The Differences Between Nylon 6, Nylon 6/6, and Nylon MDS

When it comes to producing nonmetallic stamped components, manufacturers have several material options to choose from. Nylon is often a popular choice due to its versatility and various other beneficial properties. Because nylon is available in several product variations, it is well-suited for use in a wide range of industries and applications, including plumbing, automotive, household appliances, machinery components, and many more. Here, we’ll discuss the primary differences between Nylon 6, Nylon 6/6, and Nylon MDS to help you decide which option is best for your needs.

The differences between Nylon 6, Nylon 6/6, and Nylon MDS

What is Nylon 6?

Nylon 6 features a slightly lower continuous service temperature rating than Nylon 6/6 but can withstand higher speeds and loads when used in bearing applications. This material has all of the primary properties of any nylon polymer, including toughness, stiffness, good insulation characteristics, and excellent mechanical dampening.

Nylon 6 is often found in fabrics but is also a suitable replacement for steel, aluminum, brass, and other metals. Its high strength combined with its other desirable properties make it a great choice for applications such as:

  • Spacers
  • Washers
  • Gears
  • Plumbing parts
  • Bearings
  • Insulators
  • Forming dies
  • And much more

What is Nylon 6/6?

Nylon 6/6 is similar to Nylon 6 but features a few key distinguishing features:

  • Chemical resistance. Compared to Nylon 6, Nylon 6/6 is more resistant to acids, making it a better option for applications exposed to harsh chemicals.
  • Higher service temperature range. Continuous service temperature range refers to the highest temperature a material can withstand before permanent degradation occurs with prolonged exposure. While Nylon 6 has a continuous service temperature range of 200°F, Nylon 6/6’s continuous service temperature range is 210°F.

These features make Nylon 6/6 suitable for applications such as steering parts, chemical components, electrical components, plumbing parts, and more.

What is Nylon MDS?

Nylon MDS is a variation of Nylon 6/6 made with fine MDS particles. The addition of MDS enhances the load-bearing capacity of the material without sacrificing its impact resistance. MDS-filled nylon also has self-lubrication qualities comparable to PTFE, resulting in exceptionally high service life and resistance to wear.

In addition to its cost-effectiveness, Nylon MDS features superior durability and toughness, making it a great material choice for components exposed to high mechanical stresses. As the strongest and hardest form of nylon, it is ideal for applications such as washers for machinery components, parts that are in constant motion, boating and marine parts, kitchen appliances, food-grade applications, bearings, gears, and more.

How to Select the Correct Type of Nylon for Your Application

When choosing between Nylon 6, Nylon 6/6, or Nylon MDS, you must consider your application’s specific requirements for processing, mechanical properties, and aesthetic appearance:

  • Nylon 6. Nylon 6 is ideal for applications requiring a lightweight material with high stress and impact resistance. Due to its lustrous finish, it has a more attractive appearance than Nylon 6/6. However, this material is not ideal for applications exposed to high-temperature water, as it has a lower heat deflection and higher water absorption rate. For these instances, Nylon 6/6 would be the superior choice.
  • Nylon 6/6. Nylon 6/6 is the best choice for applications requiring a high-performance engineering plastic capable of withstanding higher temperatures. It also offers good stiffness, tensile strength, and flexural modulus, making it suitable for repeated long-term use.
  • Nylon MDS. Finely divided particles of MDS impart extra lubricity to this type of Nylon, allowing it to function with little to no lubrication. This makes it ideal for applications where external lubrication is contaminating, difficult to maintain, or impractical. The extra lubricity also enhances component lifespan, making Nylon MDS a cost-effective option.

Trends in Reshoring

As a family business, we place a special emphasis on providing clients with fully in-house solutions. Since 1927, New Process Fibre has served American markets with unmatched quality and cost advantages facilitated by cutting-edge tooling equipment, thorough industry knowledge, and razor-sharp quality controls.

