Nylon 6 Rod:
Nylon 6 Rod is the other hugely popular grade that does posses some advantages over Nylon 66 Rod, notably there is a small cost advantage and also there is a size range advantage particularly in the higher end of the spectrum. Nylon 6 is also the most popular grade throughout the rest of Europe. Nylon 6 Rod is made in the two different processes, cast and extruded. Cast Nylon 6 Rod is produced by carefully heating the polymer and pouring in to moulds and then allowed to cure in special ovens to allow any trapped air bubbles to escape. This process provides a Nylon Rod that is very stable and because it is allowed to naturally form, it can produce a lower stressed product. The other manufacturing process is the extrusion method which produces a Nylon Rod that is economical and available in longer lengths than the cast method. The Nylon 6 extruded size range is similar to the Nylon 66 as the extrusion process limits the high end sizes.
