Polyester is a generic name referring to polymers made of repeated units of an ester molecule under the COO form.
Polyester is produced by reaction of carbonated acids (Terephthalic acids) with alcohols (dihydric alcohols) and elimination of water.
These polymeric groups of repeated ester units can form long chains of molecules very stable and strong offering an excellent resistance in many applications.
Polyester is one of the most important building block of the petrochemical industry as used in many applications as fibers, adhesives or plastics.
Polyester are produced from hydrocarbon sources such as coal, gas, oil.
Polyester is highly appreciated as textile fibers for its weather resistance, light weight and easy maintenance.
As outdoors wears, polyester fibers provide with insulation and thermosetting effects.
Because of its low costs and multiple characteristics, polyester fibers are mostly known under famous brands such as Lycra, Dacron, Terylene.
Invented by du Pont de Nemours in 1926, the most well-known polyester fibers is the nylon, used for wears and under-wears and appreciated as non allergenic.
In the industry, Polyester is used in many different forms and combined with other materials.
As fibers or resins, the polymeric structure of polyester offers good shocks absorption and corrosion resistance fitting perfectly for marine hull applications and molded parts for the automotive industry.
The polyester resins and fibers can also be mixed with other hydrocarbon compounds for quick drying resilient fibers and plastics.
Because of its mechanical resistance, light weight and flexibility, the nylon fibers are integrated in the structure of the tires for chocks and intrusion resistance.