Today, U.S. reshoring efforts have sparked massive demand for non-metallic parts stamping services, as overseas enterprises bring entire operations back home. It’s become a major test of a company’s organizational and parts management efficiencies, supplier relationships, and overall agility. We’re helping them overcome these challenges by mending broken supply chain links with American-made non-metallic stamped parts from our centrally located East Coast headquarters.

Latest Trends in U.S. Reshoring

Trends in Reshoring

What is reshoring, and what effect will it have on domestic manufacturing?

Reshoring is essentially the opposite of offshoring — when companies largely expatriated in pursuit of lower operating costs. Now, non-domestic overseas operations are facing counter-pressure to repatriate to their country of origin.

Driving these trends is a critical mass of corporate and government bodies focusing on the risks posed by offshoring, including supply chain breakdowns and the nationwide threat of disease. Overseas manufacturers are on the front lines of these and other challenges, prompting industry leaders to take a closer look at the benefits of reshoring.

An overwhelming 92% of CEOs surveyed in the Kearney 2021 Reshoring Index have expressed favorable opinions of reshoring, while 79% of U.S. executives running operations in China have either already begun reshoring operations or plan to within the next three years.

To facilitate these massive readjustments, manufacturers are turning to Advanced Planning and Scheduling (APS) software to maintain a broad view of operational needs. When integrated with Material Requirements Planning (MRP) and Enterprise Resource Planning (ERP) software, APS helps reshoring planners maintain agility while accommodating new priorities, inventory movement, and production schedules.

The result is greater scheduling flexibility and enhanced operational efficiency and accuracy. APS and ERP/MRP integrations also help industries meet consumer demand for quick deliveries and higher product assortments without succumbing to downward cost pressures.

Benefits of Reshoring and American-Made Manufacturing

The benefits of reshoring have been known for a long time, but modern geopolitical pressures might be precipitating a lasting change toward robust domestic manufacturing practices. Companies and their home countries all stand to gain from the benefits of reshoring, such as:

  • Improved Product Quality: Reshoring gives manufacturers renewed control over their production process. Because it invokes stricter regulatory standards, manufacturers must also produce higher-quality products.
  • Competitive Advantages: When available, consumers overwhelmingly prefer products made in America. A study from Perception Research Services recently confirmed that consumers gravitate to products with “Made Locally” labels, giving fully reshored companies an edge in their domestic market(s).
  • Lower Risk: Domestic production simplifies and shortens supply chains. It also makes many shipping and customs steps obsolete, and companies achieve more direct involvement in each stage of production.
  • Time Zone Alignment: Reshoring puts geographically dispersed organizations back into alignment, making it easier to coordinate production and business functions. By reducing time zone coordination issues, collaboration improves and manufacturers experience fewer disruptions.

When Nylon Washers Are Your Best Choice

Nylon washers are one of the most frequently used types of hardware for industrial design purposes. They’re critical components of threaded fasteners and make a highly cost-effective alternative to metal washers. It’s because nylon is made of a synthetic polymer, called polyamide, that’s much more affordable and easy to fabricate. We’ll explain the benefits of nylon, what nylon washers are used for, and how to select exactly the right nylon washer for your application.

Features of Nylon Washers

Nylon Washers

Unlike metal alternatives, nylon washers are adaptable to a wider range of applications. They’re essentially small pieces of hardware, usually of a flat ring shape, though they can be made in virtually any shape and color. In addition to flat ring washers, there are also square, half-moon, quarter-moon, and many other shapes. Nylon washers are most often used to seal components, separate hardware, and distribute the load forces exerted by threaded fasteners.

New Process Fibre is fully equipped to design and fabricate any type of nylon washer according to the exact specifications of our clients. Depending on the nylon washer’s purpose, our nylon fabrication and stamping specialists can provide fast quotes for washers of any size, shape, thickness, and material considerations.

