Nylon plastic is a strong, stiff mechanical and engineering machinable thermoplastic with outstanding toughness, dimensional stability, and wear resistance.
Perfect for bearing and wear applications, nylon is frequently used to replace metal bearings and bushings, many times eliminating need for external lubrication.
Nylon has served well in replacing many metals and offers a design choice when noise reduction and long life are important.
Other benefits include a reduction in part weight, less operating
noise, and decreased wear on mating parts.
Cast nylon, also called type 6 nylon, is a versatile thermoplastic with excellent bearing and wear properties. It is more cost-effective, machinable, and dimensionally stable than its extruded counterpart. Cast nylon is often used for producing larger, thicker shapes and custom cast parts. It is favored for higher temperatures over extruded nylon due to its higher maximum operating temperature.
Cast nylon inherently has less stress versus extruded nylon. Lower moisture absorption gives cast nylon a higher dimensional stability, while the more crystalline structure of cast nylon gives it higher strength.
Extruded nylon, also called type 6/6 nylon, is an engineering thermoplastic with many similar properties to cast nylon. Like cast nylon, it is a lightweight material compared to metal and is often used to replace metal parts in bearing and wear applications.
Extruded nylon's low coefficient of friction reduces or eliminates the need for external lubrication, potentially extending service life and reducing wear of mating parts. It exhibits excellent resistance to both chemicals and moisture.
Nylon is available in a variety of specialty
formulations. Molybdenum disulphide-filled (MD) and oil-filled nylons have enhanced wear
and mechanical properties, while heat stabilized nylon will withstand higher operating temperatures.
Nylatron NSM was developed for demanding applications where larger size parts are required.
Nylon is used in many mechanical, textile, injection molding, and medical applications. Nylon in non-fibrous castable form is used almost exclusively for mechanical purposes such as gears and sprockets. In fibrous forms, Nylon has many textile applications.

Nylon is a synthetic thermoplastic linear polyamide (a large molecule whose components are bound by a particular type of bond) that was first produced in 1935 by American chemist Wallace Carothers, who was then working at the DuPont research facility in Delaware. Wallace produced what is technically known as Nylon 66 (still one of the most common variants). Demand for synthetic materials in general, and Nylon in particular, grew during World War II when natural items like silk, rubber, and latex were in significantly shorter supply.
Nylon is used for a variety of applications, including clothing, reinforcement in rubber material like car tires, for use as a rope or thread, and for many injection molded parts for vehicles and mechanical equipment. It is exceptionally strong, relatively resistant to abrasion and moisture absorptivity, long-lasting, resistant to chemicals, elastic, and easy to wash. Nylon is often used as a substitute for low-strength metals. It is the plastic of choice for components in the engine compartment of vehicles because of its strength, temperature resilience, and chemical compatibility.
Nylon can also be combined with a large variety of additives to produce different variants with significantly different material properties. Here is a look at a composite gear made of both Nylon and carbon.
Nylon is commonly referred to using the chemical designation “PA” (e.g., PA 6 or PA 6/66) and is most widely available in black, white, and its natural color (off-white or beige). Perhaps the most common variant for engineering applications is Nylon 6/6. Nylon 6/6 can be extruded (melted and forced through a die) and is also a suitable plastic for both injection molding and 3D printing. It has a high melting temperature, making it an excellent substitute for metals in high-temperature environments (e.g., under the hood of a vehicle). The material’s downside is that it has relatively low-impact strength (even when compared to other plastics; see the chart below). The following diagram shows the relative impact strength of Nylon when compared to the impact strength of other commonly used plastics such as ABS, Polystyrene (PS), or Polycarbonate (PC). Of note, the impact strength of Nylon can be improved by a process called “conditioning.” For this reason, as well as the ease with which Nylon can be combined with other materials to enhance its strength, it is important to check the material properties of the specific Nylon material you are using.
Now that we know what it is used for, let’s examine some of the key properties of Nylon (PA). Nylon is a condensation copolymer that is composed of several different monomer types in combination with one another. It can be produced in a variety of ways, typically starting with distillation from crude oil, but it can also be produced from biomass. Nylon is classified as a “thermoplastic” (as opposed to “thermoset”) material, which refers to the way the plastic responds to heat. Thermoplastic materials become liquid at their melting point - a very high 220 degrees Celsius in the case of Nylon.
One useful attribute about thermoplastics is that they can be heated to their melting point, cooled, and reheated again without significant degradation. Instead of burning, thermoplastics like Nylon liquefy, which allows them to be easily injection molded and then subsequently recycled. By contrast, thermoset plastics can only be heated once (typically during the injection molding process). The first heating causes thermoset materials to set (similar to a 2-part epoxy), resulting in a chemical change that cannot be reversed. If you tried to heat a thermoset plastic to a high temperature a second time, it would burn. This characteristic makes thermoset materials poor candidates for recycling.
Nylon is often used in gears, bushings, and plastic bearings because of its inherent low-friction properties. Nylon is not the most slippery plastic available - typically, we recommend acetal if low friction is the only consideration. However, it’s high performance in other mechanical/chemical/thermal properties make it a good choice for parts that could see a lot of wear.
Nylon is also an incredibly useful plastic for applications that do require both a plastic material as well as a high melting temperature. It is also incredibly diverse. Nylon can be adapted to a wide variety of uses because of the many different variants in production and the adjustable material properties of these variants resulting from the different materials Nylon can be combined with. At Creative Mechanisms, we have used Nylon in several applications across a range of industries. A few examples include the following:
Although Nylon was discovered and initially patented by Dupont’s Wallace Carothers, it was produced (as Nylon 6) three years later (in 1938) using a different methodology by German research chemist Paul Schlack, then working at IG Farben. In the modern era, it is manufactured by a large number of firms, each typically with their own production process, unique formula, and trade names. You can view a full list of material manufacturers here .
Common variants include Nylon 6, Nylon 6/6, Nylon 66, and Nylon 6/66. The numbers indicate the number of carbon atoms between acid and amine groups. Single digits (like “6”) indicate that the material is devised from a single monomer in combination with itself (i.e., the molecule as a whole is a homopolymer). Two digits (like “66”) indicate that the material is devised from multiple monomers in combination with each other (comonomers). The slash indicates that the material is made up of different comonomer groups in conjunction with each other (i.e., it is a copolymer).
Nylon, like other plastics, typically starts with the distillation of hydrocarbon fuels into lighter groups called “fractions,” some of which are combined with other catalysts to produce plastics (usually via polymerization or polycondensation). Nylon can also be produced from biomass. Based on the nature of biomass, it can potentially result in a more biodegradable material. The actual process for Nylon production falls into one of two methodologies. The first involves the reaction of monomers with amine (NH2) groups reacting with carboxylic acid (COOH). The second consists of the reaction of diamine (a molecule with 2 x NH2 groups) with dicarboxylic acid (a molecule with 2 x COOH groups).
Nylon can be easily melted into filaments (useful for 3D printing), fibers (useful for fabrics), films (useful for packaging), and sheet stock (useful for CNC machine manufacturing). It is also an easily injection moldable material. Natural Nylon stock is most commonly an off-white color, and it is also commonly available in white and black. That said, Nylon can be dyed into virtually any color. The material is readily available in filament form for 3D printing where it is heated, and the melted filament is manufactured into the desired 3D shape.
When our company designs prototype Nylon parts, we CNC machine them. A few years ago, our company started prototyping plastic hooks for use with bungee cords. We start with an ABS FDM prototype to confirm size/shape/aesthetics/function. Then we CNC machine the hook in Nylon to test strength. The final step is injection molding the production parts.
With injection molding, Nylon is sometimes filled with a certain percentage of glass fibers to increase its tensile strength. The percentage of glass is typically between 10% and 40%. The hooks we are injection molding are actually above 40%. The glass fibers do increase strength, but they also impact the way a part fails. With no glass fill, Nylon will bend and yield before it breaks. With the addition of the glass fibers (especially at higher percentages), the failure becomes an instantaneous brittle break with minimal bending. When Nylon has a glass fiberfill, it is referred to, for example, as 30% GF Nylon. (GF stands for “glass filled”).
Although Nylon has a high melting temperature, it does not stand up well to an open flame. It is a flammable material and burns quickly when and if it is exposed to an open flame. Flame retardants can be added to the Nylon in order to improve flammability. For example, the Nylon being used for the manifold in one of our new design projects has the highest flame rating (V-0).=
Nylon can also be negatively impacted by UV exposure, primarily from direct sunlight. Because of this, a UV stabilizer is often added to the material before it is injection molded.

