Type 6/6 is an extruded nylon while type 6 is a nylon made via monomer casting. In many applications, either product will function, but in general type 6/6 tends to have a slightly higher temperature capability. Cast nylon tends to be slightly more ductile than extruded 6/6 nylon, it can be produced in much larger shapes (and custom cast parts) and tends to be more cost-effective in larger cross-section shapes.
Both are cast 6 nylons with molybdenum disulfide fillers; VEKTON® 6 PALM also contains oil. VEKTON® 6 PALM is appropriate for more demanding bearing and wear applications (higher loads and lower speeds).
Tubes are cast “sufficient to finish to” on all dimensions, allowing fabricators enough excess material on OD (outside diameter), ID (inside diameter), and length to machine to the stated nominal dimensions.
Glass-reinforced materials tend to have higher residual stresses and therefore are susceptible to cracking during cutting or machining. We suggest heating these products at 120° C for 1 hour per 3/8″ of cross-section prior to cutting or drilling.
