PET (Polyethylene terephthalate)
Definition:
Polyethylene terephthalate which is commonly known as PET is a type of thermoplastics polymers resins. When PET is used in fabrics then it is also called as Polyester which is just like a clothing fabric. PET is lightweight, economical, non reactive and shatterproof that’s why it is highly valued packaging material. Despite its name it does not contain polyethylene. Polyethylene terephthalate (PET) consists of polymerized units of the ethylene terephthalate, with repeating units of C10H8O4





PET may exist both as invisible and also in semi colours.
Uses:
PET used in many different things such as
Food containers.
Beverage containers
Drinking water bottles
It is also used to cover bakery products
It is used to hold cosmetics products because it is easy to mold into desirable shape.
It is also used to store chemicals such as household cleaners, varnishes etc.
It is used thermal insulation such as Space blankets.
It is used as substrate in thin films and solar cells.
In synthetic fibres
Platic bottles
Juices bottles

Physical Properties:
It is colourless in its natural state. It is a good barrier to moisture, solvents and makes a good gas. It has impact resistance and very strong. It became white when exposed to other chemicals like chloroform and toluene. The most important property of PET is intrinsic viscosity which means it absorbs water from the surroundings and makes...

...polyester are just about as differed as the assembling methodologies focused around essential pellets or melt. Contingent upon virtue of the reused materials, polyester could be utilized today within the greater part of the polyester assembling techniques as mix with virgin polymer or progressively as 100% reused polymer. A few exemptions like BOPET-film of low thickness, exceptional provisions like optical film or yarns through FDY-turning at > 6000 m/min, microfilaments, and micro-strands are processed from virgin polyester just.
Conclusion:
From all of the above information and research we conclude that PET is very useful plastic among all of them because it is very effective and safe that’s why it is used to cover food and beverages. PET is very long lasting plastic. Most of the PET plastic is used in bottles, juice bottles and food storage containers.

Essay on Recycling of Polyethylene Terephthalate

- Recycling of Polyethylene Terephthalate In the United States, over 245 million tons of municipal solid waste (MSW) was produced by consumers in 2005. This is approximately 4.5 pounds of trash per person per day.[3] This same year, 79 million tons of waste were recycled, a dramatic increase from 15 million tons in 1980.[3] Of the total MSW in 2003,11.1% (26.7 million tons) was plastic. Although only 3.9% of plastics disposed in 2003 were recycled, PET was recovered at a rate of 25%.[4] There are six classifications of plastics, each assigned a number....   [tags: Recycle Plastic Waste Trash Garbage]

Essay on Polyethylene

- German Chemist Hans von Pechmann first synthesized Polyethylene by accident in 1898 by heating diazomethane. His colleagues characterized the waxy substance polyethylene due to the fact that they recognized that it consisted of long ethene chains. It was then first industrially synthesized by accident in 1933 by applying extremely high pressure to ethylene and benzaldehyde. Over the years, development of polyethylene has increased due to the additions of catalyst. This makes ethylene polymerization possible at lower temperatures and pressures.1 Polyethylene is a polymer that is made of a long chain of CH2 monomers bonded together....   [tags: Polymer Plastic]

Investigating Plastic Degradation due to Sunlight Essay

- All plastic types fall under a code no, known as an SPI code (as devised by The Society of the Plastics Industry), based on their chemical composition. As some plastics are more easy to recycle than others. Polyethylene Terephthalate ( PETE or PET) it is the most commonly recycled plastic. High-Density Polyethylene, or HDPE. HDPE products are very safe and they are not known to transmit any chemicals into foods or drinks. Plastic labeled with an SPI code of 3 is made with Polyvinyl Chloride, or PVC....   [tags: plastic, sunlight, polyethylene]

Polyethylene: Manufacturing Cycle and Environmental Impact Essay

- Manufacturing Cycle and Environmental Impact The most common form of polyethylene is petroleum based or olefins based; as before mentioned polyethylene compounds have a wide commercial applicability and are made from non-renewable resources (Harding, Dennis, von Blottnitz, Harrison, & S.T.L., 2007). Its manufacturing processes are regarded as energy intensive and release significant amount of CO2 and heat into the atmosphere (Broderick, 2008). Next a little more detailed description of polyethylene’s production processes will be presented, with a focus on the way the material inputs are extracted and synthesized....   [tags: Manufactutring Cycle, Environmental Impact]

Clay Loading and Dispersion Effects on the Rheological Properties of Unsaturated Polyester Nanocomposites

- Clay Loading and Dispersion Effects on the Rheological Properties of Unsaturated Polyester Nanocomposites The objective of this work is to characterize the influence of clay loading and dispersion effects on the rheological properties of unsaturated polyester composites. Toughened unsaturated polyester (UPE) composites were synthesized by the blending of delaminated clay with unsaturated polyester. Rheological behavior is shown to be strongly influenced by clay loading and the extent of clay dispersion in the polymer matrix....   [tags: essays research papers]

Polyethylene and Polyterephthalate are Outdated Essay

- Poly(ethylene terephthalate) Outdated: Is the World Ready for a New Plastic. Abstract: This paper explains the structure of polymer poly(ethylene terephthalate) also known as PET. It states the properties of the plastic as well recycling methods. My goal was to find out what makes PET the number one plastic, both in consumption as well as the most recycled. I also searched for new polymers that are being created by scientists and compare them to PET to see if there was a plastic out there that is better for the environment....   [tags: Polymer PET Plastic]

Thermo-oxidative Resistance of Cross Linked Polyethylene Essay

- 1. Introduction Thermo-oxidation is one of the most frequent and important stress that affects polymers, particularly those used as electrically insulating materials and is one of the main causes contributing to the final failure of insulators. By increasing the thermo-oxidative stability of the polymer, the life-time of the insulating system can be considerably prolonged. As an alternative to the bulk modification by additives or dispersed inorganic phases having micro or nano size, the depositions of thin films on the outer surface of the polymeric device has been proposed [1, 2] (valutare se aggiungene un altro di carattere generale)....   [tags: insulating materials, graphene, degradation]

Effect of monomer modification on the physico-chemical properties, degradation and in vitro biocompatibility of polyester bioelastomers

- A careful selection of monomers for biomaterial syntheses is essential for determining and controlling the functionality and biocompatibility of the biomaterials to be produced. Synthetic polyester elastomers based on molecules that are endogenous to the human metabolism have been designed [1]. In earlier studies, several investigators have reported elastic polyesters based on citric acid, in particular polyoctanediol citrate (POC) [2], poly(alkenylene maleate citrate) [3], poly(xylitol-co-citrate) [4] and poly(mannitol citric dicarboxylate) [5]....   [tags: Copolyesters, synthesized, Research]

Essay about Cloning

- For the last few decades, cloning was a fictitious idea that lay deep within the pages of some sci-fi novels. The very idea that cloning could one day become reality was thought to be a scientific impossibility by many experts but on one exhilarating day, what was thought to be "purely fiction" became reality. That fine day was February 22, 1997. A team from the Roslin Institute which was lead by Dr. Ian Wilmut changed the face of history forever by revealing what looked like an average sheep. That sheep was what was going to be one of the most famous if not the most famous sheep in modern day....   [tags: Biology Cloning]
