The ratio of carbon atoms is what gives each nylon type its unique property characteristics. Nylon 6/6– sheet, rod, and tube are usually produced by melting solid pellets of the polymer and processing them through a thermoplastic extruder. Crinkled nylon fibres are used for making elastic hosiery. Nylon 6/6 (INCI name Nylon-66), for example, is the polyamide synthesized from hexylenediamine and adipic acid (wherein each monomer has six methylene groups) (Figure 3).3 This polymer is an ordered, alternating co-polymer of these monomers. Nylon 6, 6, made up of monomer units hexamethylenediamine and adipic acid is the most common variant of this synthetic fibre. The two monomers can both be made from cyclohexane. Nylon 6, Nylon 6/6 and Nylon 6/12 – What is the best Nylon rod or sheet to use Nylon® Rod and Sheet (Polyamide) Grades available The Nylon® Family of plastics are all very tough, strong, machine well, and have excellent wear properties.
