Nylon® Rod and Sheet (Polyamide) Grades available

The Nylon® Family of plastics are all very tough, strong, machine well, and have excellent wear properties. Nylon is a very popular plastic material, and is found in numerous applications. One of the largest usages is the production of household carpeting because of the excellent wear resistance. Nylon replaces materials such as UHMW, PET, Acetal Copolymer – Acetal Homopolymer, and ABS. It will outwear most plastics and is self lubricating.

The wide variety of types and colors is one of the largest in the plastic industry.

Nylon® Type 6/6 Rod, Sheet and PlateCommon uses for Nylon Plastic materials

The extruded Nylon 6/6 (Nylon Rod, Sheets and Tubes) material (aka: Polyhexamethylene Adiptimide) is available as Natural (tan – straw), Black, Glass filled (medium tan) and a molybdenum disulphide filled which is very dark gray. The most common size range for the extruded Nylon 6/6 is .125″ – 4.0″ diameter rod, and .125″ – 4.0″ thick sheet. The thicker materials should be cast due to cost and stress issues. For addition details on the Nylon Rod and Sheet 6/6 – see the data sheet.

Nylon Type 6 Cast Polycaprolactam

Large Cast Nylon Type 6 Rod

Cast Nylon Type 6 Rod – 26″ OD X 8.0″ Thick

The cast Nylon type 6 has almost limitless possibilities. Many colors are available in Cast Nylon, the natural color, black, blue, dark gray (normally molybdenum disulphide filled again), green and many more. Sometimes the color is determined by the additive (oil filled) or by industry. Because of its relative ease of manufacture, many companies prefer to get their Nylon in a special color to help ‘brand’ their parts.

Cast Type 6 Polyamide can be made in Nylon rod from about 1.25″ diameter to almost any size. Nylon sheet normally starts at about .75″ thickness, and once again, can be made to almost any thickness. In addition to standard rod and plate, other sizes and shapes can be cast from Nylon Type 6 – ie. discs, tubes, near net shapes, large profiles, etc. The only limitations are how much money you have, and the size of the truck to get it to you! We have had cast very large blocks (11″ X 11″ X 48″ solid), sheaves up to 66″ OD, large tubes 36″OD X 12″ ID X 14″ long, and many more massive Nylon Cast parts.

Nylon 6/12 -Low Moisture Absorption

The claim to fame for the Nylon Type 6/12 is the low moisture absorption of the material. It is more stable that the type 6 or 6/6, and with the lower water absorption, this resin can handle a wider range of environments. Our manufacturer can run this as an Extruded Nylon Rod item or as a Cast Nylon Rod item. This opens the door to a wide range of sizes and shapes. This material exhibits most of the same properties of the Nylon 6/6 and Cast Type 6, with some slight improvements in key properties.

Filled Grades of Nylon

Because of the processing of Cast Nylon, many additives can be mixed into the material. The most common are: glass filled, oil filled, Kevlar fiber filled (Hydlar Z) and the molybdenum disulphide (M0S2). In addition, other fills and colorants (pigments) can be added to assist in manufacture or processing.

Common specifications for Nylon are: L-P-410, ASTM D-4066, L-P-395C, Mil-M-20693B Comp A, Ty I, IA, II and III, Mil-M-20693B Comp B, Ty 4, Mil-P-17091B Type 1, and Mil-P-46060, PA0613, ASTM D-5989 S-PA0511, and more.

What is the difference between Nylon 6 and 6/6?

The reason for the number difference in Nylon 6 and Nylon 6/6 is due to their differences in chemical structure. Nylon 6 is made from one monomer which has 6 carbon atoms, comprised of caprolactam. The Nylon 6/6 is made from 2 monomers, each one having 6 carbon atoms of hexamethylenediamine and adipic acid, therefor the Nylon 6/6 name.

What is the structure of nylon?

Nylon is a generic designation for a family of synthetic polymers, based on aliphatic or semi- aromatic polyamides. Nylon is a thermoplastic material that can be melt-processed into fibers, films, sheets or shapes. The Nylon 6/6 is based on having 6 carbon atoms of hexamethylenediamine and 6 carbon atoms of adipic acid, therefor the Nylon 66 name.

Is Nylon and plastic the same?

The chemical name for Nylon® is PolyOxyMethylene, and it is one of the common building blocks in the Plastic family.

What is Nylon used for in engineering?

Nylon® is exceptionally strong, relatively resistant to abrasions and moisture absorption, it is long lasting, and resistant to chemicals. Nylon® is often used as a substitute for low strength metals. Perhaps the most common variant for mechanical and engineering applications is Nylon 6/6.

What is the difference between Nylon and plastic?

While Nylon® is a Plastic, not all plastics are Nylon®. Nylon® is a brand name for Polyamide produced by Dupont. The chemical name for Nylon® is PolyOxyMethylene, and it is one of the common building blocks in the Plastic family. Nylon® is a common material choosen for the excellent wear resistance and abrasion resistance. Nylon® is also produced into a durable fabric and rope.
