Polyester is a category of polymers that contain the esterfunctional group in their main chain. As a specific material, it most commonly refers to a type called polyethylene terephthalate PET. Polyesters include naturally occurring chemicals, such as in the cutin of plant cuticles, as well as synthetics through step growth polymerization such as polybutyrate. HOME SCIENCE Course Outline B.

The material is used extensively in clothing. Depending on the chemical structure, polyester can be a thermoplastic or thermoset. There are also polyester resins cured by hardeners however, the most common polyesters are thermoplastics. Fabrics woven or knitted from polyester thread or yarn are used extensively in apparel and home furnishings, from shirts and pants to jackets and hats, bed sheets, blankets, upholstered furniture and computer mouse mats. Industrial polyester fibers, yarns and ropes are used in car tire reinforcements, fabrics for conveyor belts, safety belts, coated fabrics and plastic reinforcements with high energy absorption. Polyester fiber is used as cushioning and insulating material in pillows, comforters and upholstery padding. Polyester fabrics are highly stain resistantin fact, the only class of dyes which can be used to alter the color of polyester fabric are what are known as disperse dyes. Polyester fibers are sometimes spun together with natural fibers to produce a cloth with blended properties. Cotton polyester blends polycotton can be strong, wrinkle and tear resistant, and reduce shrinking. Synthetic fibers in polyester also create materials with water, wind and environmental resistance compared to plant derived fibers. Disadvantages of cotton and polyester blends include being less breathable than cotton and trapping more moisture while sticking to the skin. They are also less fire resistant and can melt when ignited. Polyester blends have been renamed so as to suggest their similarity or even superiority to natural fibers for example, China silk, which is a term in the textiles industry for a 1. Polyesters are also used to make bottles, films, tarpaulin, canoes, liquid crystal displays, holograms, filters, dielectric film for capacitors, film insulation for wire and insulating tapes. Polyesters are widely used as a finish on high quality wood products such as guitars, pianos and vehicleyacht interiors. Thixotropic properties of spray applicable polyesters make them ideal for use on open grain timbers, as they can quickly fill wood grain, with a high build film thickness per coat. Cured polyesters can be sanded and polished to a high gloss, durable finish. Liquid crystalline polyesters are among the first industrially used liquid crystal polymers. They are used for their mechanical properties and heat resistance. These traits are also important in their application as an abradable seal in jet enginescitation needed. Polyesters as thermoplastics may change shape after the application of heat. While combustible at high temperatures, polyesters tend to shrink away from flames and self extinguish upon ignition. Polyester fibers have high tenacity and E modulus as well as low water absorption and minimal shrinkage in comparison with other industrial fibers. Unsaturated polyesters UPR are thermosetting resins. They are used in the liquid state as casting materials, in sheet molding compounds, as fiberglass laminating resins and in non metallic auto body fillers. They are also used as the thermoset polymer matrix in pre pregs. Fiberglass reinforced unsaturated polyesters find wide application in bodies of yachts and as body parts of cars. According to the composition of their main chain, polyesters can be Increasing the aromatic parts of polyesters increases their glass transition temperature, melting temperature, thermal stability, chemical stability. Polyesters can also be telechelicoligomers like the polycaprolactone diol PCL and the polyethylene adipate diol PEA. They are then used as prepolymers. Family Tree Maker 2012 For Mac. IndustryeditPolyester is a synthetic polymer made of purified terephthalic acid PTA or its dimethyl ester dimethyl terephthalate DMT and monoethylene glycol MEG. With 1. 8 market share of all plastic materials produced, it ranges third after polyethylene 3.

There are several reasons for the importance of polyester The relatively easy accessible raw materials PTA or DMT and MEGThe very well understood and described simple chemical process of polyester synthesis. The low toxicity level of all raw materials and side products during polyester production and processing. The possibility to produce PET in a closed loop at low emissions to the environment. The outstanding mechanical and chemical properties of polyester. The recyclability. The wide variety of intermediate and final products made of polyester. In the following table, the estimated world polyester production is shown. Main applications are textile polyester, bottle polyester resin, film polyester mainly for packaging and specialty polyesters for engineering plastics.

Raw material producereditThe raw materials PTA, DMT, and MEG are mainly produced by large chemical companies which are sometimes integrated down to the crude oil refinery where p Xylene is the base material to produce PTA and liquefied petroleum gas LPG is the base material to produce MEG. Polyester processingeditAfter the first stage of polymer production in the melt phase, the product stream divides into two different application areas which are mainly textile applications and packaging applications.
