such as sorting, granulation, floatation, washing, drying, extrusion, and granulation of PET. 6.12. Main elements and BE energy values can be detected in the surveys reported in Fig. Effect of electron beam irradiation on the dissipation factor retained versus dose for polyethylene terephthalate.31, Figure 5.41. Table 2.11. Terephthalate polyethylene has a high strength to weight ratio. Polyethylene terephthalate (PET) implants are composites of four tightly woven polyester strips wrapped in a sheath of loosely woven velour and act as a scaffold for fibrous tissue in-growth. Effect of gamma sterilization on haze of amorphous PET.40, Figure 5.36. It can be used in glass replacement in some applications PET is widely used in many applications in the automotive industry like engine cover, wiper arm and gear housings, head lamp retainer, and connector housings. Effect of ethylene oxide sterilization on the instrumented dart impact energy of amorphous PET.40, Figure 5.42. It has somewhat lower strength and stiffness than polyethylene terephthalate, PET, is a little softer but has higher impact strength and very similar chemical resistance. Register for freeForgot Password ? PET is in the group of thermoplastic polymers and is polyester synthesized from terephthalic acid and a diol, commonly ethylene glycol (Farah et al., 2015). It makes a good gas and fair moisture barrier, as well as a good barrier to alcohol (requires additional "barrier" treatment) and solvents. ScienceDirect ® is a registered trademark of Elsevier B.V.

Chemolysis processes for PET are mainly divided as follows: glycolysis, hydrolysis, methanolysis, and aminolysis processes [7]. As a raw material, PET is regarded as a safe, strong, lightweight, flexible and non-toxic material which can be easily recycled. Polyethylene terephthalate is commonly referred to as polyester. The recycling of PET can be conducted using various methods such as mechanical recycling and chemical recycling [6]. Polyethylene terephthalate (PET or PETE) is a general-purpose thermoplastic polymer which belongs to the, Molecular Structure of Polyethylene Terephthalate, »  View all PET commercial grades and suppliers in Omnexus Plastics Database, PET, a Material of Choice of Food Packaging Applications, Coca-Cola has Produced Recyclable PET Bottle Made Entirely from Plants, Polyethylene Use is Solar Panels and Automotive Parts, Nanoalloy® Technology Improves Impact and Chemical Resistance, Maximize the Resistance of Your Polyurethanes Over Time, Be the first to comment on "Polyethylene Terephthalate (PET): A Comprehensive Review", Your email address and name will not be published, submitting a comment or rating implies your acceptance to, Limitations of Polyethylene Terephthalate, Blends with Thermoplastics and Thermosets, How PET is made and Its Processing Conditions, It is very strong and lightweight & hence easy and efficient to transport, It is known for its good gas (oxygen, carbon dioxide) and moisture barrier properties, It exhibits excellent electrical insulating properties, PET has broad range of use temperature, from -60 to 130°C, As compared to PBT, it also has higher heat distortion temperature (HDT), It has low gas permeability, in particularly with carbon dioxide, PET is suitable for transparent applications, when quenching during processing, PET doesn’t not break or fracture. Due to its intensive production, the disposal of waste PET has been an environmental problem for many years. Polyethylene terephthalate, or PET, a strong, stiff synthetic fiber and resin and a member of the polyester family of polymers. Data for PET plastics are found in Figs. Other packaging applications include rigid cosmetic jars, microwavable containers, transparent films, etc. Methanolysis can take a crucial role of depolymerizing low quality polyester bottles. PET is spun into fibers for permanent-press fabrics, blow-molded into disposable beverage bottles, and extruded into photographic film and magnetic recording tape. 5.3931, Table 5.43. Due to its significant water and moisture resistance, it is widely used in making plastic bottles for soft drinks. It has low gas permeability, in particularly with carbon dioxide. Figure 6.14. The produced groups were used as anchor sites for covalent immobilization of heparin or coimmobilization of heparin/collagen on the PET surface and were characterized by XPS. Its crystallinity varies from amorphous to fairly high crystalline. We use cookies to help provide and enhance our service and tailor content and ads. Unless otherwise specified, all data listed is for natural or black colored materials. Polyethylene terephthalate (PET) is an aliphatic-aromatic and semicrystalline thermoplastic polyester of prime commercial and industrial importance. Introduction History of PET: PET was discovered in the mid 1940s in the US by chemists in the DuPont company who were trying to look for polymers that would be used in order to make new textile fibers. In these solvolysis reactions, PET degradation is conducted using different solvents such as water, amines, alcohol, acids, etc. Polyethylene terephthalate is a polymer that is formed by combining two monomers: modified ethylene glycol and … These PET degradation alternatives including various methanolysis and hydrolysis methods are reviewed. It is practically shatter-resistant and hence, a suitable glass-replacement in some applications, It is recyclable and transparent to microwave radiation, PET is approved as safe for contact with foods and beverages by the FDA, Health Canada, EFSA & other health agencies, Excellent resistance to alcohols, aliphatic hydrocarbons, oils, greases and diluted acids, Moderate resistance to diluted alkalis, aromatic & halogenated hydrocarbons, Lower moldability than PBT, due its slow crystallization rate, Attacked at high temperatures (>60°C) by ketones, aromatic and chlorinated hydrocarbons and diluted acids and bases, PET modified with polyolefins are often glass fiber reinforced and used in injection molded automotive and industrial applications, Blending thermosets with PET significantly improves thermal, mechanical, impact resistance and flame retardant properties. Polyethylene terephthalate has outstanding chemical resistance to organic matter and water (depending on the view and its expected application, it is … Initial Property Values for Fig. Polyethylene terephthalate Key Properties.