Thank you very much for your valuable information on nylon. Are there any fillers which can be substitute for glass fibers?
Kasup, there are many different fillers that can be used with Nylon. Choosing the right filler would be specific to your application. However, I am aware of Nylon materials that use fillers in the form of Aramid Fibers, Glass Beads, Silicone, PTFE, Carbon Fiber, and Stainless Steel Fibers.
hi, i ask about the histogram graph. how the nylon66 has impact strength less than acrylic???
Ibrahim, that chart was taken from this site (http://www.ptsllc.com/intro/product_intro.aspx). I am not sure what data they referenced for the chart.
Acrylic is stronger and stiffer than Nylon. Impact strength is a Proxy measure of the area under the SS curve( the energy absorbed to rupture). Nylon is less strong yet more elastic. The data above tells you the acrylic is more brittle than the nylon. Basically the area under the SS curve of acrylic is smaller than that of nylon ( hence PA absorbs more energy to rupture thus has a higher impact resistance) . Also the glass transition temperature (Tg) of atactic PMMA is around 105C while the Tg of Nylon is around 50C.Expectation is acrylic is "more glassy" at room temperature than nylon
Hello.

is the material more prone to expanding due to slight heat changes?

I am currently dealing with an overseas supplier who submitted samples to me that are out of spec. His answer is the PA material can warp in transportation into different climates. Just wondering if this is true?
Darren, Nylon can absorb environmental moisture (humidity) which can cause its dimensions to fluctuate and mechanical properties like tensile strength to change.
Very usefull information! Thanks!
We have design a part with PA66 Nylon resins. The part is 0.4mm in thickness, is flexible with a very good strength (exactly what I want !!!). But when heated @85C for 2 weeks, the part loose it's flexibility and break easily. What is happening? Is there an other plastic with the same properties but better heat tolerance?
Eric, it is possible that the heating cycle you are exposing the nylon to is drying out the material. Nylon's properties are dependent on the amount of moisture in the material. Perhaps you need to do a water conditioning treatment, or select
