Nylon Tube and Tubing can be made from Nylon 6 or 6/6
Nylon is one of the most popular and widely used plastic materials. From the carpet in your home to the yellow Nylon rope you have in your garage, Nylon is a tough and very wear resistant material. This self lubricating mechanical plastic material is very stiff and extremely durable. This material can be machined easily, and is a key industrial plastic resin.
Nylon 6 and Nylon 6/6 Tubing
While Nylon is a common plastic material, in the extrusion and cast grades, it is not a normal stock item for many factories. Nylon can be produced in a huge range of sizes. The cast process enables the range of sizes of a Cast Nylon Tube (Type 6) to be almost unlimited. The extrusion process is a bit more restrictive, which can produce very small sizes to larger sizes of Extruded Nylon Type 6/6 Tubing up to about 2.0″ OD. The properties of these materials are similar, and are listed here. Also, in the case of the Cast Type 6 Nylon Tube, many additives can be mixed into the casting mixture to increase many critical properties. Examples of these additives can yield: Glass Filled Nylon Tube, FDA Approved Oil Filled Cast Nylon Tubing, Cast Nylon MD Tube (molybdenum disulphide), Solid Lubricant Filled Cast Nylon Tube, and a few additional variations. These same filled items are also available in Cast Nylon Rod, Cast Nylon Sheets and Cast Nylon Plates (all made from the same Cast Nylon Type 6 resin). This casting process allows for a wide range of sizes and configurations, from round rod, cast sheet, tubular bar to near net shapes and covers on metal rollers and gears.
Why use Tubular Nylon (Nylon Tubular Bar)
There are numerous reasons to use a Nylon Tubular shaped material. 1. Vast range of sizes to fit most requirements 2. Large reduction of waste due to near net shape 3. Great reduction of machining time due to matching size to finished needs 4. Lower cost due to reduced material and reduced machining time
The difference between Nylon 6 Tubing and Nylon 6/6 Tube
The main differences are the base resin. The Nylon 6 tubing is a cast resin, and the Nylon 6/6 tube is an extrusion grade resin. Both materials are still Nylon, just a different grade of resin. The properties are also very similar, look here for specific Nylon resin properties. The other difference is that the Cast Type 6 Nylon is normally in larger sizes. This is because the cast version is poured as a liquid into molds or rigid tooling, and is done one at a time. This process, while it makes a very high quality part, is a more expensive manufacturing method, and is not cost effective in small or thin cross sections. The extrusion grade of Nylon, the Type 6/6 Nylon is heat processed in large batches. This process requires set up and large runs, and is very cost effective in these large production runs. In addition, the cross sections for the heat processed Nylon 6/6 can not be excessively large. The extruded Nylon 6/6 is therefor done sizes up to about 3″, as larger pieces are more expensive and require extra stress relieving to prevent warping.
Cast Nylon Versatility
The Cast Nylon manufacturing in the USA is very advanced. The production facilities can produce amazing and diverse sizes and shapes in the grades listed above. One of the unique versions of Cast Nylon is in the Glass Filled Nylon Tube, Glass Filled Nylon Rod and Glass Filled Nylon Sheet range. The percentage of glass fill can be custom blended to meet your specific needs, and can also contain additional fillers like MD, Oil or pigments. Many grades of Nylon are also available for very specific applications, like: bearings, sheaves, pulleys, wear plates, food processing applications, FDA approved grades, color matched for identification and many more. Other plastic materials used in these same applications include: Acetal / Delrin, PET (Polyester), PTFE and more.
