Polyamides comprise a family of thermoplastic polymers — collectively known by the generic term "nylon" — made of amides joined by peptide bonds. In addition to their artificial production by polymerizing an amino group and carboxylic (or chloride) acid group, polyamides occur naturally as fibers such as silk and wool.
Nylon has a wide range of uses and is one of the most commonly employed polymers. It is abrasion- and chemically-resistant, resilient, strong, and has a high melting point. Nylon applications which take advantage of these characteristics include:
Base matrix for fiberglass
Automotive engine components (manifolds, cowlings)
Replacements for metal power transmission components (gears, pulleys, etc.)
MIL-C-50885 - Polyamide resin curing agent
MIL-C-43062 - This document is for one type of modified butyl rubber coated cloth, in the unvulcanized state. It is to be used for the manufacture of acid and fuel resistant clothing and is vulcanized after assembly of the clothing.
MIL-M-20693 - This specification covers rigid polyamide (nylon) molding plastic to be used for general-purpose, weather-resistant, and dielectric applications.