Benefits of Nylon Washers

Due to nylon’s unique balance of qualities, nylon washers are a highly effective and versatile choice for numerous industries. The main benefits of nylon include the following:

  • Lightweight
  • Durability
  • Chemical, rust and mold resistance
  • Absorptive properties for both vibration and noise
  • Compressible into effective mechanical seals
  • Low surface friction, facilitating easy movement between materials (which slows deterioration)
  • Electrical and thermal Insulation
  • Cost-effectiveness

Because nylon washers are lighter than metal, they’re also cheaper to ship and can boost the fuel economy of automobiles, aircraft, and other vehicles requiring high quantities of washers.

Nylon Washers Considerations

What are nylon washers used for? With nylon’s extensive material benefits, virtually every industry relies on nylon washers. Generally, they’re frequently used wherever a design requires mechanical spacing or load distribution between hardware when metal is ineffective due to corrosion, weight, or other limitations. There are numerous factors to consider when deciding when to use nylon washers in your project.

Dimensions are a primary consideration, including thickness. This raises the question of function: will your nylon insulate or seal components, space hardware apart, or distribute forces exerted by fasteners? For example, thicker nylon washers are more durable and absorptive than thinner alternatives, but they take up more space and may be less compressible.

Shape is another consideration. Options besides flat rings can be useful in uniquely shaped recesses or when only one-half of a fastener is accessible. In the latter case, moon-shaped nylon washers are appropriate. The right type of nylon is also important, and there are several types of nylon with unique mechanical, chemical, and other properties.

Certain polymers, such as Nylon 6, have higher impact resistance and load-bearing capacity than standard nylon. Nylon 6/6, a more crystalline type of Nylon 6, is even stronger, with greater thermal insulation and less water absorption.

Our nylon fabrication experts can work closely with you to select the right combination of form factors and material considerations to most effectively achieve your design requirements.

Plastic Extrusion Guide

Plastic extrusion is a highly customizable fabrication process that uses thermoplastic resins and a pre-shaped die to create components at high volumes. This manufacturing method can utilize different extrusion techniques based on the needs of the end application.


Polyethylene plastics are some of the most commonly used plastics on the market today. They are found in products you use every day, from water bottles to sandwich bags to garbage cans. Polyethylene plastics can be further broken down into High-Density Plastics (HDPE) or Low-Density Plastics (LDPE).

Polyethylene plastic is created through the polymerization of petroleum. Although HDPE and LDPE are both polyethylene plastics, they have visible differences. This is due to the differences in the manufacturing process. LDPE has an amorphous structure that isn’t organized, while HDPE has either a partially or completely crystalline structure, making it stronger and more durable.

High-Density vs. Low-Density Polyethylene

HDPE WashersHigh-density polyethylene is a petroleum product. This polymer is melted into liquid form for easy molding and shaping. This allows manufacturers to create custom-shaped, durable containers. During manufacturing, HDPE experiences very little polymer branching, keeping the molecular structure very tight. The resulting material is strong and more rigid with the ability to retain its shape under pressure.

HDPE is ideal for projects that require custom printing or coloring. Since it’s both easy to manufacture and incredibly strong, it’s a preferred material for packaging. HDPE can also be made food-safe and it is capable of withstanding caustic chemicals.

LDPE is a lighter and more flexible plastic. LDPE polymer chains experience a considerable amount of branching and spreading. Since the chains are separated or scattered, the plastic has far less structure. The resulting plastic is lighter and more flexible. Its softness, however, means it is prone to damage.

Similarities Between HDPE vs. LDPE

There are numerous similarities between the two polyethylene plastics. Both plastics have a low material weight, are highly recyclable and have a high impact strength, and can be resistant to water vapor, weathering, and even chemicals. The tensile strength of both plastics ranges from 0.02 to 0.40 N/mm2 and are cost-effective to manufacture. Polyethylene is naturally inert, which provides both HDPE and LDPE with excellent mechanical and electrical properties.

