Polymers is the group that Polyester is part of and that contains the Ester Functional Group in the main chain. Although there are many polyesters, the term "polyester" as a specific material most commonly refers as Polyethylene Terephtalate also called PET. Polyesters include naturally-occurring chemicals, such as in the Cutin of Plant Cuticles, Synthetics such as Polycarbonate and Polybutyrate. Polyesters aren't biodegradable.
Polyesters may be produced in numerous forms such as sheets and three-dimensional shapes. 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.
Woven polyester fabrics are used in consumer apparel and home furnishings such as bed sheets, bedspreads, curtains and draperies. Similarly, industrial polyesters are used in tyre reinforcements, ropes, fabrics for conveyor belts, safety belts, coated fabrics and plastic reinforcements with high. Polyester fiberfills are also used to stuff pillows, comforters and Energy Absorption cushion padding.
Polyester fabrics are claimed to have a "less natural" feel when compared to similarly-woven fabrics made from natural fibers, like cotton. However, polyester fabrics may exhibit other advantages over natural fabrics, such as improved wrinkle resistance. As a result, polyester fibers are sometimes spun together with natural fibers to produce a cloth with blended properties.
Polyesters are also used to make:
Bottles, Films, Tarapaulin, Canoes, Liquid Crystal, Displays, Holograms, Filters, Dielectric film, Insulation for Wire and Insulating Tapes..this to name a few.
Liquid crystalline polyesters are among the first industry liquid Thermosetting polyesters are used as Casting materials, and chemosetting Polyester resins are used as Fiberglass laminating resins and non-metallic auto-body fillers. Fiberglass-reinforced unsaturated polyesters find wide application in bodies of yachts and as body parts of cars.
Polyesters are also widely used as a finish on high-quality wood products such as Guitars,Pianos and vehicle and yacht interiors.
