Nylon, you’ve probably seen it on the labels of some of the daily industrial plastic products or your tights or stockings. However, do you know where does it come from, what it is, and where and what it is often used, etc…Now, let’s talk about one of the most common engineering thermoplastic materials-Nylon.
Nylon material (or Polyamide) was the first synthetic fiber to appear in the world that was produced by the distinguished American scientist Carothers and a research team under his leadership. Carothers produced the Nylon 66 at that time, which is still one of the most common variants today. During World War II, there was a greater demand for Nylon compared to the supply of natural items such as silk, rubber, and latex.
Nylon material is an engineering thermoplastic that is easy to machine and can serve as various mechanical end parts. Nowadays, it has been widely used in various applications, including apparel, the reinforcement material of rubber-like car tires, for use as a rope or thread, and for many injections molded parts for vehicles and machinery. Since it has higher impact strength, relative abrasion resistance, and long-lasting chemical features, better elasticity, it is often used to replace low strengthen metal parts in automobile engines. In addition, Nylon is also can be used as electrical insulation. It is light and provides high tensile strength and low friction. This kind of material usually melts and doesn’t easily burn.
Typical Injection Molding Temperature
Heat Deflection Temperature ( HDT )
There are many different types of Nylon materials, some of which mainly including PA6, PA66, PA610, PA11, PA12, PA1010, PA612, PA46, PA6T, PA9T, and MXD-6 aromatic amide, etc. Among them, PA6, PA66, PA610, PA11, PA12 are the most widely used. However, let’s start with those as bellows:
Nylon 6 is a semi-crystalline polyamide developed by Paul Schlack.
Typical Properties: Tough, possessing high tensile strength, elasticity, and luster. They are also wrinkle-proof and highly wear-resistant and chemical resistant like alkalis and acids. Its glass transition temperature is 47 °C.
Application: Nylon 6 filaments are a kind of highly elastic fibers that are typically applied in high-strength industry and textiles, including industrial cords, ropes, and clothing. It usually produces more reliable final part dimensions.
Nylon 66 is another type of nylon or polyamide.
Typical properties: Highly fatigue-resistant and rigidity, better heat resistance, low friction coefficient, excellent abrasion-resistant, but has a greater degree of moisture-absorption and insufficient dimension stability.
Application: Bearing medium load, work temperature under <100-120 °C, without lubrication or less lubrication, as wear-resistant stressed transmission parts. Nylon 66 is also great for is injection molding.
It is also known as PA12 with the formula [(CH2)11C(O)NH]n. It is also a good thermoplastic with broad additive applications.
Typical properties: Tough, impact strength, tensile strength, and excellent flexibility.
Application: With those excellent mechanical properties, Nylon 12 (PA 12) has been liked by injection molders. Meanwhile, it is also becoming the one of most common materials in the additive manufacturing processes for producing functional parts and prototypes.
It is a kind of engineering resin that offers properties between those of nylon 6 and nylon 12.
Typical properties: Its toughness, rigidity, and heat- resistance are lower than nylon 66, but with lower moisture-absorption, better wear-resistant，excellent UV and chemical resistance, excellent resistance to zinc-chloride solutions.
Application: It is similar to Nylon, the perfect material for gears requiring high precision and Parts with high humidity variations in working conditions. Nylon 610 can be used for injection molding and extruded.
It is also known as PA 10/10, an unreinforced, plasticized, and heat stabilized, renewably sourced, biobased polyamide 1010 resin developed for extrusion.
Typical properties: It’s has better abrasion resistance, low density, high resistance to chemicals and weathering, results in good dimensional stability, and easy to machine. Its toughness, rigidity is lower than Nylon 66, moisture- absorption is lower than Nylon 610, a great organic alternative to PA12.
Application: It can be used as the workpiece when the Nylon 610 is under the condition of light load, appropriate temperature, humidity easily changes, etc.
Nylon (PA) material has diverse advantages that can make it an ideal mechanical material for a wide range of applications. You’ll find the key pros and cons of the material listed below.
Nylon material is characterized by four main types of polyamide nylon: nylon 66, 11, 12, and 46. Generally, those names derive from the length of their polymeric chains. There some typical applications include:
Automotive Industry – oil reservoir, cylinder head, radiator, oil & water tank, water pump impeller, wheel cover, outer panel, handle, gear, bearing, shank, outer plate, binding post, etc
Electronic Industry – Housings, plug-ins, binding post, connectors
Medical Industry – Implants, catheter shafts, and balloon tubing, etc
Music Industry – Guitar strings and pics
Daily uses – various gears, toothbrushes, including fishing line & fishnet, tennis racket strings, gears, tents, carpets, etc
Clothing – Shirts, foundation garments, lingerie, raincoats, underwear, swimwear, and cycle wear.
From the above, we understand some of the properties of nylon. Then, let’s discuss how to use Nylon materials for prototype development on CNC Machines, 3D Printers, & Injection Molding Machines. As we know, Nylon can be easily melted into sheet stock (great useful for CNC machining), filaments (great useful 3D printing), films (great useful for packaging), and fibers (useful for fabrics). It is also a perfect candidate for injection molding material.
At WayKen, we usually produce prototype nylon parts by CNC machine for the customers. In the past project experience, we once made plastic hook prototypes for use with the cords. We will help our customers to confirm the size/structure/shape/appearance/aesthetics/function from ABS FDM prototype. The hook in nylon was machined by our CNC machine to test the strength. Then, we use injection molding as the final step to produce the parts.
Natural Nylon raw materials are generally off-white, but also available in black and white. In another word, Nylon can be dyed into any color. This material is easily available in the form of filaments which can be used for 3D printing. On the 3D printers, it is heated and the melted filament is manufactured into the desire 3D shapes.
To increase its tensile strength, Nylon is sometimes filled with a percentage of glass fibers (glass usually occupies 10% and 40%) during the injection molding process. With injection molding, the hooks are over 40%. Although the glass fibers do increase strength to some degrees, they also impact the way a part fails. The Nylon usually will bend and yield before it breaks without any glass filling. With the high percentage of the glass fibers, the failure becomes an instantaneous brittle break with minimal bending. When Nylon has a glass fiberfill, it will have some special labels, for example, 30% GF Nylon (GF stands for “glass filled “).