Differences between HDPE & LDPE

The different production methods of the two substrates give them very distinct properties. These include:

  • Physical Characteristics: HDPE is much sturdier than LDPE. LDPE has a lower melting point and the products are usually more transparent than HDPE products. LDPE is slightly abrasion-resistant but is the more fragile of the two plastics. HDPE is more rigid. This durability makes it more resistant to chemicals. It has a higher melting point, which means it can withstand greater temperatures. Unlike LDPE, it’s much less transparent. HDPE is fully abrasion-resistant.
  • Recyclability: Both plastics can be recycled, but have different recycling requirements. LDPE is a recycling number 4 product and is more difficult to recycle due to its softness, increasing the risk of binding or clogging recycling machinery. HDPE is a recycling number 2 product and is easier to process through the recycling equipment.
  • Production Methods: HDPE is manufactured by heating petroleum to an extreme temperature. This releases ethylene gas monomers, which combine to form the polymer chains. LDPE is created by compressing the monomer ethylene gas within a tubular reactor, or autoclave, to facilitate linking monomers, creating the polymer chain.

Applications of HDPE vs. LDPE

LDPE washersHDPE and LDPE are often used in the same industries, but for different purposes. These industries include:

  • Hydraulics and pneumatics
  • Automotive
  • Packaging
  • Pipe and Piping
  • Electrical

HDPE plastics are used in applications such as:

  • Food processing
  • Chemical and petroleum manufacturing
  • Pharmaceutical processing

LDPE plastics are used for applications such as:

  • Food processing
  • Paper processing
  • In the marine market

HDPE Solutions from New Process Fibre

New Process Fibre specializes in complete HDPE stamping and die-cutting services. We are an ISO 9001:2015-certified manufacturer that provides custom thicknesses, widths, and colors to meet your project’s requirements.

Contact us for further information on our HDPE solutions.

Types of Thermoplastic Extrusion

Plastic extrusion involves a top-mounted hopper system that feeds thermoplastic resin through an extruder barrel. With the help of heat and pressure, the plastic takes the shape of the mold. Manufacturers can incorporate additives like colorants and UV inhibitors to enhance the appearance or performance of the final product.  

Extrusion works with a variety of thermoplastic materials, including:

  • extrusionTeflon PTFE
  • Nylon (6, 6/6, MDS)
  • Polypropylene (PP)
  • Low-density polyethylene (LDPE)
  • High-density polyethylene (HDPE)
  • High-impact polystyrene (HIPS)
  • Flexible polyvinyl chloride (PVC)
  • Acrylonitrile butadiene styrene (ABS)
  • Thermoplastic elastomers (Santoprene®)
  • Polyethylene terephthalate glycol (PETG or Codar®)

There are five main types of plastic extrusion methods that use different types of extrusion dies. We will describe the benefits and applications of each type of extrusion to help you determine the ideal method for your application.

Sheet Extrusion

Sheet extrusion works by extruding a molten plastic material in powder, flake, granule, or pellet form through a die into a flat shape. Rollers cool the sheets, which can be between 0.2 and 15 mm. Thin sheets are ideal for consumer products, while thicker sheets are best for industrial or commercial applications. The following are examples of applications for these extruded flat sheets:

  • Washers
  • Spacers
  • Discs
  • Fasteners
  • Gaskets
  • Insulators
  • Shims
  • Tags
  • And more

A Guide to Plastic Stamping

Plastic stamping is a manufacturing process that enables the creation of very thin parts. Typically, this process utilizes a set of dies and a punch press. The press is available in both conventional and high speed options, with varying tonnages depending on the equipment. This machinery is able to punch a shape from a non-metallic substance such as extruded plastic. Manufacturers can utilize plastic stamping to create an array of flat shapes, including gaskets and washers.

What Dies Are Used in Plastic Stamping?

CNC punching machine

Dies are highly versatile, with applications across a wide range of industries. The plastic stamping process will most commonly utilize a compound die, which consists of two separate dies. One cuts the outside diameter of the workpiece, while the other punches the interior. After the plastic stamping is complete, high pressurized air will blow away any excess material. The benefit of compound dies is that they enable all stamping to be completed in a single stroke, rather than two separate strokes.

New Process Fibre differs from many other stamping companies, as we specialize in stamping high performance non-metallic materials. We offer an array of stamping solutions, from single stroke compound dies to high-speed progressive dies.
