About Nylon Plastic

Nylon plastic is a common thermoplastic engineering material, which was developed by DuPont company in 1938, and its density is 1.15 g/cm3. Normally, it is frequently used as a replacement for bronze, brass, aluminum, steel, and other metals, as well as other plastics, wood, and rubber. Some people call it different names, for example, Polyamide, PA, PA6, PA66, Nylon 6, Nylon 66, Cast Nylon, etc. Nylon plastics are classified according to numbers (6, 66, 11, 12, etc.), which means molecular structures. The common types are PA 6, PA 66, PA 610, PA 4,6, PA 6,9, PA 612, PA 11, and PA 12.

Nylon plastic has better tensile strength and bending stiffness than Acetal plastic (Polyoxymethylene POM) but offers a poor Water Absorption Rating. Nylon plastic offers excellent impact resistance, lightweight, good stiffness, low frictional properties, and outstanding wear properties. It also has very good temperature, chemical, and impact resistance properties. Normally, Nylon is frequently used to replace metal bearings and bushings often eliminating the need for external lubrication. Other benefits include reduced part weight, less operating noise, and decreased wear on mating parts.

The standard stock shapes of Nylon are sheet, rod, and tube, which are produced by the cast molding and extrusion processes. The main materials are Nylon 6 (PA6) and Nylon 66 (PA66). Then, you can use a cutting machine or CNC machine to machine them into parts. The natural color of the Nylon Sheet/Rod/Tube is off-white. In addition, you can find Black, Green, Blue, Red, etc. Injection molding is another process that involves large quantities of nylon parts. 3D printing is a popular process for low-quantity Nylon parts.

Some manufacturers can get the enhanced Cast Nylon Sheets in some physical properties by adding different additives, such as Glass Fibers, Oil, Solid Lubricant, MoS2 (Molybdenum Disulfide), Elastomer, etc. They are called Unfilled Nylon, Glass-filled Nylon, Oil-filled Nylon, MoS2-filled Nylon, and Moly-filled Nylon.

Frequently Asked Questions about Nylon

PA6 nylon is a very strong and rigid thermoplastic. It has a very high tensile strength, ranging from 9400 psi to 13900 psi. Though it is a highly strong material, with good elasticity, it is also a flexible plastic.

Nylon has much better impact resistance characteristics. Its impact resistance is almost 10 times higher than ABS plastic.

Nylon plastic forms chains with carbon and hydrogen monomers. The process that forms the chains to the amide group is called condensation polymerization. Hence, it is called polyamide.

Both nylon have differences in their structure. Nylon 6 is polycaprolactam. But Nylon 66 is poly hexamethylene adipate. The wear resistance of Nylon 6 is slightly better than Nylon 66. But the differences are indistinguishable.

Both have a slight difference in melting point. Nylon 6 has a melting point of around 220℃, and Nylon 66’s melting point is around 260℃.

No, nylon isn’t toxic. In normal conditions, nylon is considered safe to use. It is even a very common plastic used in the food industry.

However, if heated at very high temperatures, it can release hydrogen chloride. But this temperature range is very high, ranging from 350℃ to 500℃.

Nylon plastic is used in many industries, including food, packaging, medicine, textile, and agriculture. It is also used in the marine industry, industrial applications, automobiles, and electronics.

Components made from nylon include bearings and bushings, gears and sprockets, shirts, foundation garments, etc. Packaging machinery parts, insulators, seals and gaskets, etc., are also made from nylon.

Yes, you can recycle nylon. This is because nylon is a thermoplastic that doesn’t decompose that easily. You can melt nylon at a temperature ranging from 220°C to 260°C.

Since it doesn’t decompose in the environment for hundreds of years, recycling it is a good idea to safeguard the environment.

Yes, PA66 is a water-absorbent thermoplastic. The rate of water absorption for PA66 is generally 2.5%. But, it can absorb up to 8.5% water under 23°C when submerged for 24 hours.

Yes, PA66 is UV-resistant and a good choice for applications under sun exposure. However, PA 6 has a slightly better UV resistance than PA66. They both are good for outdoor usage.

But over time, PA66 degrades under regular prolonged exposure to the sun, and becomes brittle.

The melting point of PA66 is around 260°C. But it can provide services under a continuous temperature of 90°C, and this can go up to 105°C based on thickness. And the decomposition temperature for PA66 ranges from 350℃ to 500℃.

Yes, PA6 is flexible. It has a lower elastic modulus and better elastic recovery characteristics. These characteristics make it softer, and more flexible.

So, you can easily form Nylon 6 or PA6 in any shape. This is why nylon is a popular material used to manufacture flexible conduits and ropes.

Yes, PA66 can be glass-filled. Actually, glass-filled PA66 is the most common filled nylon. It generally has 30% glass-filling. Aside from glass-filled PA66, oil-filled, moly-filled, MoS2-filled, etc., PA66 are available.

Concentrated acids like hydrochloric acid, nitric acid, and sulfuric acid can dissolve and destroy nylon. Aside from these, phenols, saturated methanol, and calcium chloride can also dissolve nylon.

A mixture of trifluoroacetic acid (TFA) and acetone can dissolve nylon 66.

The price of nylon varies based on the types, grades, and filling. We request you to ask us for a quote of your particular requirements.

Yes, both PA6 and PA66 nylons can be injection molded. As a result, you will get high efficiency and fast production from nylon. Injection molding is cost-effective and ensures low waste of materials.

Aside from injection molding, you can also mold nylon with cast molding and an extrusion process.

No, pure nylon doesn’t shrink easily. The rate of shrinkage of PA6 is  1%-3%, and PA66 is 0.5%-1.5% when exposed to heat or other environmental factors.

But, if the nylon is blended with other materials, the shrinkage percentage will be higher than usual.
