Polyamide

The Uses of Polyamide

Polyamide (cas# 63428-84-2) is synthetic polymer of a type made by the linkage of an amino group of one molecule and a carboxylic acid group of another, including many synthetic fibers such as nylon. A polyamide is a macromolecule with repeating units linked by amide bonds.

Definition

A synthetic polymer in which the monomers are linked by the group –NH–CO–. Nylon is an example of a polyamide.

Definition

polyamide: A type of condensationpolymer produced by the interactionof an amino group of one moleculeand a carboxylic acid group of anothermolecule to give a protein-likestructure. The polyamide chains arelinked together by hydrogen bonding.

Industrial uses

Polyamide may be in linear form, known asnylon, or in aromatic form. Neither of these isof much value as a dielectric, but nylons,because of their toughness and resistance tosolvents, are used to form coatings to protectinsulation. The aromatic form can also makeyarns, but it is most often used in impregnatedboard from which it gives low-voltage insulationcapable of being used continuously at temperaturesof 150°C, or even higher.
