Nylon

Rare card · No. 54064

Nylon is a family of synthetic polymers characterized by amide linkages, typically connecting aliphatic or semi-aromatic groups. Nylons are generally brownish in color and can possess a soft texture, with some varieties exhibiting a silk-like appearance. As thermoplastics, nylons can be melt-processed into fibers, films, and diverse shapes. The properties of nylons are often modified by blending with a variety of additives. Numerous types of nylon are available. One family, designated nylon-XY, is derived from diamines and dicarboxylic acids of carbon chain lengths X and Y, respectively. An important example is nylon-6,6 ((−C(O)(CH2)4C(O)−NH(CH2)6NH−)n). Another family, designated nylon-Z, is derived from aminocarboxylic acids with carbon chain length Z. An example is nylon-[6]. Nylon polymers have extensive commercial applications, including uses in textiles and fibers (such as apparel, flooring and rubber reinforcement), molded components for automotive and electrical equipment, and films...
