Abstract

This specification covers the requirements of rigid plastic polyamide (nylon) molded and cast parts, rods, tubing, bushing stock, tubular bar, and flats for mechanical and electrical applications. <br>The polyamide rods, tubes, flats, molded and cast parts covered by this specification shall be furnished in the following composition as specified (see <a>6.2</a>). <br>Polyhexamethylene adipamide, (nylon 6/6). <br>Polycaprolactam, (nylon 6). <br>Monomer cast, (nylon 6). <br>Polyhexamethylene sebacamide, (nylon 6/10), low moisture absorption polyamide. <br>Polyhexamethylene sebacamide, (nylon 6/10) shall also be classified as electrical grade when control of its electrical properties is required (see <a>3.5.1</a> and <a>6.2</a>). <br>The polyamide specified in <a>1.2</a> shall be furnished filled or unfilled as follows and as specified by the procuring activity (see <a>6.2</a>). <br>Natural, with or without fillers. <br>Weather resistant. <br>Wear resistant. <br>Heat stabilized. <b><u>Intended Use:</u></b> The polyamides specified herein show a unique combination of general properties including strength, stiffness, toughness, resilience, abrasion and wear resistance, low surface friction, a nonabrasive surface, plus high heat resistance, good chemical resistance, and excellent dielectric properties. For critical applications, only the specific nylon which is known to meet the requirements of the intended application should be specified. The low moisture absorption material, nylon 6/10, shall be considered when the moisture resistance of the other nylons is inadequate. <br>
