For ânylonâ strings, manufacturers typically use polymers comprised of amide functional groups such as aliphatic polyamides (including Nylon 6 and Nylon 66), and polymers comprised of ketone functional groups such as Zyex (AKA polyetheretherketone, or PEEK).
It is made of repeating units linked by peptide bonds (another name for amide bonds) and is frequently referred to as polyamide (PA). Nylon was the first commercially successful polymer and the first synthetic fiber to be made entirely from coal, water and air.t is made of repeating units linked by peptide bonds (another name for amide bonds) and is frequently referred to as polyamide (PA).
