WebDec 2, 2016 · The outstanding mechanical and chemical properties of polyester; The recyclability; The wide variety of intermediate and final products made of polyester. As fibers, polyester is a term often defined as “long-chain polymers chemically composed of at least 85 percent by weight of an ester and a dihydric alcohol and a terephthalic acid”. WebPolyester thermoplastics are very hardy and versatile materials that are suitable for a wide variety of applications. In general, polyesters exhibit a good balance of strength, stiffness, and toughness, as well as excellent chemical resistance and good dielectric properties. Tensile strength can vary from 7,000 to 23,000 psi.
