Nylon is a generic designation for a family of synthetic polymers, more specifically Polyamides, abbreviated as (PA). Nylon is one of a large family of thermoplastic polymers. Simply, nylon is made up of long chains of repeating chemical units arranged into crystal-like formations (crystallites). Crystallites are formed by these chemical units organizing themselves in closely ordered groups. These groups are surrounded by areas of disorder (amorphous regions). These crystal-like regions give the nylon its abrasion resistance. The amorphous regions give nylon its resiliency. Our PERFECAST NYLON PERFECTEX NYLON range incorporates different grades suitable for specific industrial applications.
Nylon, by nature, lends itself to bearing materials and other friction reducing applications. Nylon has a low coefficient of friction and resists abrasion. It provides a surface able to handle repeated abuse while retaining its original shape. Nylon (PA-6) will retain its inherent physical properties after continuous service at temperatures approaching 220°F/ 104°C, whereas many grades of Nylon can continuously work at 160OC.
Polyamides are subdivided into various basic types depending upon the number of carbon atoms in the crosslinking of monomers. The most important monomeric copolymer types for technical applications are PA-6, PA-66, PA-12, PA-6-G, PA-6/12-G, PA-12-G, PA-6/10, PA-6/11 PA-4/6 and these have established themselves as the most important representatives of the polyamide materials.
