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 a different plastic.
nice is read your blog.Nylon is a man-made material and it is made from coal, petroleum, air, and water. In other words, it is a polymer. Nylon is not considered a natural product.

Throughout the many years that I have been collecting and buying vintage men’s magazines, titles from Pennine Magazines have always been there, but never in significant numbers - just the odd one or two copies in amongst collections of other books.
Most of you who collect, or are interested in, digest size glamour books from this period will be familiar with the titles that Pennine Magazines published in the early 1970’s, but I have yet to see a full collection of any of their titles.
The first book on the scene was, I believe, Nylon Surprise, which hit the newsstands right at the end of 1969, or possibly January 1970. Nylon Surprise was very quickly followed by Nylon Flash, Satin Flash and Smooth Satin. These four titles were the main stay of Pennine Magazines. There were four other titles that were introduced about 18 months to two years later: Exotic, Terrific, Fantastic and Dynamic. They are not that easy to date accurately, as they have very little written information in them. I have done my best to give some idea of their numbers and when they were published. Books were stated as being published monthly, with some odd numbering going on from time to time. For example, I have a couple of Nylon Surprise editions that are numbered the same but are completely different books; I also have a Satin Flash that is numbered as 12b, so who knows what was going on! It just makes it difficult 50 years later for the collector, but I don’t suppose they were really that interested in that then. I have only ever seen numbering of the main four titles into the late 30’s, which would suggest they only ran for about 3 years - as we already know the market for books like this, and of this size, was starting to change, with many titles just ceasing to exist in the 1970’s.
Pennine Magazines all followed the same format regardless of their title, which was generally that the same model would be used throughout the book. These single model editions would then be interspersed with a two-model edition; unfortunately they have no text or information about the models used.
Content is very much stockings and suspender based, with no full nudity. The suspender belts and knickers were very typical of the 1970’s - more lightweight than the 1960’s or those seen in Ben’s Books, if you know what I mean! The models seen in Pennine titles were mostly unfamiliar and a great many of the books have adverts for models to fill their pages. I suspect unknowns were cheaper than faces that were more familiar to us at that time, but that certainly is not to take away from any of the girls that graced the pages of these books.
Pennine also published specials, with these being advertised in their other titles; Super Girls, King Size Girls, Big Girls and Plus appeared, all featuring models with large or over large boobs.
Other titles from Pennine included Exciting Cinema and Sexy Laughs, which I know very little about, other than that Sexy Laughs ran to at least five volumes, which - assuming 12 books to a volume - would indicate that they were still around into the mid 70’s.
I will continue to look out for new numbers, and have digitized all the copies that I currently have, making them available for all to enjoy. New copies will be added as and when I come across them. Again, could I ask if you have more information or can help update my information, then it would be good to hear from you. Please make contact via the contact page .
