Spandex, Lycra, or elastane is a synthetic fiber known for its exceptional elasticity. It is a polyether - polyurea copolymer that was invented in 1958 by chemist Joseph Shivers at DuPont . [ 1 ] [ 2 ] [ 3 ]
An elastomer is a polymer with viscoelasticity (i.e. both viscosity and elasticity) and with weak intermolecular forces, generally low Young's modulus (E) and high failure strain compared with other materials. [1]
Solid polymeric foam for packaging under the optical microscope. A polymeric foam is a special foam, in liquid or solidified form, formed from polymers. [1]Examples include:
Elasterell (officially "elasterell-p") is an alternative to the generic term "polyester" for a specific subgroup of inherently elastic, multicomponent textile fibers. [1]The Federal Trade Commission (FTC) in November 2002 issued a final rule which establishes the name. [1]

In 2018 more than 343 million tons of plastic waste were generated, 90% of which was composed of post-consumer plastic waste (industrial, agricultural, commercial and municipal plastic waste). The rest was pre-consumer waste from resin production and manufacturing of plastic products (e.g. materials rejected due to unsuitable color, hardness ...
Elastolefin is a fiber composed of at least 95% (by weight) of macromolecules partially cross-linked, made of ethylene and at least one other olefin.When stretched to one and a half times its original length, it recovers rapidly to its original length.
ASA has lower glass transition temperature than ABS, 100 °C vs 105 °C, providing better low-temperature properties to the material. [3] ASA has high outdoor weatherability; it retains gloss, color, and mechanical properties in outdoor exposure. It has good chemical and heat resistance, high gloss, good antistatic properties, and is tough and ...