Nylon is a strong, stiff engineering plastic with outstanding bearing and wear properties . Nylon is frequently used to replace metal bearings and bushings often eliminating the need for external lubrication. Other benefits include a reduction in part weight, less operating noise, and decreased wear on mating parts.
Length, width, thickness, and diameter tolerances vary by size, by manufacturer, brand, and grade. Custom sizes and colors available upon request. Tube is also available in standard outer diameter sizes from 5 in – 40 in, complete our Get a Quote form for more information.

Nylons are typically described according to numbers (6, 66, 11, 12, etc.) which relate to their molecular structures. Although there are many types of Nylon, the two most common available in sheet, rod, and tube are Nylon 6 and Nylon 6/6 .
Nylon 6 and Nylon 6/6 – have very similar mechanical, thermal, and electrical properties. Both are available in a variety of colors and formulations that are engineered to meet specific application requirements. For Nylon 6 chemical resistance view our chart.
Nylon 6 – is generally manufactured into sheet, rod, and tube via a liquid casting process. Casting is often the most cost effective method for producing large diameter rod, tube, and thick sheet. This process has the added advantage of allowing manufacturers to create custom near net (irregular) shapes. Near net shapes are useful in the construction of parts that would yield poorly from standard sheet, rod, or tube stock.
Nylon 6/6 – sheet, rod, and tube are usually produced by melting solid pellets of the polymer and processing them through a thermoplastic extruder. Extrusion is a fast and economical method for making small diameter rod, tube, and thin sheet. Unlike cast Nylon 6 stock shapes, extruded Nylon 6/6 sheet, rod, and tubing can be manufactured to any length, which can be an advantage for cost effectively yielding finished parts.
Nylon Grades – Nylon is available in a variety of specialty formulas. Molybdenum disulphide-filled (MOS2) and oil-filled nylons have enhanced wear properties often eliminating the need for external lubrication. Heat-stabilized nylon withstands higher operating temperatures. Nylon is available in glass-filled grades for enhanced stiffness and strength. FDA compliant grades of nylon are available for direct food contact.
Nylon with Metal Core– Nylon billets can be manufactured into many different components including gears, rollers, sprockets and augers. In power transmission applications, NYMETAL® billets combine the performance advantages of nylon and metal into one cohesive unit.
Tech Tip – Nylon has relatively high moisture absorption compared with many other thermoplastics. Nylon parts that must perform in wet environments should be designed with tolerances that factor in dimensional changes due to moisture absorption.
Values may vary according to brand name. Please ask your Curbell Plastics representative for more specific information about an individual brand.

