Nylon 66 Rod:
Nylon 66 Rod is the grade that is most specified in the UK and is well suited to machining on both manual and automatic lathes. Nylon 66 Rod has an excellent size range option which starts at 4mm diameter up to a maximum size of 200mm. Because Nylon 66 Rod is manufactured by the extrusion process, there is some small element of production stress but this is probably entirely eleminated by manufacturers employing a rigorous anealing process. The majority of Nylon 66 Rod is specified as natural which is normally a light cream colour but the other popular option is black, this grade contains a black dye but can also very often contain an additive called Molybdenum disulphide which is described later.
