UV radiation can be caused by natural sunlight or artificial sources, such as tanning beds. To minimize the effects of UV radiation on nylon, it is best to keep the material out of direct sunlight and away from other artificial sources of UV radiation. Additionally, many products made of nylon are now treated with UV-blocking finishes, which help protect the material from the damaging effects of UV radiation.

Susceptibility to Hydrolysis

One of the main weaknesses of nylon is its susceptibility to hydrolysis. This occurs when water molecules react with the polymer chains of nylon, breaking them down and reducing the strength and durability of the material. This can cause the material to become brittle, leading to cracks and tears. For this reason, nylon should not be stored in high humidity or exposed to moisture for extended periods of time. Additionally, nylon is not resistant to strong acids, bases, and solvents, which can damage the material and cause it to degrade.

Reactivity to Acids and Bases

Nylon is a synthetic polymer with many useful properties, but it does have some weaknesses that should be taken into consideration. One of the main weaknesses of nylon is its reactivity to acids and bases. Nylon is vulnerable to hydrolysis, which is a chemical reaction that occurs when it comes into contact with an acid or a base. This reaction can cause the nylon to become brittle and eventually break down. It can also cause discoloration and other changes in the material. It’s important to be aware of this when selecting nylon for an application, and to take the necessary precautions to protect it from any potential exposure to acids or bases.

Physical Properties of Nylon

Nylon is a versatile material with many desirable properties, but like all materials, it also has some weaknesses. When considering the physical properties of nylon, some of the weaknesses to be aware of include a lack of UV resistance, a tendency to creep and a low melting point.

UV Resistance: Nylon is not naturally resistant to ultraviolet (UV) radiation. Over time, exposure to UV light can cause the material to degrade and lose strength, making it unsuitable for outdoor applications.

Creep: Nylon is known for its tendency to creep, which is the gradual deformation of the material under the influence of an applied load. This property can limit the use of nylon in applications where the load is static, such as a bearing or a belt.

Melting Point: Nylon has a relatively low melting point, which means that it may be unsuitable for high-temperature applications.

Although nylon has some weaknesses, its many desirable properties and versatile nature make it a popular choice in many engineering and industrial applications.

Low Tensile Strength

One of the primary weaknesses of nylon is its low tensile strength. This means that nylon is not able to withstand a great deal of tension before it breaks or deforms. Nylon is also less durable than other polymers, so it is not ideal for situations that require strong, long-lasting materials. Additionally, nylon is not particularly resistant to heat and can become brittle when exposed to higher temperatures.

Poor Abrasion Resistance

Nylon is a popular synthetic material for many applications due to its strength and durability, but it does have a few weaknesses, one of which is poor abrasion resistance. Abrasion resistance is the ability to withstand wear and tear from repeated contact. Nylon is not a good choice for applications that require high levels of abrasion resistance because it tends to wear down quickly when subjected to friction. This may limit its usefulness in certain situations, such as tires, conveyor belts, and other high-wear applications.

Limited Heat Resistance

Nylon is a strong and durable synthetic material, but it has some weaknesses that should be taken into consideration when selecting a material for a given application. One of the main weaknesses of nylon is its limited heat resistance. Nylon has a relatively low melting temperature and can be damaged by temperatures above 120°C (248°F). This means that nylon should not be used in applications where exposure to higher temperatures is likely. In addition, nylon may degrade over time when exposed to sunlight and other sources of heat, so it is important to select the appropriate grade of nylon for a given application.

Environmental Impact

Nylon is a highly versatile material, but its environmental impact should not be overlooked. Nylon production requires large amounts of energy and water, and the material is not biodegradable. This means that the production of nylon is a strain on natural resources and that it can have a lasting effect on the environment. In addition, nylon is composed of petroleum-based substances which can emit hazardous fumes during production. Therefore, it is important to consider the environmental impact when making decisions about using nylon.

Cost of Production

When it comes to the cost of production, nylon is not the most economical choice of materials. The costs of nylon production can be quite high due to the energy and materials needed to produce the polymers. Additionally, the cost of the chemical additives needed to give nylon specific properties can be expensive. Furthermore, the cost of the machinery and labor needed to process the polymer into usable products can be a factor in the overall cost of production. As a result, the cost of production for nylon can be higher than other materials such as polyester or polyethylene.

Recycling Potential

Nylon is a synthetic polymer that has several advantages, such as strength, flexibility, and durability. Unfortunately, nylon’s potential for recycling is limited due to the fact that it is a thermoplastic and therefore not easily broken down. This can lead to a strain on resources when it comes to disposing of nylon, as it is difficult to recycle, and non-biodegradable. Furthermore, nylon often contains additives, such as flame retardants, which makes it difficult to separate and repurpose. As a result, nylon often ends up in landfills where it takes hundreds of years to decompose. In order to reduce the amount of nylon waste, it is important to use recycled and recyclable nylon whenever possible, as well as focusing on reducing, reusing and recycling.


Durability is one of the major weaknesses of nylon. Though it is generally considered a strong and resilient material, its resistance to wear and tear can be quite low compared to other materials such as polyester and cotton. Its fibers are not as strong as those of other fabrics and can easily be damaged by sharp objects, heavy loads, and exposure to extreme temperatures. Nylon tends to become less elastic and brittle over time, resulting in a decrease in its strength and longevity. Furthermore, it is highly susceptible to UV damage and can fade or discolor when exposed to prolonged sun exposure.

Thermal Conductivity

Nylon is a strong, lightweight, and flexible material that is widely used in industrial and commercial applications, but it does have several weaknesses. One of the most important weaknesses of nylon is its low thermal conductivity. This means that it does not transfer heat efficiently, making it a poor choice for applications where high heat transfer is necessary.

Nylon does not absorb water, which means that it can become soggy and weakened by dampness or wet conditions. This can lead to the fabric becoming weak and prone to tearing or stretching. Additionally, nylon is susceptible to mildew and mold growth when exposed to moisture, which can cause discoloration and a sour smell. To protect nylon from moisture, it is important to use a waterproofing spray or fabric protector.

Color Retention

Nylon is a versatile and commonly used synthetic fiber, but it does have some weaknesses that should be considered when selecting a fiber for a specific use. One of the weaknesses of nylon is its color retention. Nylon is a poor choice for items that need to retain their color over time, as it is not very resistant to fading. Additionally, it is not a suitable material for items that need to be regularly washed, as the color will fade and change quickly. Furthermore, nylon is not resistant to staining, and colors can be easily transferred from other materials to the nylon fabric. Therefore, when selecting nylon for a specific application, it is important to consider the need for color retention and durability.


Moldability is one of the key weaknesses of nylon. Nylon is not easily molded into complex shapes, and it is not suitable for processes requiring high precision or accuracy, such as injection molding. Nylon also has a relatively low melting point, which can make it difficult to achieve a good surface finish. Additionally, nylon is not resistant to high temperatures, so it cannot be used in applications that require extreme heat. Finally, nylon is not compatible with many adhesives, which can limit its usefulness in certain applications.