Coyote Brown 1,000 Denier Cordura Nylon Fabric
Nylon is the name of a family of synthetic polymers that are commonly used to make a variety of different types of apparel and consumer goods. Unlike other organic or semi-synthetic fibers, nylon fibers are entirely synthetic, which means that they have no basis in organic material.

The use of this type of synthetic polymer in clothing began with a desire to find alternatives to silk and hemp for parachutes in World War II. At the time the war began, cotton was used for more than 80 percent of textile applications in the United States, and almost all other textiles were made from wool. By 1945, however, synthetic fibers like nylon constituted around 25 percent of the textile market share, and once the war ended, manufacturers sought new ways to market this new class of synthetic fabrics.

Directly after the war, there was a shortage of traditional dress materials like cotton and silk, so some individuals made dresses from repurposed nylon parachutes. Thus, the idea to use nylon in women's garments gained popularity, and the production of nylon stockings and lingerie rapidly picked up steam.

At the same time, nylon was finding ever greater popularity in a variety of other consumer and military markets. This substance had originally been developed by the DuPont Corporation in the early 1920s, and it's creation was officially announced at the 1939 World's Fair. At the time, DuPont had no intention of using nylon for scientific and industrial applications, and the main purpose of this new polymer was deemed to be for textiles.

At the time of its unveiling, nylon did not have its current name; upon recognizing this polymer's potential for use in fabrics, DuPont originally planned to market it under the name "no-run" due to its perceived ability to resist "runs" when used in fabric, which are forms of damage to tights that cause these garments to become aesthetically displeasing. However, it was soon discovered that nylon was, in fact, subject to runs, so the name was changed to "nuron." This name was also unsatisfactory, however, so it was changed to "nilon," and the "i" was replaced with a "y" to clarify pronunciation.

During the early days of nylon fabric, consumers noted a variety of issues with nylon fabric. Despite early marketing efforts that described nylon as "stronger than steel," nylon was found to be highly susceptible to runs and tears, and this fabric's lack of moisture-wicking properties also became a subject of concern. In extreme cases, nylon stockings would revert to coal and water.

Nylon would have been considered to be a failed experiment if producers of this material hadn't started mixing it with other textiles. It was found that when nylon fabric was mixed with polyester, spandex, or cotton, the desirable attributes of this fabric were retained, but many of the undesirable aspects of this fabric were eliminated. These days, most nylon garments consist of a blend of various fabrics.

This fabric remained popular throughout the 1940s and 1950s, but nylon and other synthetic textiles have experienced a steady drop in popularity since the 1970s. Over time, the novelty of nylon started to wear off, and consumers also became concerned about the environmental impact of this fabric. The main ingredient of nylon fabric is petroleum oil, and this textile is not biodegradable. As of 2008, however, around
12 percent of the world's synthetic fiber production consists of nylon fabric
.

Even though nylon fabric for consumer garments has declined in popularity, this polymer family has become increasingly popular for industrial and scientific purposes. For instance, nylon can be made into a plastic that is highly durable and versatile, and nylon resins are commonly used in hair combs, machine screws, gun parts, food packaging, toothbrushes, and hundreds of other applications.
